I'm still confused here. Let me see if I can figure it out. When HPET is enabled and you try to boot a FreeBSD CD, you receive the READ_BIG errors over and over, and it never stops. But if you disable HPET and try to boot a FreeBSD CD, it works. Once the OS is installed (with HPET disabled), if you run "kldload atapicd", you receive the following error: g_vfs_done(): acd0[READ(offset=32768, length=2048)] error 5 And if you try to mount the CD by doing: mount -t cd9660 /dev/acd0 /mnt/cd0 Then you start seeing the READ_BIG errors again, and they never stop.
