I mean these: http://amiga.resource.cx/exp/impact2000hc8
J4 - SCSI drive
J10-J12 - SCSI ID
Would you explain more about A0-A2 jumpers?
Thomas was referring to the jumpers labelled A0-A2 on the drive in your attached picture. With the jumper on A2 your drive is currently set to ID = 4. No worries about that however the
manual for the GVP card states that the drive should be set to ID = 0 (no jumpers on A0-A2) and resistor packs removed, which they are.
I'm not sure why there are SCSI ID jumpers on the GVP card. It should autoconfig as ID=7. I would just leave those jumpers empty and try it.
J4 is shown as "Autobooting" but the manual describes nothing else for it.
Maximum size, IIRC, I think is 4GB but that assumes up to date GVP ROMs and OS 3.1 or maybe even OS 3.5 minimum. Your LPS 50MB drive should be fine.
