BTX issues when booting from a USB CD-ROM

[Peter Losher]

I have a Matushita based USB CD/DVD-ROM drive that I have been using to
install FreeBSD with for the better part of the last year.  I just took
delivery yesterday of both a HP Proliant 1450 G3 and a generic 1U server
based on a Tyan Tomcat i845GV S3098 MB.

In both cases, once the USB CD-ROM started loading either 6.1 or 6.2, I
get a BTX halt:

Opening up the cases and plugging in a EIDE CD-ROM, the installer CD's
work just fine.  So it looks like perhaps there is some new BIOS
instruction set that's causing the BTX loader some pain with a USB device.

Anyone encounter similar issues recently?
