Onboard VGA

[Bao C. Ha]

Hello,

How do I modify the Config.lb file to accomodate the onboard VGA?
Following is the relevant lspci:

01:00.0 VGA compatible controller: VIA Technologies, Inc. UniChrome Pro
IGP (rev 01) (prog-if 00 [VGA])
        Subsystem: VIA Technologies, Inc. UniChrome Pro IGP
        Flags: bus master, 66MHz, medium devsel, latency 32, IRQ 5
        Memory at f4000000 (32-bit, prefetchable) [size=64M]
        Memory at fb000000 (32-bit, non-prefetchable) [size=16M]
        [virtual] Expansion ROM at fc000000 [disabled] [size=64K]
        Capabilities: <access denied>

I don't think "device pci 01:00.0" is correct.

Thanks.
Bao

Have a look at the via/epia-m. Via hardware needs vm86, which is part of the
epia-m target. It's called in mainboard.c, and the code is in vgabios.c or
something similar.

Hi Corey,

It's not quite the Via Epia-m, but more like the Via CN10000
with the cn700 northbridge and vt8237r southbridge.

I am trying to modify the via/epia-m files to reflex the
differences.

Thanks.

What I had to do for the cn700 was vm86+bochs bios. Copy the bochs bios to
0xf0000, then run the vga bios (minus the console init part). Unfortunately,
all that work went down the tubes when I got my new laptop and completely
screwed up the file transfer. I've been trying to redo it, but I've had
other projects to work on, too. Good luck!
