Try using a sysctl to change to pio... the BIOS is not used by FreeBSD except to actually load the kernel. However, when there's a problem with a DMA transfer, it's supposed to automatically fall back to pio mode. sysctl -w hw.atamodes=pio,pio,pio,pio If that helps, add the line: hw.atamodes=pio,pio,pio,pio to /etc/sysctl.conf That'll work if the system will at least boot. if it won't even get that far (or at least not without you falling asleep for a few hours) Try setting the flags for the ata device to 0x0000 - at least I THINK it's 0000 to disable DMA, it may be 0001... set it to whatever it isn't. :-) On the other hand, the drive could actually be bad, just in a strange way... one that doesn't actually bother a different OS... FreeBSD is pretty picky about hardware working properly. Windows often isn't. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
