Hi
I have put coreboot+seabios on an old Tyan S2895 I have just retired when the 2nd CPU socket stopped working probably because some of the caps are bulging... it is stable anyways on 1 CPU with Tyan BIOS.
Booting into Linux 3.2 amd64 on SATA - grub works fine and the drives are detected by the kernel but then I get lots of SATA errors, the USB root hubs are detected but no devices, I get no onboard ethernet...
One potential issue is when I booted the board under systemrescuecd flashrom can no longer see the chip... I shelled out $10 for a new chip but that may take a couple of weeks to wing it's way here from the USA.
I should put some new caps in but there is a chance I will brick the board very permanently doing that so if there is anything I can do to help fixup the S2985 port beforehand let me know, as maybe the board will end up in the trash if I can't use it for anything interesting.
Maybe I can hotswap and reflash the chip in another Tyan Opteron board of a similar vintage (I have a couple); is there a point in time where I can roll back to and have a better chance of building a coreboot that works better?
thanks
Andrew
I have been able to flash it back using the Tyan tool under FreeDOS, this is what the dmesg looks like with the Tyan BIOS
