<< I thought that the Asus boards would work with Tulatin? >>
The TUSL2 will, but thats about it... The CUR-DLS might get another revision that will too. (with the serverworks-t chip)
Note: Abit was release BIOS for a few boards - like the be6-2 1.2 and the BX133, that will support the Coppermine-T 1.1 gig chip, so asus might do something similar. Note, the coppermine-t isn't exactly a tully, it appear on the roadmap as a 1.1gig 100mhz, .18 micron, p3...
