I think some of you are getting confused with Asus Mb naming system.
Asus A7V (means socket a, 7 series processor, via (V) kt 133 chipset. This one uses the 4 in 1 drivers.)
Asus A7V133 (socket a, 7 series processor (athlon, duron), via chipset kt133a. (Supports C series 133 Mhz fsb processors) This one ALSO uses the 4 in 1 and it's very important to be using the VERY NEWEST 4.31 drivers to resolve the SB Live bug with the southbridge used on this board.)
Asus A7A266 (socket a, 7 series processor, Ali Labs chipset (namely ALI Magik 1), Uses DDR ram (thus the 266 in the name). DOES NOT use Via 4 in 1 drivers.
Asus A7M266 (socket a, 7 series processor, AMD 760 (761) chipset. Supports DDR ram. DOES NOT need or use Via 4 in 1 drivers. This is the fastest board of the 4, and the most expensive/scarce.
That Letter in the middle is ALL IMPORTANT. V means VIA, A means ALI, M means AMD. Only the ones with the "V" use via chipsets and thus 4 in 1 drivers.
Asus model names are actually pretty easy once you know the code. (I.E. CUSL2 is a motherboard for P3s. CU = coppermine S = socket L = Intel chipset 2 = second board chipset from intel for this processor. )
K7V (amd slot, 7 series processor, Via chipset.)
etc, etc, etc.
Hope that clears up some confusion.
