Hi,

I am unable to get the mutiboot dos 6.22.iso installer to work in grub4dos. But on mutiboot cd it does work.
Grub4dos was able to start the dos 6.22 installer but it stop at setup

"Your first hard disk is not currently configured for use with MS-DOS ... "
Dos installer assumed the bootable USB is the first hard drive.

Is there any command line I should add in grub4dos to prevent this ?


menu.1st ------------------------


title MS-DOS 6.22 - iso\n install dos 6.22
map --mem /DOS622.iso (0xff)
map --hook
root (0xff)
chainloader (0xff)


on cd boot

config.sys ------------------------

DEVICE=HIMEM.SYS /testmem:off
FILES=30
BUFFERS=20
DEVICE=eltorito.sys /D:vir


LASTDRIVE=Z

autoexec.bat ------------------------

@echo off
rem load cd content to virtual cdrom x:
MSCDEX /D:vir /L:x
path a:;c:;c:\dos;c:\supp;c:\windows;x:;x:\win311;x:\dos

cls
echo.
echo ********************************

echo Welcome to the "MS-DOS 6.22" installation process,

x:
SETUP.exe

ah ... finally figure it out



title MS-DOS 6.22 - iso\n Install MS-DOS 6.22 or Windows 3.31
map --mem /DOS622w.iso (0xff)
map --hook
map (hd0) (hd1) <-------------
map (hd1) (hd0) <-------------
root (0xff)
chainloader (0xff)

Actually you should in theory also hook the re-mapping of the hard disks:
