   I was just given this machine by the original owner who said it worked when   
   last powered on about 16 years ago. As the title says, when powered on it   
   immediately goes to a black screen with a blinking cursor in the corner and   
   never does anything after    
   several minutes. I am very experienced with PCs but this is my first PS/2, so   
   I have no experience with these and I have no other PS/2 parts to use to   
   diagnose issues.   
      
   The system definitely looks like it has received upgrades over the years, but   
   they should all be compatible since they were working years ago.   
      
   System specifics:   
   Front of case marked PS/2 Model 90 XP 486   
   Front of internal chassis marked 8590-0H9   
   92F0161 Processor Card with DX2 50Mhz and 41G96361 ROM   
   20MB (8+4+4+4) RAM on one memory card   
   SCSI card, SCSI hard drive and SCSI CD-ROM (all disconnected for diagnostics)   
   2.88MB floppy (also disconnected for diagnostics)   
      
   I have tried the following:   
   New CR2032 battery   
   removed SCSI card and removed power from drives   
   reinserted processor card and memory card   
   tried each memory SIMM one at a time   
   flashed new ROM image to a PROM and installed that on CPU card   
   Moved J10 jumper position (was on 2-3, tried on 1-2)   
      
   None of the above changed the blinking cursor on the screen, and there are no   
   beeps. The only thing that ever changes anything is if I remove all of the   
   SIMM memory or remove the memory card entirely, it will give a 0211CZ error   
   and a blinking cursor (   
   still no beep)... which tells me it is at least able to acknowledge that the   
   RAM is there, but I have yet to see a memory test on screen at all.   
      
   Any help would be much appreciated!
