Daily dose of weird computing
I finally finished my "news" AMD system, and decided to boot Linux on my old P4 system. As soon as I did, though; something very odd happened. The speaker started going off like a klaxon! At first, I thought perhaps it was the thermal alarm. I have moved the box around a bit, so it was possible that the heat sink had come loose. Nope - still firm, and the BIOS reports normal temps for everything. Then, I restarted a few times and noticed that as soon as the system began the initial boot, the klaxon started. The OS loads normally (I've tried Centos 5, Fedora 7, and FreeBSD 6.3) and I could login - albeit with a very loud noise. Even stranger, as soon as the system reboots, the noise stops instantly. (the moment the screen goes black) I'm not sure what is causing it. I have the same model Adaptec 29160 SCSI controller as in the original system, and much of the other hardware is identical. I did migrate my AGP card, and replace it with an older 5700 board, but that board was in this box to start with. I also took my 3Com 3C905TX-C NIC (it still performs better than the onboard LAN) and replaced it with a dual Intel EtherExpress Pro 10/100. All in all, a real head scratcher. The POST code is 0x0E when it starts. The machine is a 2GHz P4 on an Abit BL7-RAID mainboard (socket 478). The RAM is (more or less) maxed out at 1.5GB. Anyone seen anything like this?
