I stuffed these into an old chassis, adding a 500 W power supply and a pair of 512 MB DDR DIMMs. After walking through the configuration (accepting "Optimal Settings" for everything), I tried booting up the machine on an IDE drive that was loaded with FreeBSD and had been used most recently with a 200 MHz Pentium II. The boot sequence proceeded without problems for quite a while, checking devices, etc. Then, however, it halted with a pair of nastygrams: ad0: READ command timeout tag=0 serv=0 resetting ata0: resetting devices I tried putting the ATA drive and the CDROM on separate cables, but that didn't seem to help. My suspicion is that the drive is too slow for the ATA controller, but I don't see any way to compensate for this.
