so this is ddr1/pc3200, right?

I think that bios version is quite out of date:

> CPU0 MemClk 200MHz Tcl=3.0 Trc=3 Tras=8 Trp=3

200 gets doubled (ddr) to 400 mega-transfers per second, which is pc3200.

> CPU1 MemClk 100MHz Tcl=??? Trc=0 Tras=Trp=0

this indicates that the memory isn't detected, I think.  I think you 
have just two dimms installed, which would agree.

that sounds like the device is requiring its PCI resources 
mapped to physical addresses occupied by memory.  I would guess 
that there are bios options that would work around this.  but 
I'd update the bios first.

nah, the ram sounds fine.  the issue is getting it to boot into the 
flash image, I think.
