Ideally something exposed via IPMI that could be set via "ipmitool raw" or similar.

It seems reasonable that you could change a BIOS setting via a script somehow & have it take effect on reboot. I know we do that with core count settings on some of our clusters. -----Original Message----- From: Allen, Benjamin S.

We're hoping to provide the users some self-service ability to change the mode and have it in effect on reboot. Thanks, Ben
