Hello,
i tried to get seabios up via payload from coreboot and failed on the
initialisation
of neccessary devices.
The board in Question is a Tyan S4882, consisting of K8 northbridge,
8131 southbridge, 8111 southbridge and Winbond w83627hf SuperIO.
You will see on the following pastebin-url that coreboot does a proper
init and can see all relevant devices.
I was also able to get VGA up via coreboot ( to reflect an accessible
device below root ) but not from within seabios. It probes only against
PCI 00:18.0 ... 00:18.3 which are on the northbridge itself.
I had a look on the sources and found it should see and init the whole
tree, also checked my sources against some patches i found on the net
and they are all applied or superseded.
the seabios was 1.7.1 and master from git
The relevant startup can be found here : http://pastebin.com/wZvRWm1Z
feel free to send me something to test out if there are unanswered
questions or contact me
in #coreboot on freenode's IRC. I'm not omnipresent but 8-12AM and
9-12PM CET should be fine ;)
Best regards, lautriv.
