I've recently acquired an ORIGINAL IBM 8088 XTwith 256K of ram
on board (remember those? :-).

I've got a memory board with 384K of Ram but I'm having trouble 
getting the system to boot up (or pass the power-up test.)

Here's what I did:  

Plugged in memory board (after configuring it.)

Changed the dip switches on the motherboard  (switch bank 2):

						  1  2  3  4  5
				FROM 256k	  O  F  F  O  O
				TO:  640K         O  F  O  O  F
Where O=on, F=off	

On power up, I get a number, 4055201.
Anyone have an idea as to what this might be ?

By the way, with the memory board plugged in and the machine's
dip switches set for 256K, it comes up OK.  

Any help would be greatly appreciated.  Who knows, I might even offer 
this machine to the Smithsonian in a few years (along with my TRS-80 :-).
