[9fans] Video card problem..

[Ish]

I was able to boot the PC correctly after install from CD. Comes out that
I was using the old CD. Now, I can use the video card in generic
640x4801x1 (with monitor option set for vga). The card in question is

ATI 3D Charger IIC/4Mb RAM

card documentation says that it can do dotclock to 80MHz
ramdac is "3D Rage II" at 170Mhz

aux/vga finds a string at

0xC0085="ATI MACH64 BIOS P/N 113-40606-112"

link=vga
ctrl=mach64

if I use the above three lines in /lib/vgadb the screen goes blank and
stays blank.

Any pointers?

At 0xC00F0 "CI"

I have made progress. I was intsalling from 1st edition CD, with 2nd
edition it does install correctly from CD. Now I want to get a better
GUI. The card in the PC is:

ATI 3D Charger IIC/4Mb RAM

card documentation says that it can do dotclock to 80MHz
ramdac is "3D Rage II" at 170Mhz

aux/vga finds a string at

0xC0085="ATI MACH64 BIOS P/N 113-40606-112"

link=vga
ctrl=mach64

if I use the above three lines in /lib/vgadb the screen goes blank and
stays blank.

If the card is a fairly recent ATI Rage-based one then the 'mach64' code
in the Plan 9 CD distribution won't handle it. We probably have code to do it
but it would require so much extra stuff it would be best to wait for it
to be bundled up somehow. I believe others in the Plan 9 community have Rage
cards working, perhaps someone else can help.

If you look in the BIOS for another "MACH64xx" string near 0xC00F0 the two
letters 'xx' would let me know if it is supported or not.

Did you add those lines?  I don't see them
in the vgadb on the CD.  Adding support for
a new card usually consists of more than just adding
the entry to the database -- unfortunately all 
Mach 64s are not the same.  Sadly the card is
probably just not supported.
