I'll make it a point to check for that. The wording on different bios' can often be confusing. I've seen ahci mode referred to on one board as "native mode" but on a different system it's referred to as "enhanced" (where "normal" is emulation), and other oddisims. Double check your mobo manual and find the chapter that talks about it. >> You'll also almost certainly want to disable any motherboard-based raid >> options too, as they tend to be complete crap. > > OK. I never use RAID in any form anyway, so it probably is already > disabled, but I'll make a point to double check. A word of warning: Not all boards do things *right*, so it pays to test. I've encountered systems where you get gpt checksum errors and stuff when ahci is on because the board masks part of the drive for its fake-raid stuff even if you have fake-raid supposedly turned off. ______________________________________ it has a certain smooth-brained appeal
