The ABIT board will give you the BIOS option to 'LOAD FAIL-SAFE DEFAULTS' or to 'LOAD OPTOMIZED DEFAULTS'. The fail-safe will most likely set you up as an XP1500+ at 100FSB, and the optomized will set you up as the highest level the board auto-detection recognizes. PF10 to save this setting and re-enter BIOS. Study the first BIOS entry to see what your starting point is. If you need to 'FLASH' the BIOS, perform it EXACTLY as the ABIT web-site tells you. Download the Award Flash.EXE program and the newest BIOS revision for your board to a clean formatted floppy, and do the re-boot. DO NOT INTERUPT THE PROGRAM FLASH ! It will do everything automatically. When you re-enter the BIOS you will see the added parameters for the CPU's. Then you can Tweak the BIOS to set your phasers to stun.
I wouldn't be suprised if you could run your XP2000+ as a 2100+/2200+ as you can get really aggressive with these boards without resorting to any unlocking. Some of the ABIT boards when coupled with certain video cards will let you 'loan' memory across the hard drive, I have an XP1800+ with a Prophet 4000XT 64MB, with 768MB
