That's my understanding but it also involves disk interfaces. I think for hot swap features, not sure.
I've gotten bitten by this twice. The most interesting was when I enabled ACPI not thinking and when I rebooted window's wouldn't boot (can't remember if it was a BSOD or a "no boot device found"). So I went back in to the BIOS and disabled ACPI but window's still refused to boot. Had to re-install. ------ Brian On Sat, Oct 18, 2008 at 2:29 AM, maccrawj <[EMAIL PROTECTED]> wrote: > Drive issues from enabling/disabling ACPI?
