Gee, sounds like a whole lot of fun. Going back to my original confusion, I had something similar happen recently with AHCI. When it's turned on, neither of my SATA DVD drives are checked for bootable devices as part of the BIOS sequence, even though they are marked as such in the BIOS.
But when I turn off AHCI and set it to IDE or SATA, the BIOS checks both for bootable discs every time it boots. ------ Brian On Sat, Oct 18, 2008 at 1:44 PM, DHSinclair <[EMAIL PROTECTED]> wrote: > JRS, Greg, Brian, > Thanks, and this is why I asked, I am trying to install Wxp and notice that > one of the very first parts/files installed seem to focus on ACPI.
