I stand corrected on the label of the bus, seeing as I was intending a
generic answer to a generic statement. Check out the IWill XP-333-R
motherboard sporting an SiS735 chipset:

or
http://www.littlewhitedog.com/reviews_hardware_00034.asp
or
http://www.iwill.com.tw/xp333/page_about.htm

Front side bus speeds are 333 (not PCI) on the IWill, and the hard drive
controller is ATA133, not SCSI. As such, I conceed the name of the standard
PCI bus.

Funny, it seems like I was sounding obnoxious in return. It must be
contagious!
