I've been running "FreeBSD 4.7-RELEASE" on my production system, so I tried moving the disks over and booting. Same problem. One message I found on eht web indicated that I might be able to get past the problem by disabling UltraDMA. Unfortunately: * There isn't any obvious way to do this in the AMIBIOS. * Setting hw.ata.ata_dma to 0 in /etc/sysctl.conf won't help, because (from sysctl.conf(5)): The /etc/sysctl.conf file is read in when the system goes into multi-user mode ... and the problem asserts itself while the system is still in single-user mode. So, I decided to change line 90 of /usr/src/sys/dev/ataata-disk.c to: static int ata_dma = 0; This allowed the system to boot without (apparent) error, but I'd still like to boot off a PCI-based ATA card, instead. -r -- email: rdm@cfcl.com; phone: +1 650-873-7841 http://www.cfcl.com/rdm - my home page, resume, etc. http://www.cfcl.com/Meta - The FreeBSD Browser, Meta Project, etc. http://www.ptf.com/dossier - Prime Time Freeware's DOSSIER series http://www.ptf.com/tdc - Prime Time Freeware's Darwin Collection
