if you type f8 and keep himem.sys form loading then you get up clearly! :-)

And what suirprise:
	Wenn you reboot (ctrl+alt+remove) after get up a dos boot disk you do not 
	need to remove the himem.sys. (but still not working.)

CD -Support broken?
	I can boot nearly every Boot-Cd i have tryed (Knoppix, Debian-Install, Suse, 
Windows98, Dos-BootCD, NowelDos-BootCD).
	But after booting the Bootimage on CD they all faild to find the CD Device 
for loading/mounting.
