Subject: [9fans] 9load hangs in floppygetfspart dosinit

I have a machine containing an AGP and a PCI video card.
The PCI card is supported; when I set the bios to init PCI first
everything works fine.

I switched the (AGP) video card (from unsupported diamond fire 1k pro)
to (I hoped supported) Hercules 3d prophet II mx, based on nvidia
geforce2 mx).

With the diamond fire card booting with 'init agp first'
would work fine, but (of course) no graphical mode (card unsupported)

With the hercules card, when booting with 'init AGP first',
9load hangs after printing the apm line, before printing
the 'using fd0!...plan9.ini' line.


I'm trying to add print statemtents to see what's going on.
I'll continue to do so, but I hope maybe someone has a good idea
that's faster than my tedious debugging...

it seems that floppyinit is executed wholly,
but in dosinit it hangs; I see

seek to 0 succeded
floppyon in (added myself)
floppyrevive in
sra 29 srb 7b dor c msr 80 dir 8
floppyrevive out
sra 9 srb 73 dor c msr 80 dir 8

and that's where I am right now.

Axel.
