[flashrom] HP WX9400 Workstation Mainboard flash

[Joel I. Oelsner]

Hello,
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 .
best regards
