Hangs boot with PC-9821As3 #77

Installed as the primary (only) drive in a PC-9821As3, the machine's BIOS hangs while enumerating drives to boot from.

I have a Rev2023e.

@tdaede thanks for the report. As rigid hard drive support is still only experimental/in alpha, this isn't terribly surprising. Have you tried booting from a CD?

I tried using it as a CDROM drive (the machine can't boot from it), but with the same behavior. There is a bit more info in the logs though:

I should probably note that this is on the IDE bus intended for the HDD, so not entirely sure if the BIOS would like to see a CD-ROM here.

Agreed, in that case, this is probably expected behavior
