And it gets stranger.
I found 'hwinfo' and narrowed down which bus the drive is attached to:
SysFS Device Link: /devices/pci0000:00/0000:00:14.1/ide2/2.0
Now, that PCI address is this:
00:14.1 IDE interface: ATI Technologies Inc SB700/SB800 IDE Controller
The disk is connected to SATA, and the BIOS is set to use AHCI, not
native or legacy IDE mode. Why would the drive be 'attached' to the IDE
controller and not the SATA controller? I would expect this:
00:11.0 SATA controller: ATI Technologies Inc SB700/SB800 SATA
Controller [AHCI mode]
I have a feeling something is either wrong with my BIOS, or my kernel.
I've worked around it and my system boots and operates normally,
although my CDROMS swap around making burning CDs a bit annoying, but
eh. At least the thing boots now.
