I narrowed down the problem to somewhere between August 4 and August 19 (if you want to call that narrowing down), but these commits occurred on August 22. > This motherboard only has one IDE channel... at least, only one > connector, and it's only designed to go to the CD-ROM.

At first, I believe only the secondary (ata1) IDE channel was recognized. Now both are recognized, regardless of the BIOS settings. > Sym0 was sucessfully moved from 15 to 11, to avoid sharing i'm > guessing... why didn't sym1 get moved, if that's the case? You should be able to move both of them in the system setup. You'll have to use the "lock down" feature after changing settings to keep other devices from using IRQ 15. -- Chris Dillon - cdillon@wolves.k12.mo.us - cdillon@inter-linc.net FreeBSD: The fastest and most stable server OS on the planet.
