Description Kevin Oberman 2000-08-04 22:50:02 UTC

When attempting to boot a FreeBSD CD, the boot loads off of the disc,
but the bootboot reports: Can't work out which disc we are loading from.
Guessed BIOS device 0x8b not found by probes, defaulting to disk0:

But, if I boot from floppy, the kernel has no problem locating the
CD-ROM. DMESG reports:
acd0: DVD-ROM <TOSHIBA DVD-ROM SD-C2102> at ata1-master using PIO4

Fix: 

Work-around by booting from floppy.
How-To-Repeat: 
Boot 4.1, 4.0, or 3.4 CD-ROM

Hi John,

Any ideas how to work around this?

I realize that there's nothing the loader can do, so I'm just wondering
whether there's any trick the originator might be able to pull in the
BIOS.

Ciao,
Sheldon.

Submitter says that the 4.4-RC1 CDs boot fine, so this can 
be closed. Thanks!
