71 - Grubutils - menuset, wenv, bios, grub4dos utilities and batch files

The GrubUtils utilites can be downloaded from Chenalls site here (this includes wenv, chkpci and other utilities). See the bottom of this page for a recent version (includes 2014 version of chkpci).

There are some interesting utilities that can be called or executed from grub4dos. The documentation is difficult to find and is usually in Chinese. Here are some notes which may be helpful.

When running an external grub4dos batch file or utility executable, you need to copy the file to your boot drive and make sure that the path is specified correctly in the menu.lst file, e.g.

/menuset 0  0  0  0  0   0     10      50           5  29  35

will run the file menuset which must exist on the root of the boot drive. menuset is contained in the grubutils package.

Note: The default command path for grub4dos is the current path (set by the root command) and the /boot/grub folder - it is recommended to place all your utilities in /boot/grub on your boot drive so that grub4dos can find them without needing to set the root or define a full path. 

menuset 0  0  0  0  0   0     10      50           5  29  35

will run the file menuset which must exist  in the /boot/grub folder or in the current root folder (as shown by the ls command).

The alternative is to path each command - e.g. use /bin/wenv instead of just wenv and place the wenv file at /bin.

Grub4dos Batch files

Grub4dos can execute a batch file (usually given a .g4b file extension, but sometime it has a .bat extension or no extension - whereas a grub4dos executable file has a .g4e extension or no extension). The grub4dos batch file must begin with !BAT. The syntax to use in the batch file is similar to that in a menu.lst file but not quite the same. For instance when using two variables together, you must use three % signs in a batch file because any two consecutive % signs will be treated as a single % sign in a batch file:

test.bat file contents:
set a=Fred is a 
set b=GENIOUS!
echo %a%%%b%
echo Fred got 100%% in his test!

in a grub4dos commandline shell, type /test.bat
Fred is a GENIOUS!
Fred got 100% in his test!

Note that in a batch file we cannot use %a%%b% - we must add an extra % symbol and use %a%%%b%, but in a menu.lst file, echo %a%%b% will work and you don't need the extra % sign! 

tip: If you place all utility and batch files in the /boot/grub folder then grub4dos will find them without needing to specify a path.

tip: If you use debug 3 then you can single step a batch file (on later versions of grub4dos use  debug <batchfile>  <args> )

Also, if you call a grub4dos utility a lot in a batch file (for instance, in a loop or subroutine), then load it into memory first using the command insmod - e.g.
insmod /utils/wenv
wenv calc bs=%bs%-%bc2b%
will load wenv into memory so that whenever it is called later (with no path specified) it will run from memory instead of being loaded from the disk each time. Thus using insmod at the start of your batch file to load any utilities into memory will greatly improve the speed of execution! Insmod can also be called from within a menu.lst file and this will increase the speed of execution of grub4dos menus if you call a grub4dos utility within the menu.lst file, as well as any batch files you call afterwards. Use delmod <filename) to unload a file or :

::echo Checking if this batch file is loaded into memory - if not load it for faster execution
delmod -l %~nx0 || insmod %0

#Note: can only use filenames up to 11 characters (including the dot - i.e. up to 8.2 not 8.3) with insmod.

You can also call internal Function calls in a batch file using call Fn.x where x is a number and can be followed by one or more parameters - e.g.:

call Fn.0 0 "Hello"   - will print Hello to the console

Here is a batch file to get lines from a text file, one at a time (redirecting bold blue lines will give a perfect copy of the file):

insmod %0 > nul
set n=0
set l=0
cat --locate=\x0d\x0a --number=1 --skip=%n% /menu.lst > nul
if "%?%"=="0x0" goto :EOF
set /a l=%?% - %n% > nul
::echo -e \nFound CR at start %n% length %l%
if  %l%>=1 cat --skip=%n% --length=%l% /menu.lst
set /a n=%n% + %l% + 2  > nul
goto :LOOP

Tip: to get more lines on the console screen, type graphicsmode 179 first.

Here is a batch file to search for and list BIOS strings. Save the file to your grub4dos bootable disk as ShowBiosStrings.bat, boot to a grub4dos command prompt and then type:

ShowBiosStrings 0x680+0x180 CPU

and see what you get (tip: add insmod %0 to load the whole batch file into memory and speed it up a lot)!
This requires \grub\wenv. If a string is found the GOTSTR=1 is returned.

if "%1"=="FF" goto :FF
if "%1"=="" goto :EOF

:: Requires wenv in grub folder

:: Usage: ShowBiosStrings.bat [memorystart+memoryrange] [string]
::        where memorystart and memoryrange is in units of 512 bytes

::         ShowBiosStrings.bat 0x700+0x80 "cpu\ is\ present"
::         ShowBiosStrings.bat 0x780+0x80 cpu\ is\ present

::  0x680 = D000:0 in memory and is often use for storing DMI BIOS strings
::  0x700 = E000:0 in memory and is used for DMI string as well a BIOS code and workspace
::  0x780 = F000:0 in memory and is usually the BIOS code but may also contain fixed strings

goto :FF

Another Batch file example - use checkdate.g4b to check an Expiry Date

A simple example of an expiry date test (thanks to Wonko on reboot.pro) is:

if 20131226>=%@date:~0,4%%@date:~5,2%%@date:~8,2% pause --wait=3 THIS SOFTWARE HAS EXPIRED - XMAS 2013 IS OVER && halt

Suppose we release a bootable CD or USB drive which has software on it that should be regularly updated. We want to warn the user when it is about to expire or if it has expired. We can use a grub4dos batch file to do this and call it from a menu.lst file like this:

# Usage: /checkdate.g4b <Release Year> <Release Month> <Release DayOfMonth> <ExpiresInDays> [<SILENT>]
# Example below: Released on 2102-12-03   Expires in 30 days
/checkdate.g4b 2012 12 3 30
#  Example1 without text displayed: /checkdate.g4b 2012 12 3 30 SILENT
#  Example2 without text displayed: /checkdate.g4b 2012 12 3 30 > nul
if NOT "%CHECKDATE%"=="OK" reboot

This will show the following text when the grub4dos menu runs...

CheckDate: Release Date 2012-12-31 (Today is 2012-12-31)
CheckDate: This version is good for 30 days from release
CheckDate: This version expires in 29 day(s)


CheckDate: Release Date 2012-12-3 (Today is 2012-12-31)
CheckDate: This version is good for 30 days from release
CheckDate: WARNING: This is older than 30 days!

The checkdate.g4b file can be found at the bottom of this page or click here. If you add the word SILENT to the call parameters then the user will have no idea why it no longer displays a nice menu and just keeps rebooting!

Note: If you are burning this to a CD or DVD, use an 8.3 filename like chkdate.g4b  as checkdate.g4b  is too long a name!

If you wish to 'encrypt' your menu.lst file so that it is not just a plain text file, use 7Zip to compress the menu.lst file to GZip format (menu.lst.gz) and then rename the file to menu.lst. 
grub4dos will still run the compressed menu.lst file just fine but if anyone tries to read the file using a text editor they will find it hard to understand!

Set the System Date

Using the grub4dos Function 53 we can set the Real Time Clock date. The Date.g4b grub4dos batch file can be run to set the date - this might be useful for expiry date sensitive DOS utilities that check the date of the system.

run the batchfile from your menu.lst like this

# set date of system to Jan 30th 2001
/Date.g4b 2001-01-30

# OR ...
# Prompt user to set a date

Note that this will permanently change the date of the system Real Time Clock until you set back the correct time.

grub4dos variables and setlocal/endlocal

Currently there is a maximum limit of 60 variables and each can be up to 512 bytes each.
The batch file VarsLeft.g4b will tell you how many variables remain out of the 60 allowed. It is quite easy to run out if you are not careful!
If you reset them (e.g. set A= will remove the variable A from the environment) then you will free up a 'slot for another variable'.

You can use setlocal to make a copy of the current environment (e.g. variables, root path, current filespec, etc.).
When the endlocal command is run these values are restored and any variables set during the setlocal portion are lost (a copy of the current environment is made when you use setlocal and that copy is restored when you use endlocal).


set l=1
set m=
root (hd0,0)

root (hd1,0)
set l=2
set m=1
echo %l% is 2

echo %l% is 1
echo %m% is empty
echo root command shows (hd0,0) is the root

If you want to use setlocal, but pass back a variable, you can do it by placing an && set x=y statement on the end of the same line as endlocal - like this:

set m=3
set /a m=%m%+1
set n=4
endlocal && set m=%m% && set n=%n%
echo %m% is 4 and %n% is 4

setlocal will inherit the current variables. 
If you have 30 or so variables already set, then when you use setlocal, you will already have 30 variables set - this uses up the variable space (max. 60 variables can be defined). You can clear the local variables using set * : e.g.

set *
# now no variables set
### do stuff here
set A=1
endlocal && set fred=%A%
#now original variables restored + fred=1

There is an undocumented way of getting more than 60 variables in 2013+ versions of grub4dos - see here for details.

Global variables

grub4dos currently supports up to two user-definable global variables.

?_xxxx and ?_yyyy where xxxx and yyyy can be any user defined name - the first two that are set by the user become global, any more are ignored.

set ?_test=test 
set ?_x=x 
set ?_x=
set ?_y=y
echo %?_test%  %?_x% %?_y%

will produce the result:

test  y

Note: set does not list these global variables, nor does set ?_ - you can only see their values if you reference them by name.

Note that  set * will also delete the global variables

setlocal @

You can also use the special parameter @ with setlocal, this will preserve all variables after an endlocal is executed

set doris=
set fred=9

setlocal @
set steve=3
set doris=%fred%
echo ----- level 1

echo ----- level 0 

Produces the output:

----- level 1
----- level 0

Another example when mixing setlocal @ with setlocal

set a=0
setlocal @
set a=1
set a=2
set a=3

When the batch exits, the variable a=1

Batch files that search sub-folders

FFFName.g4b - FindFullFileName - finds the first file matching a full filename, searches all disk - e.g. /grub/FFName.g4b   /  explorer.exe
FFName.g4b - FindFileName - finds the first file matching a filename (without extension), searches all disk - e.g. /grub/FFName.g4b   /  explorer
FFExt.g4b - FindFileExtension -  finds the first file matching a file extension - returns variables - e.g. /grub/FFExt.g4b  /_ISO .iso
DirFile.g4b - lists all files in a single directory (does not list directories)   (e.g.  /grub/DirFil.g4b   /_ISO  DIR   (to just list dir names omit DIR))
LstDir.g4b - Lists directory names in a directory  (e.g.  /grub/LstDir.g4b   /_ISO  DIR   (to just list dir names omit DIR))
LstFExt.g4b - Lists all files in a single folder that match a file extension

The names must be kept to 11 characters - otherwise insmod refuses to load it (says filename too long!). Make sure there are no spaces at the end of the line after the filename or this will be counted too!

Please download FindFile.zip to obtain these batch files.

The batch file LFExt.g4b lists all files in a single speciified folder (and not below - this has been suppressed in the batch file) that match a specified extension, e.g. /LFExt.g4b /_ISO/Linux .iso will list all ISO files e.g.:



Wenv (available on Beta downloads page) is a grub4dos utility (a program - see grubutils section below) that you can run under the grub4dos environment. It is just like an executable that you would run under DOS (e.g. find.exe) but it runs under grub4dos. It allows you to use environment variables in your menu.lst files or to run a script file which can execute grub4dos commands. Note: The Wenv download zip file in the Beta Downloads section of this site also includes an English translation of the Chinese text help file for wenv which I have added for you to study.

 For instance....

title Install Windows 7 64-bit Enterprise Edition\nRun the Windows install DVD to install a copy of Windows to your hard disk
/Imdisk/wenv set iso=/iso/en_windows_7_enterprise_with_sp1_x64_dvd_620201.iso
find --set-root/ImDisk/myiso.cmd
dd if=()/ImDisk/au.xml of=()/AutoUnattend.xml
dd if=()/ImDisk/cr.txt of=()/ImDisk/myiso.cmd
/ImDisk/wenv call write ()/ImDIsk/myiso.cmd SET MYISO=${iso}\r\n
/ImDisk/wenv call map ${iso} (0xff)
map (hd0) (hd1)
map (hd1) (hd0)
map --hook
chainloader (0xff)
    Note that line 2 sets the grub4dos environment variable 'iso' to the path of the ISO file by running the wenv executable with parameters.
    In line 6 and line 7 we can use this variable value by substituting it with ${iso}.
    Note that wenv needs to have a full path as grub4dos needs to find the wenv file which is in the /ImDisk folder in this example.
    Also note that to use environment variables and wenv with grub4dos commands, we need to 'call' the grub4dos command, this why lines 6 and 7 start with '/ImDisk/wenv call'

    If you copy the grub4dos executable file wenv (latest version available on grubutils download page) to the USB drive /ImDisk folder, you can make the menu.lst easier to edit and add more ISO files.

    WENV list of commands currently supported: 

        SET       to set/change/add/delete/display variables - for a substring use :~start,length - e.g.  set a = %xyz:~10,2%%%xyz:~13,2%
                     (note you need to add another % when two %% signs are used together!)

        GET      display variable/variables and get length of the variable in ?_GET internal variable
        FOR      similar to the windows shell FOR cmd instruction
        CALC    simple calculator (priority from left to right, does not support brackets) 
        ECHO    Display a message or variable to the screen 
        READ    a file and run the commands inside - similar to a .cmd batch file (must use WENV supported commands) also supports parameters. 
        CHECK  check if an equation is true or false, if it returns true a command can be executed
        RESET  clear/reset a variable
        CALL     call the grub4dos shell to execute a grub4dos command

    Note: SET, GET, FOR, RESET, CALC and ECHO are largely redundant now as similar functions are built into the latest grub4dos versions from chenall (included in RMPrepUSB).

    For instance, if you type  /wenv set  in the grub4dos command console window, then wenv will display all current grub4dos environment variables.

    Here is another example of how you can use wenv (note: this time wenv is located in the root of the drive and not in the ImDisk folder):

    title Specify an iso file to run
    # list all files in the /boot/imgs folder so the user can see them
    ls /boot/imgs/
    # Ask user which iso they want (name is converted to uppercase as $U is specified)
    /WENV set ask=$U,$input,Enter iso name with no extension (e.g. dban) :  
    /WENV get ask || echo No iso file specified! && configfile (bd)/menu.lst
    /WENV echo Loading /boot/imgs/${ask}.iso - please wait ...
    # run the grub4dos map command and specify the iso file we want to load
    /WENV call map --mem (bd)/boot/imgs/${ask}.iso (0xff)
    map --hook
    chainloader (0xff)

    # Examples using the RUN.bat file (included with the download)
    title Auto-make menu for /BOOT/IMGS/ folder
    # call the RUN batch file and create a configfile in the ramdrive for all image files
    /RUN.bat .Automenu
    # Load the new configfile
    configfile (md)0x3000+0x10

    title Boot dos
    # call the RUN batch file with the file we want to load in the /BOOT/IMGS folder specified
    /RUN.bat DOS622.IMA
    # Add the boot command so the user can use the cursor keys to select this menu entry

    For an example of how to make a script file which can run under grub4dos (which must begin with the text !BAT), see the file RUN.BAT example included with the wenv.zip download.

    For an example of a grub4dos batch file that uses wenv to display the MBR partition table of a drive - see jaclaz's/Wonko the Sane's mbrview.g4b batch file on reboot.pro here.

    Example output of mbrview.g4b batch file from jaclaz.


    Another grub4dos utility you can run is the 'hotkey' utility which allows the user to use hotkeys (e.g. F1, F2, etc.) to select a menu item and run it (use the latest chenall build of grub4dos) - see Tutorial #57 for details.


    'grubutils' is just a name for a collection of individual executable utilities that can run within the grub4dos environment.
    Grub4dos can call these utilities or execute them from a grub4dos batch file or from within a grub4dos menu.lst.

    Some of these will list usage syntax if you use -h switch. C sources are here

    chkpci - lists PCI devices, use -cc:06 (scan class codes that match PCI class 06) [FILE] PCI database file
    diskid (hd0,1) will report Ghost style disk id 1:2
    echo    - echo's chars, variables, etc. = echo -h will display a colour chart of background/foreground
    fatmini - similar to fat but small size, only supports mkfile, copy and del functions
    fontfile - specify a fontfile to load
    g4d_off - quit grub4dos!
    inifile - see below
    mbrcheck (hd1)+1 - checks for a valid mbr (checks a single active ptn table entry, magic bytes, non-overlapping ptns, 
    menuset - changes menu size and position - useful if using a high resolution background
    snake - snake game - use cursor keys to eat the small square
    unifont - load a unifont file
    unitest - test a fontfile for validity
    vbmp -  vbmp /small.bmp   - displays a small monochrome bmp file (must be mono bmp) see here
    vfont - loads a font file??
    wenv - work with environment variables - many functions now in grub4dos anyway - see grub4dos tutorial for details
    wenv-readme.txt - readme file for wenv usage


    Latest 2011 version with -u command here.

    chkpci  [-h] [-o] [-u] [-cc:CC] [-sc:SC] [-srs]  [FILE]

    -h         help
    -u         unique - displays lines in INI file matching h/w IDs
    -cc:CC  scan Class Codes with CC only
    -sc:SC  scan SubClass Codes
    -srs       for SATA/SCSI/RAID - displays mass storage PCI device only - similar to -cc:-1 -sc:06

    fat can perform file operations on a fat volume.

    fat can be downloaded from here.

    Note: for obvious reasons, this does not work on NTFS volumes!

    fat mkfile size=xx filename - create a new file of a certain size (size=* will get size from memory address 0x8290
    fat [/o] copy file1,<length> file2  - copy contents of file1 to file2  - fat copy /o (md)0x300+2,20 (%2)/txtsetup.oem  - copy 20 bytes to txtsetup.oem (/o = overwrite if file already exists) 
    fat ren oldname newname - rename a file or directory
    fat dir - list directory contents - e.g. fat dir /iso/app/  or  fat dir /a-d /grubut~1/ (lists files but not directories, note shortfilenames 8.3 must be used! d,s,r,h valid attributes)
    fat info (disk) - e.g, fat info (hd1,0) - displays info such as FAT start, sectors per cluster, sectors per FAT, free clusters, total clusters, drive free space and size
    fat del file  or directory (dir must be empty)
    fat mkdir newdir
    fat mkfs [/A:UNIT-SIZE] DRIVE - creates fat volume on drive, UNIT_SIZE = cluster size in bytes

    For fat mkfs to work, the size of the device must be approx greater than 66,000 bytes (depending on if mounted using --mem or not). For example, the following two menu entries fail after echo 0 with FAT Error (1) message...

    title test  not --mem
    find --set-root /fat
    insmod /fat
    map (md)0x800+0x5000 (fd1)
    map --hook
    fat mkfs (fd1)
    # 65024 fail, 65025 ok,
    fat mkfile size=65024 (fd1)/test.img
    map   (fd1)/test.img (fd2)
    map --hook
    echo 0
    fat mkfs (fd2)
    echo 1
    fat mkfile size=100 (fd2)/testfd2.img
    ls (fd2)/

    title test --mem
    find --set-root /fat
    insmod /fat
    map (md)0x800+0x5000 (fd1)
    map --hook
    fat mkfs (fd1)
    # 61440 fail, 61441 ok,
    fat mkfile size=61440 (fd1)/test.img
    map  --mem (fd1)/test.img (fd2)
    map --hook
    echo 0
    fat mkfs (fd2)
    echo 1
    fat mkfile size=100 (fd2)/testfd2.img
    ls (fd2)/

    You can only copy the contents of a file to an existing file, so you must create the target file first (must be same size or bigger).


    Here is a batch file called copyff.bat and a menu.lst which uses the fat utility. It creates a large virtual floppy disk in memory and copies the entire contents from a mapped ISO file into it. It can cope with several 100's of files per folder but will not work on very large folders such as the XP CD's /I386 folder in an XP ISO (unfortunately!).

    To make a memory-mapped 2.88MB Floppy disk 0

    # make a disk (8) in memory
    map --mem (md)+5760 (8)
    #hook the interrupt so BIOS can see it
    map --hook
    #good practice to clear memory area start in case confuses g4d if looks like a compressed file header
    echo -e \0\\0\0\0\0\0\0\0\0\0\0 > (8)+1
    #make a FAT16 filesystem 63spt 255trackspercyl
    fat mkfs (8)
    #change to FAT12 BPB
    write --offset=0xc   (8) \2\2\1\0\2\xf0\0\x80\x16\xf0\x09\0\x24\0\2
    #map as floppy 0
    map --mem (8)+1 (0)
    map --rehook
    #remove device (8)
    map --unmap=8
    map --rehook

    Alternate - not using fat mkfs

    :: make 2.88MB floppy as device (8) - Note: 'fat mkfs (8)'  makes a FAT16 disk with 63 hds and 255 spt which may not be recognised as a floppy by Windows
    map --mem (md)+5760 (8)

    sets menu left position to 10, menu width to 50, the first menu item at row 5, 29 items per menu and help text starts at row 35.

    1024x768 background with smaller menu
    In this example the grub4dos version text is not blanked out
    and there is no menu heading.


    If you require the menu to be past column 78 then menuset will not work correctly. In this case use the menusetting utility as follows:

    #/menusetting u    will restore max menu grub4dos default
    # wordspacing linespacing borderwidth tophelp numberofitemsinmenu topstart menuwidth rightstartposofmenu
    set wdspace=0
    set lnspace=0
    set topstart=10
    set rstart=45
    set noitems=10
    set menuw=60
    set bdwidth=5
    set tophelp=23
    /menusetting u
    /menusetting   %wdspace% %lnspace% %bdwidth% %tophelp% %noitems% %topstart% %menuw% %rstart%

    Note that there is a problem with help text with grub4dos - the help text will only appear up to text column 79 - if you have a menu box after column 79 then no help text will appear at all. The default grub4dos help text will always start a column 0, but any menu help text in your titles can only occupy from the left-hand side of your menu box up to column 79. Note: Try the latest 2014 version of grub4dos and grubutils tools - this may now be fixed.

    Example using the settings shown above - note how the help text is cut off at column 79!


    This utility allows you to make any BIOS call you like. You can setup the registers and which interrupt you want to use, it then makes the BIOS call and prints out the CPU register contents after the call returns, like this:

     EAX=00008600  EBX=00000000  ECX=00000000  EDX=00000000  ESI=00000000
     EDI=00000000  EBP=00000000  ESP=00006284  EIP=00000000  eFLAG=00000A83
     DS=0000  ES=0000  FS=0000  GS=0000  SS=0000  CS=0000  OV UP EI NG NZ NA PO CY

    The flag registers are displayed so you can test for the Carry Flag (NC or CY) or Zero flag (NZ or ZR).

    This allows you to make any BIOS call (for instance write characters to a certain position on the screen, read a disk sector, etc.).

    # beep the speaker (if one is fitted) - send a Ctrl-G to the display
    /bios int=0x10 eax=0xe07 ebx=0x0 > nul

    You can then check these registers by redirecting the output to memory and using cat - e.g. a single line in a grub4dos menu ...

    # if plop is not installed, then run it to reboot from USB in USB 2.0 mode
    /plpbt/bios int=0x13 eax=0x504c6f50 ebp=0x43484b44 > (md)0x300+1 && cat --locate="EAX=79657320" (md)0x300+1 || pause --wait=3 loading Plop! && kernel /plpbt/plpbt.bin hiddenusb && boot

    Do not experiment with int13h calls unless you are careful and know what you are doing as they can be dangerous (e.g. could trash your hard disk!).

    Here is an example to calculate available memory size and use the value in your menus:

    #suppress timer countdown and other text
    debug -1

    if "%RUN%"=="" /bios int=0x15 eax=0x0000e801 > (md)0x300+1
    if "%RUN%"=="" cat --skip=24 --length=4 (md)0x300+1 | set n=
    if "%RUN%"=="" set /a MEMSIZE=0x%n%/16+16
    #reload menu once MEMSIZE is set
    if "%RUN%"=="" set RUN=0 && configfile /menu.lst

    pause --wait=2 Memory Size=%MEMSIZE%MB

    <your normal menu entries here>

    iftitle [if %MEMSIZE%>=700 && if exist /myiso.iso] run myiso (needs more than 700MB)

    To use this in an iftitle [if %MEMSIZE%>=600] to run iso that requires more than 600MB - see reboot.pro here. You must load the menu.lst twice - the first time it runs it calculates MEMSIZE, the next time it runs, the iftitle statements will be able to use the MEMSIZE variable and only display the appropriate menus.

    Note: The menu line below will also fetch the memory size from an internal grub4dos storage location and put the value into a variable in units of MBs without needing to call the bios utility:

    set /a MEMSIZE=*0x8298 & 0xffffffff>> 10+1

    Get last physical disk sector (and thus disk size)

    # set size of buffer available
    write 0x6000 0x42 > nul
    # get size of disk from INT 13h AH=48 into memory at DS:SI+10h  - edx=80h is hard disk 0, 81h would be hard disk 1
    # set parameter in buffer area to 0 in case bios call fails
    write 0x60010 0
    # make bios call using grub4dos bios utility
    /bios int=0x13 eax=0x4800 edx=0x80 ds=0x6000 esi=0x0 > nul
    # get returned value for total sectors on disk
    read 0x60010 > nul
    set /A END=%@retval%-1 > nul
    if %END%<=0 echo Drive too big! && exit

    or for larger disks - get capacity in MB or GB

    # DISK can be 0-9, A-F only
    # Returns: CAP = Capacity of disk displayed in GB

    set DISK=0

    # Get disk capacity
    # set size of buffer available
    write 0x6000 0x42 > nul
    write 0x60010 0 > nul
    # get size of disk from INT 13h AH=48 into memory at DS:DI+10h  - edx=80h is hard disk 0, 81h would be hard disk 1
    /%grub%/bios int=0x13 eax=0x4800 edx=0x8%DISK% ds=0x6000 edi=0x0 > nul
    read 0x60010 > nul
    set /A A=%@retval% & 0xffffffff > nul
    set /a CAP=%A%>>21&0xffffffff > nul
    # Get most significant dword
    read 0x60014  > nul
    set /A B=%@retval% & 0x1ffff > nul
    set /a CAP=%B% * 0x800 + %CAP% > nul
    echo DISK %DISK% = %CAP%GiB (LS_DWORD=%A% MS_DWORD=%B%, TOTAL SECTORS=%B%%%A:~2,999%)
    set A=
    set B=

    Get disk bus and type from BIOS

    Here is a batch file that gets the disk bus and disk type using the same AH=48h BIOS call, for the first 3 drives

    # Get Drive Bus and Drive Type from BIOS
    set DRIVE=0
    call :gettype
    set DRIVE=1
    call :gettype
    set DRIVE=2
    call :gettype

    # set buffer size
    write 0x60000 0x42 > nul
    write 0x60010 0 > nul
    /bios int=0x13 eax=0x4800 edx=0x8%DRIVE% ds=0x6000 edi=0x0 > nul

    #"FIBRE" Fibre Channel

    set BUS= && set DTYPE=
    cat --locate=PCI --skip=0x24 --length=4 (md)0x300+1 > nul && set BUS=PCI
    cat --locate=ISA --skip=0x24 --length=4 (md)0x300+1 > nul && set BUS=ISA

    cat --locate=USB --skip=0x28 --length=8 (md)0x300+1 > nul && set DTYPE=USB
    cat --locate="ATA  " --skip=0x28 --length=8 (md)0x300+1 > nul && set DTYPE=ATA
    cat --locate=ATAPI --skip=0x28 --length=8 (md)0x300+1 > nul && set DTYPE=ATAPI
    cat --locate=USB --skip=0x28 --length=8 (md)0x300+1 > nul && set DTYPE=USB
    cat --locate=SCSI --skip=0x28 --length=8 (md)0x300+1 > nul && set DTYPE=SCSI
    cat --locate=1394 --skip=0x28 --length=8 (md)0x300+1 > nul && set DTYPE=IEEE_1394
    cat --locate=FIBRE --skip=0x28 --length=8 (md)0x300+1 > nul && set DTYPE=FIBRE_CHANNEL

    echo Drive %DRIVE% = %BUS% %DTYPE%

    goto :eof

    Note that this does not work if Plop! or the grub4dos USB driver has been loaded first.

    Test for SHIFT key using bios utility

    Here is an example of how you can test to see if the SHIFT key is pressed when the user hits Enter to select a menu item.
    Using these two lines, you can modify the menu commands - for instance, if SHIFT+ENTER is pressed when a menu item is selected, safemode parameters could be used to boot linux rather than normal parameters.

    title Run Linux\nPress SHIFT+ENTER for safe mode
    /bios int=0x16 eax=0x00000200 > (md)0x300+1

    if exist n   calc %n%&3  && echo SHIFT PRESSED!
    #if exist n calc %n%&4  && echo CTRL PRESSED!
    #LShift=01, RShift=02,CTRL=04,ALT=08,SCROLL=10,NUM=20,CAPS=40,INS=80
