Hello @ all,
I try to run LinuxBios on an Via Epia ML6000 and there are problems with the VGA output.
The chipset on the board is nearly the same as the Epia-M and the console output seems to be ok, only the initialisation of the video bios looks not fine.
The video bios is taken from the original Bios with dd. Kernel is compiled with standard fb support. X fails, because of the non exist /dev/fb0. Furthermore, there is no detecting of the graphic hardware, if the kernel starts.
Please have a look at my file.
any hints?
regards chris

This needs to be implemented in LinuxBIOS.

Hmmm, however :D
Currently, I looked in several bios.rom images on the via website. I recognized that the latest images from Epia-ML and Epia-M have the same VGABIOS Name and Size. Somewhere I have read that the latest Epia-M Bios makes trouble with LinuxBios, if you extract the VGABIOS from that file. Also their was a link to an older Bios of the Epia-M (I think it is epia-m, but I'm not sure). This bios file contains an different VGABIOS (name and size) and now I will try this VGABIOS.
Good luck ;)
But one question, should I fill the video.image to 65536 with zero?

I missed this earlier. This indicates that the loader do_vgabios() was unable to find the bios extension signature of 0xAA55 using the base offset of 0xfffc0000. Your video bios was _NOT_ copied to ram.
biosint: # 0x10, eax 0x4f14 ebx 0x18003 ecx 0x1 edx 0x0 biosint: ebp 0x17fa8 esp 0xffa edi 0x0 esi 0xffff70b6 biosint: ip 0x8e22 cs 0x0 flags 0x46 BIOSINT: Unsupport int #0x10
This is probally the result of vga_enable_console() which is called regardless of what happens in do_vgabios() so I think its just running bogus code.
Your rom image does not have the vga bios located correctly. You must locate the video bios in your ROM image such that it will get referenced at 0xfffc0000.
For a ROM image that is 256k in size that means you need a 64k VGA bios image located at offset 0x0. The linuxbios image can then start at offset 0x10000.
If you do a 'hd' on your ROM image file the very first word you see should be 0x55aa which is the 0xaa55 rom signature in little endian.
Since the build system should have done all this for you I'm guessing that your vga bios image is not valid.

Or it is corrupt to begin with.

Well, it could be that the dd comand to get the video.bios from original bios has had the false values for skip. The epia-ml vgabios is smaller than the epia-m vgabios and eventually located on another place in memory
However, I have tested the epia-m vgabios extracted with award bios editor from the older bios version, and the vga console comes up, if the kernel is loaded :D Unfortunatly, there is no fb0 and X fails.
Doesn't matter, I have also extracted the original vga bios from bios and will try it again.
For a ROM image that is 256k in size that means you need a 64k VGA bios image located at offset 0x0. The linuxbios image can then start at offset 0x10000.

I will have a look ;)

Jip, i totally agree. The first vgabios i get with dd is shit :D

Right, the VGABIOS I have got with the dd command was not valid. It starts with another word as it should.
But, the newer right extracted ones fail on booting, too. At the moment I use the prefered one from the older Epia-M Bios and the vga comes up, if filo run.
Furthermore, there is a second problem for me. Linuxbios needs about 10 seconds to output the first messages. Stefan means, it is a hardware problem. Have somebody else this problem ??
What does Linuxbios first to initialize the Hardware? And what could take so long time? The rest of the initializing seems to be ok.

It's not using an emulator. Thats fall back to 16-bit mode and running the bios.
See here:
http://www.openbios.org/pipermail/linuxbios/2005-October/012723.html
Should we file a report with the issue tracker that the emulator does not work with via video bios?

The Mach 64 ATI bios had some of these as well but it was just for requesting what type of LCD panel (if any) was attached.

Please do. It should not be too hard to get this right..

Hm.. if the video bios provides these, does it require to support interrupt callback installs?

It was previously reported here that this works if you take the video bios from a 1.1.13 bios, but not if you use the newer 1.1.16 version. The older one is not it seems on VIAs site anymore, but a poster offered a link to a saved copy. -jrg
