My lastests bios for this mobo is 20.00 beta3 -

Changes:
1. Tualatin support (need some modding socket on mobo).
2. Add all frequences (66-150) in BIOS with jumpers string.
3. Tweak VIA693A functions, with qualify memory 6via85p will be 2-4 times faster (with CPU up to 800MHz faster even than i440BX mobos).
4. And some another things...
About memory. With my special bios 6via85p
can work with 256Mbit memory (256Mb/8chip), but need some modifing DIMM slot (need soldering). "Official" bioses not support 256mbit-technology memory...
