Dear Sir,

Thank you for your kindly mail and inquiry. About the issue you
mentioned, due to the board announced, AMD Thoroughbred with FSB 333MHz
CPU was not ready, and based on VIA KT333 official design guide, it just
supports FSB 200/266MHz. Till the CPU is ready and VIA released a
engineer changing notice recently, KT333 based motherboard needs to make
H/W circuit modify to support AMD Thoroughbred CPU with FSB 333MHz.
Hence, the board in market now can not support such CPU via BIOS
updating only.
