[LinuxBIOS] Problems with Intel vga working

[Joseph Smith]

Hello,
I have followed the vga support documentaion to a "T" but I don't get  
any vga output when I boot, only serial. I have tried several  
different ersions of the vga rom with no luck. Has anyone else had any  
success with integrated vga on an Intel board? Is there anyway to  
debug this to find out what is happening?

Here is my lspci -v:
00:02.0 VGA compatible controller: Intel Corporation 82830 CGC  
[Chipset Graphics Controller] (rev 04) (prog-if 00 [VGA])
    Flags: bus master, fast devsel, latency 0, IRQ 7
    Memory at f0000000 (32-bit, prefetchable) [size=128M]
    Memory at ffa80000 (32-bit, non-prefetchable) [size=512K]
    Capabilities: [d0] Power Management version 1

00:02.1 Display controller: Intel Corporation 82830 CGC [Chipset  
Graphics Controller]
    Flags: bus master, fast devsel, latency 0
    Memory at e8000000 (32-bit, prefetchable) [size=128M]
    Memory at ff980000 (32-bit, non-prefetchable) [size=512K]
    Capabilities: [d0] Power Management version 1

Here is what my Conif.lb looks like:
    	device pci 2.0 on         # VGA compatible controller: Intel  
Corporation 82830 CGC
    		chip drivers/pci/onboard
    			device pci 2.1 on end	# Display controller: Intel Corporation 82830 CGC
    			register "rom_address" = "0xfff80000"
    		end
    	end

Thanks - Joe

Is there any indication of what the problem is in the boot messages?

Have you tried using both vm86 and x86emu?

No, I have the debugging level on 9 and it boots just fine, no errors  
but only on console. I have not used vm86 or x86emu, I am using a live  
system, does that make a
diference?

Could you send the full messages to the list?

The VGA BIOS is always executed by LB using either x86emu or vm86,
never directly on hardware. Which one works best differs from one
VGA BIOS to another, so it's always a good idea to try both.
I'm not sure exactly how you switch. You may have to copy a bit of
code around.
