IBM Netfinity 5500 M20 and FreeBSD 5.1-BETA2 - crash on install

[Dexter McNeil]

Hi,
	I'm running into the following when attempting to install the most
recent BETA .iso (downloaded last night) on an IBM Netfinity 5500 M20 box
with the following hardware:

	4 x 550MHz P-III Xeon
	2GB Ram
	AMD 79CXXX ethernet adapter on motherboard
	IBM ServeRAID 2 on motherboard - no disks attached at the moment bios
	version 4.70.17
	Intel 82559 100B/T ether in PCI slot
	Adaptec 2940UW with bios v1.34.3 w/ 6 x 18G drives attached
	Machine's BIOS set to factory defaults.

	This machine boots & runs FreeBSD 4.8 just fine. It also boots from
CDROM & installs & boots & runs FreeBSD 5.0 from CDROM. After the
announcement by Scott Long on the scsi list that the ServeRAID drivers had
been made available, I thougth I'd try to pound on them a little bit. I
work for a shop that uses quite a bit of IBM Netfinity boxen and they like
FreeBSD. Below is a screen dump (transcribed by hand - forgive the typos)
of the boot off a 5.1BETA2 CDROM. If there is anything else that I can
extract out of this, let me know.

Thanks again for a great OS!
