The FreeDOS 1.0 ISO is confirmed to be working under normal PC BIOS when
booting from CDROM.
I guess your environment is a modern CPU with virtualisation extensions
present and enabled? (as I don't think Syslinux, Memdisk nor FreeDOS
kernel have built-in support for acting as XEN client).
FreeDOS 1.0 ISO works like this:
1) Boot from CDROM in non-emulation mode
2) Load isolinux.bin (old version, version 3.62 is latest release)
3) Load isolinux.cfg configuration file
4) Press 1 to load FreeDOS (loads Memdisk, then loads
/ISOLINUX/DATA/FDBOOT.IMG, which is a compressed 360KB bootable floppy
image file )
5) FDBOOT.IMG gets uncompressed in RAM, then is being executed (in RAM)
by Memdisk in uncompressed form.
6) Bootsector is loaded, which in turn loads Kernel.sys (FreeDOS kernel)
7) Kernel.sys goes looking for \FDCONFIG.SYS and if that doesn't exist,
\FDCONFIG.SYS. If that also fails, \COMMAND.COM
8) Selecting an option loads drivers and COMMAND.COM, then starts batchfile
Knowing the layout of the 360KB diskette, I'd say the FreeDOS kernel is
not able to find any files (don't see any menu option in your screenshot
which points to no config.sys being found..nor can kernel find
command.com). I don't know if XEN is to blame for this, or Syslinux,
Memdisk or FreeDOS, or any combination of these issues.
Could you refer me to the site which has a web-archive of the responses
for the XEN mailinglists? Can't see if any threads with solutions were
Alternative options are to remaster the ISO with 1.44MB floppy emulation
enabled instead of non-emulation with Isolinux. Or ofcourse try a
bootdisk first, instead of a bootable cdrom.
