I've bought a HP wx9400 workstationboard - In acutallity it's a Tyan S2915-E. So my problem is: HP have flashed a special hp bios and pflash from Phoenix does not allow you to flash the vanilla tyan bios. The board has a SST49LF080A chip, so in theory flashrom should work - would be my guess. So my question is: do I just rom flashrom -p internal -w s2915.rom?, or is there anything else I have to do before flashing a phoenix bios(except a backup). furthermore I don't think the mainboard chipset is not supported - the chipset is a NVIDIA NFP3600 / NFP3050 .
