I'm looking for a solution that works for any machine. That is, i want to be able to boot my DOS diagnostics disks on any machine, disable AHCI during config.sys processing (as described by Jack in this thread), and reenable just before reboot. What your suggesting would only work for me if i could get the CMOS settings for every model i come across, which is many.

Perhaps the author of HDAT2 will be able to help. I'll contact him and see...
