Hi there all,
I have another data point, since I upgraded the bios on my Tyan S2915 MB, using a hacked CD and DR-DOS. After a cold boot, using the svn version of flashrom , the new bios (v401) made no difference to the chip detection problem.
I mention this, since the board had the oldest version of the bios and since the PCI routines had a bug (video cards change address every boot), there was an outside chance that my board would not respond like the Tyan representative's, since the bios was older.
My machine has 8 GB of memory, and I qm running a 32 bit version of 2.6.31.12-0.1-pae
Cheers
PHiL
