[flashrom] Tyan S2915 OEM / HP xw9400 now supported

[Nils-Helge Garli Hegvik]

Hi!

I tried the same thing. I was able to write the Tyan BIOS (with the
'dd' trick). However, sincen aparently the boot block is write
protected, I get some system write errors on boot, and it takes an
awful long time to boot. But at least it boots... I tried flashing the
old xw9400 BIOS back with no luck. This is the error I get:

It also sees that I get some problems with the SATA-controllers, but
that might be related to the BIOS not functioning properly I guess.
