No I cannot access DVD on installed system.

No, I meant I get that error each time I try to launch the reboot command.

Also: CS:IP (E800:6DA) is always "2E 0F 01 16 78 06 0F 20" which according to 
debug is LGDT CS:[0678]

hum... will have to check more closely

I did remove I=B000-B7FF and I=TEST like suggested elsewhere... with no real 
change.

I should read doc to understand more...

Works pretty well with NANSI loaded... there where one string not at the right 
place however

Seems unlikely... because of integrated intel 





EMPONG : CS:EIP (F3EC:2B) was 0f 01 54 08 2E 0f 01 1E... which decoded to LGDT 
[SI+08] ... LGDT again.
