######UPDATE 3: THERE IS A PERSISTENT MEMORY SIZING FAILURE, not matter WHAT I insert, one of slots is failing to recognize the size and defaulting to 256MB. Also as I change RAM sticks and densities XBOW Status register failure error address MOVES slightly! Even with totally different sticks in ALL slots (no original RAM), error and sizing issues.
Now the real question, is this THE ISSUE or AN ISSUE. Would a memory sizing failure resulting in an XBOW error cause the system to stop allowing booting? Anyone know that? I mean, I'd love to solve this but I'm going to throw a tantrum if I solve the memory sizing issue and it's NOT what's preventing boot!
Okay here is my evidence. Notice the error status register address MOVES a tiny bit with each memory change!
Okay here is the POD boot info when I had JUST one interleaved bank of 512MB + 512MB = 1GB

Notice once I've placed ALL 512MB sticks in the DIMM slots I get (Believe me I popped them out and label checked, I know all my sticks were Identical from my Tezro's previous memory layout...no way this is coincidence):
** Memory sizing failure:
*** Bank 2 (512 MB) and bank 3 (256 MB) sizes differ,
*** treating them both as 256 MB
Local memory configured: 1792 MB (standard)
No matter what I insert, Bank 3 cannot determine size! If I only place in a single bank of modules (leaving bank 3 empty), I don't get a sizing error but the XBOW error remains. And since the address of the error MOVES with memory layout...it's got to be ECC status registers or something regarding memory DIMMs? Right?
Now RAM slots are normally through-hole technology, so a highly heated desoldering gun SHOULD have enough sink to reflow the pins from the underside of the memory slot. Before I do that I could look for a break using the bottom test pads (I assume they are there) and the memory slot "fingers". It will take a while.
The previous owner had an invalid memory config that the system dumbed down (I noticed this but couldn't boot so I had other issues). He had 3 x 256MB and 1 x 512MB, oddly enough my pics show he had the 512 module IN bank 3. So he use the memory failure to get all 256MB DIMMs?
Given he had this layout though...I assumed he booted at one point...so I'm worried that even though I think I'm right on this sizing failure being a cracked solder joint...he may have been booted without it this whole time! Which would mean this pre-power check error is unrelated!
Well, I have NO OTHER ERRORs to go on...I can only work with what's right in front of me. So since I know the bank with the issue, I guess I'll look into taking the mainboard out again and doing a probe/reflow on the 3rd DIMM bank.
I'm still worried that I cannot find any reference this this pre-power check error...that simple error is causing me no end of sleeplessness....
