No, it's probably recognized, just not set up properly.   Move your disk
onto your primary controller and do the following:

 If you get the message:
panic: Cannot mount root

At the end of the probe sequence you should either:
1. Have the line:
config kernel root on wd2

in your kernel config,
OR:

2. 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).


For the record, the IDE disk driver in FreeBSD isn't yet PIO optimized,
although a project is available that will run Mode 4 disks in Mode 4.  Let
me know if you're interested and are good at making backups.
