Most BIOS seem to use BEEP beep beep beep for video or memory > errors, but check and see. I'm don't think that this is a BIOS issue. The beeps may be from FreeBSD, I believe. 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: http://fxr.watson.org/fxr/diff/i386/i386/vm_machdep.c?v=RELENG4;diffvar=v;diffval=RELENG5 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. > BN> I don't know how long I've waited for the system to reboot, but so far > BN> it hasn't. > > If the BIOS is unhappy, it's not going to reboot. > 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?! Billy
