I'm don't think that this is a BIOS issue. The beeps may be from FreeBSD, I
Can anyone tell me if one of the routines in the kernel beeps during a reboot?
If it is the BIOS, that beep code means that the first 64K of memory is bad,
but obviously this would seem like a strange beep code during a reboot. The
way I understand beep codes is that they should happen during a POST. But
looking at my console, I still see the stuff that you cropped out of my
original post on my screen, namely, the
cpu_reset: Stopping other CPUs
In other words, it appears that the beeps are coming from the FreeBSD 5.3
kernel, and not the BIOS. But since perhaps the cpu_reset may be somewhat
successful you may be right... The beeps could be BIOS beeps.
I know, however, that this computer always did its reboots properly when I
ran FreeBSD 4.7. So meanwhile, I have been looking at the changes to this file:
The above link shows a diff between FreeBSD 4-Stable and 5-Stable. The
differences are numerous, and some are in the middle of the cpu_reset
function which could be the problem. I may try seeing if a freebsd-hacker
might have some input. I almost began this post in the hackers list, but I
tried here first, as is my duty.
But I don't see any reason for the beeps looking into the FreeBSD kernel,
either, so I may be barking up the wrong tree.

That's true. But I wonder why it's not? My memory has never failed a test
during a POST, so failing on the reboot seems very odd. On another twist, I
happen to be buying a complete new set of memory for this machine to max it
out. I wonder if that will fix it?!
