"Soyo has featured the BX chipset in all of their SY-6BA line of motherboards. The latest of these boards is the 6BA+100. It is basically the same as the 6BA+IV motherboard, with the exception of the integrated ATA 100 RAID controller. A lot of motherboards have recently jumped onto the RAID integration.
The BX is far from being something new, so you'll see a lot of companies try to spice up the life of the BX by integrating ATA 100 and RAID onto the motherboards. The BX motherboards would still reign supreme only if it had official support for a 133MHz front side bus. The only factor limiting the BX from stress free 133MHz bus operation is the lack of a 1/2 AGP ratio."
