SOYO has released a BIOS update for the P4S-ULTRA that upgades it from 400 MHz to 533 WOOHOO it now supports all new P4's
Tom's hardware also made a mistake in the review as the Highpoint controller supports ATA-133 (not that there is a big difference in performance) They could have also mentioned the fact that that MB has 5.1 channel audio s well as optical outs which is pretty rare on a system with onboard sound
More aboutsoyo ultra
The bios upgrade p4sx2ba4.bin is for the dragon lite only with sis 645, not the sis 645dx board.
Actualy it is NOT only for the Dragon Lite, it also supports the P4S-ULTRA Dragon (RAID) motherboard
