Maybe I should also use "none" for the 2nd controller. Here's the way my BIOS reads: IDE Multi-sector Transfer :auto Primary IDE 32 bit Transfer :disabled Primary IDE Block Mode :disabled Primary IDE LBA Mode :slave Secondary IDE present :1 Secondary IDE 32 bit Transfer :disabled Secondary IDE Block Mode :disabled Secondary IDE LBA Mode :slave As you say, if the BIOS should *only* reflect the presence of IDE devices, then the above is wrong for the 2nd controller, and that is probably why the BIOS is choking at boot-up.

I'm still using the GENERIC kernel -- I know, I know! no guts, no glory! ;) Here's the relevant portion of my '/var/run/dmesg.boot': wdc0 at 0x1f0-0x1f7 irq 14 on isa wdc0: unit 0 (wd0): <QUANTUM LP240A GM240A01X> wd0: 234MB (479349 sectors), 723 cyls, 13 heads, 51 S/T, 512 B/S wdc0: unit 1 (wd1): <QUANTUM TRB850A> wd1: 810MB (1660176 sectors), 1647 cyls, 16 heads, 63 S/T, 512 B/S wdc1 at 0x170-0x177 irq 15 on isa wdc1: unit 0 (atapi): <NEC CD-ROM DRIVE:252/3.18>, removable, dma, iordy acd0: drive speed 1031KB/sec, 128KB cache acd0: supported read types: CD-DA acd0: Audio: play, 255 volume levels acd0: Mechanism: ejectable changer, unlocked acd0: changer slot 0 disk present acd1: changer slot 1 no disk acd2: changer slot 2 no disk acd3: changer slot 3 no disk Here's the relevant portion of my '/usr/src/sys/i386/GENERIC': # IDE controller and disks options "CMD640" # work around CMD640 chip deficiency controller wdc0 at isa? port "IO_WD1" bio irq 14 disk wd0 at wdc0 drive 0 disk wd1 at wdc0 drive 1 controller wdc1 at isa? port "IO_WD2" bio irq 15 disk wd2 at wdc1 drive 0 disk wd3 at wdc1 drive 1 # ATAPI devices options ATAPI #Enable ATAPI support for IDE bus options ATAPI_STATIC #Don't do it as an LKM device acd0 #IDE CD-ROM device wfd0 #IDE Floppy (e.g. LS-120) So... it appears that I've "pushed all the right buttons" - except for one! ;) I hate trying to mount my CD changer again until I receive advise as to how to handle a process that shows up with a "D" status in 'ps -ax', (i.e., a process that is uninterruptable) because I then can't "shutdown -h now' cleanly.
