The hardware includes Motherboard: ECS P4S5MG/651+, AMI BIOS, 2.4 GHz P4, 1 GB DDR RAM Primary IDE: Master: 40 GB Western Digital HD Slave: 80 GB IBM HD Secondary IDE: Master: No-name DVD-ROM Slave: No-name (Optirite?) CD-RW, 40x I can boot the installation CD and things seem normal until I get ad0: READ command timeout tag=0 serv=0 - resetting ata0: resetting devices .. and nothing more. I thought this was related to the ATAPI problems discussed on the list off and on in recent months, but the el cheapo CD and DVD drives seem to be working fine while the hard disks are causing problems. I've checked the jumpers carefully, swapped out the cable, tweaked everything in the BIOS that looks remotely related, and tried each disk alone with no change. I tried to install NetBSD 1.6 from CD with similar results, but the error message grumbled about DMA. Aha, said I, back to the FreeBSD archives...at length I found that pausing the loader and entering set hw.ata.ata_dma=0 boot will let the installation proceed, but it looks, er, drastic. For what it's worth, MS Windows XP Pro installs without a hitch. Sigh. Can anyone shed some light on this behavior or suggest a proper fix?
