>Release:        FreeBSD 4.1-RELEASE i386
>Organization:
Energy Sciences Network
>Environment:
IBM ThinkPad 600E with Utra Slimbay CD-ROM

>Description:
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

>How-To-Repeat:

Boot 4.1, 4.0, or 3.4 CD-ROM

>Fix:

Work-around by booting from floppy.
