[syslinux] memdisk via PXE for DOS+firmware upgrade

[Ercolino de spiacico]

Hello

I'm trying to boot freedos/msdos from PXE to run a BIOS & firmware upgrade on my machines.

e.g.

LABEL FIRMWARE
MENU LABEL FIRMWARE UPDATE
kernel memdisk
APPEND iso initrd=firmware.iso raw


I can boot either the 1.44 virtual floppy (.img) or the ISO with the .img files added as
boot. When I boot up it gets the first line in the autoexec.bat:

MSCDEX.EXE /D:MSCD0001 /L:X

and seems to run run successfully, however if I go into X: it does change drive letter
but I also get an error/abort/fail something.

I think I really miss something here

Any help?

NOTE: the firmware is 8Mb so saving it in the .img is not an option unfortunately.

Thanks!!!!
:-)
