Marlene, Larry and Bob Rakosky have been doing there best to show me what I am doing wrong, but I still have trouble accessing my scsi drive when two screens are showing. The scsi gives me a read/write error most every time it is accessed with 2 screens showing, but not one. I put slow mem last in my startup-sequence before anything else, I have the latest driver. Any other suggestions? My environment is an A2000, a 2090, 3 meg ( one asdg 2mg board- recent addition, no difference ), 1 miniscribe 8425 ( a 20 meg st506 type drive ) as the system disk, 1 ST251N ( a 40 meg scsi drive ), two 3.5 floppies ( one external ) and thats all. question: to any one with the ST251N how many cyl did you say you had at prep time? Did you say 820 or 807 or what. I said 820 first prep and then at format time it wasnt able to format past 807. I re-preped with the cyls at 807 and it formated clean. Am I wrong ?? My mountlist is the default RES2: entry for the scsi with 20 buffers a interleave of 0, 4 surfaces, 17 blocks per track, lowcyl = 0 highcyl = 1, bufmemtype I changed to 4 but no diff, reserved = 2, unit = 3. See anything wrong? Lets hope its me and not a problem with the 2090. Unless another new driver fixes it. Paul Montgomery
