If you screw up and apply too high of a bootstrap there is a save, move jumper to maintenance then in bios options, downclock by minus 30% and reboot. Then you can flash some more appropriate settings.

the way the overclocking on this board works, is that in BIOS, you can select from 533/800/1066/1333 FSB options, and then you can overclock in 1% intervals up to 30% from each of the base FSB options

these boards have basically no limit to overclockin, they theoretically top out at 333*130% which is 432.9mhz FSB... plenty of headroom

CPU voltage up to 1.65v, vdimm up to 2.2v, chipset up to 1.7v IIRC

Enhanced Dubug - ??? you got me? lol
Enhanced Power Slope - Drops vdroop by about 50%
Expansion Card Text - Controls whether add-in BIOS card (like SCSI/RAID cards) display init text on the screen when initializing during system boot

Can I upgrade the BIOS and make custom settings changes simultaneously?
The Intel® Integrator Toolkit does not allow you to simultaneously upgrade your PC's BIOS version and implement custom settings.

Example: Your PC currently has BIOS version P12. You create a custom .BIO file with the toolkit using a new BIOS (P14) that contains customized settings. You cannot install this custom .BIO file on your PC have the custom changes 'stick'. You must first update the BIOS to P14 and then apply the custom changes.
