Incompatibility: FreeBSD 4.6 scroggs Abit kd7 mobo -- reproducible!

[Mark Terribile]

(Please note that I cannot use send-pr(1) because
 FreeBSD has scrogged my motherboard and I now have
 no FreeBSD system!  Yes, the problem is reproducible,
 at about $100 the pop!)

Originator: Mark Terribile <materribile at yahoo.com>
Organization:
Confidential: No
Synopsis: FreeBSD 4.6 boot -c operations wipe Abit kd7
BIOS
Severity: Medium
Priority: Medium (as a code fix; should be High as
                    a doc fix!)
Category: i386
Class: sw-bug
Release: 4.6

Environment: A new machine with a Abit Kd7
motherboard,
 an Athlon XP 2700+ processor (NOT overclocked) and
 4x512 MB of memory.  Also an Adaptec SCSI controller,
 which does not appear to be part of the problem (see
 below).
Description: During the boot -c process, the kernel
 reports an interrupt conflict between three network
 interfaces.  (The motherboard has one on it; I had
 no others installed.)  With all three disabled,
 FreeBSD ran well for several days on the hardware.
 In attempting to find the right driver for the
 hardware I activated the one that looked likely
 (ie. not the StarLan!) (sorry, reproducing this
 costs $100 the trial, plus the time to order the
 new board) and the kernel reported an addressing
 error and panic'd.  Attempting to reboot produced
 no result; the machine was unresponsive.  It appeared
 that the motherboard BIOS was wiped or damaged.
 I followed the procedure Abit gives for resetting the
 CMOS configuration on the board, but there was no
 change in the board's behavior.
How-to-repeat:
 As above.  This procedure effectively destroys a
 motherboard!
