[9fans] driver for old vga? (trident microsystems tvga8900)

[Axel Belinfante]

I'm trying to put some old hardware (back) to work.
In particular, a very old video card that in the bios
says TRIDENT MICROSYSTEMS and has a chip labeled tvga8900 .
(TRIDENT TVGA BIOS C2.1?)

This card did work with the 4-floppy 2nd edition distribution.
Unfortunately, I was not (yet) able to access the old vgadb.
Any chance that there is still a driver for it in 4th edition?
Or an old 2nd edition one that I could try to reintegrate?
Essentially, the system will be used as a server,
so it is not a big deal, but would still be nice...

I could not get the old vgadb from the old disk containing
the 4-floppy install, because, with that disk in the system
I'm trying to get working I get a kernel panic on boot.

dev A0 port 170 config 0A5A capabilities 0001 mwdma 0000
FLAGS=10246 TRAP=0 ECODE=0 PC=80022367
  AX fffffffe  BX 00000000  CX  00000200 DX ffffffff

I can't find any trace of a Trident TVGA 8900
in the 2e sources or vgadb.  There are no
bios strings looking looking anything like
TRIDENT TVGA BIOS C2.1.

The card probably only worked in 640x480x1
(one of the only standardized graphical VGA modes)
which is no longer an option.

i was going to comment that this was funny and that
no one would want to go near a 2e boot process crash,
but then i realized this isn't a 2e boot process crash.
that "dev A0 ..." line is from devsd, which appeared in 3e.
i don't remember whether the 9load (nee b.com) panics
looked the same.

Sorry for the confusion (or the fun? :-).
This panic I got with a 4th edition kernel.

(however, I remember that that disk gave me an
 occasional 'weird interrupt ignored'
 (or similar wording))

That must be it :-( (oh well, it was for a server anyway)
Thanks,
