Yes, well, rdisk() as well.
For real disk devices, the device name would look like this:
scsi(0)disk(0)rdisk(0)partition(1)
Now, the question is: Do you open scsi(0)disk(0)rdisk(0) or
scsi(0)disk(0)rdisk(0)partition(1)? I assume the bootloader
would actually open the former, and would then do the partition
translation on its own?
Izumi -- could you send me your code? I'd like to help out with this.
