[LinuxBIOS] Success report on VIA EPIA-M10000

[Leon Woestenberg]

Hello all,

just wanted to report that I have gotten my EPIA-M10000 to boot 
LinuxBIOS 2184, then FILO 0.4.2, then Ubuntu with kernel 2.6.12 into X 
without problems.
This time round (for learning purposes) I extracted the VGA BIOS from 
the BIOS upgrade file, and not from a running EPIA. (Still note that 
there is an error in the EPIA HOWTO about how to extract the VGA BIOS 
from memory. -- See my messages of the past few days for context.)

For completeness, here is a small diff, plus an adapted Makefile that 
made this work.

Thanks for all the work you guys have put into it.

Next up is inclusion of the ACPI table.

Regards,

Leon.

This is intriguing.

-     dev = dev_find_device(PCI_VENDOR_ID _VIA, 0x3123, 0);
+     dev = dev_find_device(PCI_VENDOR_ID_VIA, 0x3122, 0);

I think what this means is that we need a new mainboard directory. can you
give me more info about the exact mainboard.

Another option, is to do something like tihs:
dev = dev_find_device(PCI_VENDOR_ID_VIA, 0x3123, 0);
if (! dev)
    dev = dev_find_device(PCI_VENDOR_ID_VIA, 0x3122, 0);

or some such. But if you could tell us the exact vendor etc. that would be
good to know.

thanks

ron

Or, to look for a VGA class device from VIA.

Hello Ron,

first my *unchanged* 2177 already worked in the console, but did make it 
into X; it reported:

VIA(0): Bad V-BIOS checksum.

Chris Suehs then responded to me off-list (Thanks Chris!):
---
I have had the same problem for the via X driver.
There is a failure in the LinuxBios Code for newer Epia M

The vga bios section is not write protected, because the protection
failt for a false Device ID

You should try to change the code to the right ID in mainboard.c for the 
Epia to 3122 in the write_protect_vgabios function

regards chris

So I tried again with 2184 and this single change and it worked; I get 
into my X server without a hiss now.

Ron, what exactly do you want to know further than this?

VIA EPIA-M10000, PCB revision.B

I could output lspci -vv or so if that helps?

Regards,

Leon Woestenberg.

I realize we should do a pci class, but this fix ought to work.

Leon, can you test?

Yes, the fix works.

one last request: can you give us exact details of who you ordered your 
system from, part #s, etc? I want to make it very easy for people to get 
this working.

thanks again
