VIA always has about 2-3 revisions of their chipsets... Usually in the form of CE, CD, or CF. But rarely CF. Most of the time there is only two.
In the latest revisions Via fixes bugs and various problems in the old one. Makes you wonder about buying another via motherboard..... Thats why I like Abit, because they always wait for the 2nd revision. The Soyo KT333 motherboard uses the 2nd revision because they were having serious problems with the first. I try to never buy a VIA motherboard when it first comes out. It could spell trouble....
CE is the latest revision.
