Sorry. My bad. I forget about the lingo sometimes.
post or rather POST. Power On Self Test. The video bios people call
a card that has been initialized by the BIOS 'posted.' Probally
because it happens during the BIOS which used to be much more of a
POST. Nowdays BIOS is a whole different beast but the 'posting' term
remained.
posted = initialized.
Ok,
now I have done a few tests with a extra vga card.
There a no settings in the factory bios for that case. If I remember
right, than they are hidden. I have had a look long time ago with
awardbin on the orginal bios.bin.
However, the system detects the card first and posted them ;)
What should I do? How can I disable the posted card correctly.
Look at the attachment. With command=0 it is possible to unset the IO
and Mem from + to - but I think that is not enough. VGA is still running.
If I try to run testbios after set IO/MEM to - the result is nearly the
same as I boot with LB.
If I run testbios without unsetting the IO Range, the output is very
different from all others. There are a few more calls. I will attach
this output later, because after those experiments I have to do my best
to restart the system :D
Unfortanetly I know nothing about PCI Registers and commands
Thanks
