The following document should help: If you get the message: panic: Cannot mount root while booting and FreeBSD is installed on a disk on the secondary IDE controller, 1. Restart and type "1:wd(0,a)/kernel" at the Boot: prompt to start the system. 2. Rebuild your kernel, making one of the following changes to your kernel config file (NOT BOTH): a. Change the 'config' line to read: config kernel root on wd2 OR b. Rename the second disk to wd1 in the kernel config (comment out the original wd1 line and change the wd2 line to read wd1, leaving all other parameters unchanged). Install the new kernel and you're set to go. If you don't know how to build a kernel, see the FreeBSD Handbook at http://www.freebsd.org/handbook.
