It's only a problem switching *after* if the ahci drivers aren't in the critical dev db and you boot off them, you'll obviously get an inaccessible boot device.
For a dvd, who cares, you likely won't need the negligible perf gain from ahci, just leave it... From: Jeff Bunting [mailto:[email protected]] Sent: Thursday, April 22, 2010 10:51 AM To: NT System Admin Issues Subject: Windows 2003 AHCI woes Anyone familiar with Proliant DL180 G6 know if there is a compatible AHCI driver for Windows 2003SP2? After installing Windows on these servers, the DVD drive is not installed, apparently because the SATA controller isn't installed (unknown PCI device in device manager). I discovered that changing the SATA controller setting from AHCI to "compatible" in the BIOS makes it emulates an IDE device. I'm OK with doing this if no driver is available (I couldn't even find a mention of it on HP's G6 driver download page). Should I be concerned? From what I've gathered there may be OS problems when switching the BIOS to AHCI mode, but I haven't seen any mention about switching from AHCI to compatible mode.
