You have these on separate controllers, I bet. 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.
