Here's what I'm working with:
LanParty UT nF4-D (modded to SLI & SATAII) (BIOS Date Code 2005/11/14)
AMD 3700+ San Diego
1GB (2X512) OCZ DDR500
WD Raptor 150
BFG 7600 GT OC
X-Fi Xtreme Gamer
Floppy

OC @ 2.7, 1:1 RAM Prime stable for 18+ hrs.

The system runs great, but there is an annoying message during post stating that "the boot devices have been changed" and to press F1 to continue or Delete to enter BIOS.
The Raptor is the 1st boot device, and I've changed nothing since OS install (XP Pro.) and every time I look at the BIOS settings, they are unchanged, yet I still get this message. While this wouldn't bother me much, I'm building this for my nephew and would really like to get rid of this issue. FWIW the Raptor also shows up as a removeable device in the taskbar.

I've never seen this behavior before, and the only new parts are a "SATA II Compatible" data cable for the Raptor. Any pointers? Is the OS recognizing the RAptor as a removeable device the issue? Update BIOS?

Whaddaya think, fellas? Thanks!
