Hi!
I'm the proud owner of two 800CTs: One with a P100 and 16MB RAM, the other with P166MMX and 48MB RAM.
Recently I fiddled around with the OmniBook Support Utility Disk and found three tiny tools there: DOCK.COM, EXTFLOP.COM, and IDE.COM
DOCK.COM source code:
EXTFLOP.COM source code:
IDE.COM source code:
Source code is for the R86 assembler, which is part of http://www.lsi-j.co.jp/freesoft/. Don't ask, I just like R86.
But this source code is easy to convert to NASM or even DEBUG.
Now my problem is, these tools don't work for me.
Whatever I try, ports 66h and 67h always return FFh. I also verified with DEBUG.
Okay, EXTFLOP.COM is never called from the Utility Disk, but DOCK.COM is.
(I didn't try IDE.COM, as it also reads the same status byte EXTFLOP.COM.)
What I already tried:
Am I doing something wrong?
Would be nice, if some other people could try on their own machines.
OmniBooks 300, 425, 430, 530, 600, are probably worth to try own too.

; --- Kill all the upper bits.
and al, 1
