Message-ID: <1991Jun20.170531.23159@newserve.cc.binghamton.edu> Date: 20 Jun 91 17:05:31 GMT Sender: chris@zork (Chris Peck) Organization: SUNY Binghamton Lines: 33 Nntp-Posting-Host: zork.cc.binghamton.edu Well, I bought an old C= 2052 (?) ram card for my A2000 yesterday (not sure of the number - it holds a total of 2 Meg RAM only). It's fully populated to 2Meg. I've had an older GVP SCSI/RAM controller (can hold 0, 1 or 2 Meg RAM - it has 1 Meg on it, the jumpers are set right - I've been using this card for quite awhile now, with no problems, until now). Also, there's a Quantum 105S connected to this (has been working fine since I bought it 2-3 weeks ago). Let's see, the motherboard is Rev 4.3 (so the MB has 512K chip & 512K Fast RAM) and it's jumpered to NOT get TICK from the power supply (non commodore, 200 watt Power One PS)... Also, I have 1 floppy drive. Here's the problem: After I put the 2052 RAM card in my A2000, I powered it on and got a read error on my hard drive. I turned it off, removed the 2052 and powered on again - it booted fine. I put the card back in a different slot and powered on, same error on hard drive, so, I powered off waited a minute & powered on - same error, so I cycled power one more time and bingo - it booted fine! I ran QBTools & DR.AMI on my hard drive in search of bad blocks - none were found. I ran DR. AMI on the 2052 RAM card - no problem! The A2000 see's all 4 Meg RAM. SO I figured it was a weird one. The next day, I powered on the A2000 - error on hard drive. I cycled power again and the 3rd time it booted up with no errors. Same thing this AM (3rd time a charm). Well, I'm stumped! I noticed 2 jumpers on the 2052 (J1 & J2) but have no docs on this card (neither does my local dealer). Does anyone know what these jumpers are for? Could they help solve my problem? Anyone wish to hazard a guess as to why I get an error from my WorkBench(Hard drive) the first 2 power ons but not the 3rd? Any suggestions (other than to sell the 2052 card?)??? -thanks chris -- chris@zork.cc.binghamton.edu Chris Peck chris@bingvaxu.cc.binghamton.edu SUNY Binghamton, NY chris@bingvaxa.bitnet --"Any opinions expressed above are mine, ALL MINE!"--
