I'm working on upgrading a server, and have encountered a frustrating problem.
This server has dual IDE controllers on the motherboard, but they're slow --
33 MHz max. So, I bought an Promise PCI Ultra100 controller and plugged it
into a PCI slot. I then took the boot drive and plugged it into the new
controller. Once I did this and reconfigured the BIOS, the system would 
load the kernel and get partway through the boot sequence but then
freeze up. From the messages on the screen, it appears that, even though it 
had properly loaded the kernel from the hard drive, it couldn't find its
root filesystem later on in the boot sequence and so could not boot up.

I changed /etc/fstab before the shift so that the system would know
that /dev/ad4s1a was to be root, etc.; however, there are apparently
other things to shift as well. What did I miss?
