I'm looking for PCI video graphics cards for Linux/MIPS. Does anyone
has a recommendation?
Some video card have x86 BIOS ROM on them and Dan Aizenstros gave us
the information we can emulate the x86 BIOS code. But since the size of
memory on our system is restricted, I'm looking for PCI video cards
which does not have BIOS, and is easy to buy, and hopefully are
working on MIPS system already.
Thanks in advance.

I ported the MILO x86emu code to PMON. The x86emu code runs
the VGA BIOS on the ATI card and the card appears to initialize
okay. The only issue may be that the ATI BIOS may calculate
timings incorrectly. However, the text mode appears to run and
I can use the BIOS to display text on the screen when running PMON.
The Linux framebuffer driver is also able to display text but I
believe it is doing so in graphics mode.
