Ahh, and a review

Also has bus speeds options 100-200 MHz, and multi adjust is done by dipswitch. Here's the big thing - 1/5 PCI divider kicks in at 150 bus! The BIOS even says 1/6 at 200 to keep PCI at 33 MHz. There are benches at 150 and the reviewer got to 166 using a softFSB-like proggie that came with the board, but there's no mention of trying to boot at 166 MHz bus.
