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 :-). -- Internet: slr@caltech.edu | Voice-mail: (818) 794-6004 UUCP: elroy.jpl.nasa.gov!tybalt!slr | USmail: Box 1000, Mt.
