Hi, I have two identical (model/size/etc.) hard drives in a computer, both of which are recognized by the PC's BIOS, both of which are listed in dmesg as ad0 and ad1, respectively, and both of which appear as /dev/ad0 and /dev/ad1. One is master, one is slave. The slave (ad1) is never mounted. My goal was to install FreeBSD and set up apps for a user on the 'master' drive (ad0), then 'image' the drive over to ad1 (to produce backup media for the project) using the following command: dd if=/dev/ad0 of=/dev/ad1 bs=512 So far, so good, everything works great. dd reports that everything went smoothly. Then I attempt to boot off the that slave drive, after performing the following steps to make what was once ad1 is now the primary ad0 drive: * disengaged the drive data cable from ad0 * set ad1's jumper to a single drive * changed the bios to recognize only one drive When I try to boot off what was once the slave drive (ad1), however, I get errors that /boot/loader and /kernel can't be found. >> FreeBSD/i386 BOOT Default: 0:ad(0,a)/kernel boot: Not ufs No /kernel Does anybody have any thoughts on what I might have missed? Google and newsgroup searches have not produced an answer that's helpful. Of course, I hope I haven't committed some remedial error and wasted your time with this post. Thanks, G. Sherman
