BIOS drive A: is disk0 <-------------------- last message seen BIOS drive B: is disk1 <-------------------- or this ... Based on Google search results: - solved by disabling SATA in BIOS - combination of IDE (ATA) and SATA disks caused a problem, disconnecting either one solved it; it could also mean a problem with hd device driver - old/buggy firmware; BIOS update solved the problem - disable ACPI, or Firewire, or USB emulation, or ... in BIOS :-) - "A wild guess could be that there's something on the RAID volume that's keeping the boot loader from working. Maybe the partition table is wrong in a subtle way? If you can get the RAID array to work *after* you boot from a FreeBSD installation CD (i.e. boot the machine without the drives, add drives later), try clearing the first megabyte of the array (dd if=/dev/zero of=/dev/yourdrive bs=1m count=1)." - "With my rocketraid somethingsomething PCI-SATA2 card with disks connected crashes the BTX loader. Connecting the disks to the internal via epia motherboard solved the problem ... I have a feeling that it might be some combinations of BTX, BIOS and RAID firmware that causes these crashes." - CC'ing John Baldwin on this, as he has knowledge of BTX's internals.
