Seagate HD not detected by FreeBSD

[Ulf Magnusson]

I'm trying to add a 120 GiB Seagate Barracuda (ST3120022A) HD. I've
attached it as the sole device on IDE cable 2, jumpering it as a slave
device. It is correctly detected by the BIOS as the Secondary Slave.

The drive isn't detected by FreeBSD. There's no entry for it among the
dmesg messages, and no device node gets created. I've tried disabling
UDMA on the drive, to no avail.
