The root device is not expected to be on wd2. You should be able to specify wd2 at the boot prompt; if that doesn't work, you will need to (temporarily) replug your drives so that FreeBSD can come up, and you need to rebuild a kernel. Here is the line from your current kernel (compiled with GENERIC): ============================================================================== config kernel root on wd0 ============================================================================== Here is the LINT description (/sys/i386/conf/LINT): ============================================================================== # # This directive defines a number of things: # - The compiled kernel is to be called `kernel' # - The root filesystem might be on partition wd0a # - Crash dumps will be written to wd0b, if possible. Specifying the # dump device here is not recommended. Use dumpon(8). # config kernel root on wd0 dumps on wd0 ============================================================================== I *think* that you can say "root on wd2", and it will work. If not, you will need to change machdep.c to hard code 0x82, or set up the drive as the slave on the primary controller.
