Ok.  I'm a little new to this.  How do I start troubleshooting
"a hardware configuration problem in the memory controller or
memory interface" ?

I'm using PPCBoot for a boot monitor, and VisionProbe for a JTAG
debugger.  I've run a number of RAM tests, and don't seem to have
any problems reading/writing to RAM.  What kind of thing am I
looking for?
