Hello misc@,

My laptop wouldn't finish booting either the i386 or amd64 ISO's from
the 4.3 CD set using an Ultrabase X6 and ultrabay slim CDRW/DVD drive.
It hung after detecting the fingerprint reader. I tried disabling
'acpidock' in the boot config (mentioned in
http://marc.info/?l=openbsd-misc&m=120976924029298&w=2), but ACPI didn't
seem to work anyway. I upgraded the system firmware to the latest
version but that didn't help.

After a few failed boots I let the boot process continue for at least
ten minutes. The console logged an 'ahci0' error message a few minutes
after the fingerprint reader line. I changed the SATA option in the BIOS
to "Compatibility Mode" from "AHCI" and both ISOs worked afterwards.

I've attached boot logs obtained through kermit over serial console for
both ISOs with and without AHCI enabled.
