I've heard of a few success stories and no failures with a BIOS flash to 1016. ASUS doesn't say it on their site (Only Rev 2.0 or later supposedly), but I did flash my BIOS to 1016 and the 166Mhz option is there. It will be a 3000+ Barton so I'm hoping it will work alright. Oh and technically the FSB is 166Mhz and the CPU clock just runs at double that (times whatever multiplier) right? Thanks!
