mutiboot usb dos 6.22 installer iso

[illusions]

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.

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) <-------------

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

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)

map --hook

root (0xff)

chainloader (0xff)
