If you don´t get to a solution, you can post pictures of both HDs jumper explenations here and we will iron out the problem together.
I still haven't come up with a solution. I even bought a book about SCSI and couldn't find the answer.
Here are my jumper settings for each hard drive (also I am guessing at some of the jumper meanings, possibly. I can't find any info online)
Internal Hard Drive #1:
-Mac OS 9.2.2 boot disk
-Last Device in physical internal SCSI chain.
-SCSI ID 0 (I know this through SCSI Probe 100%)
-J6 Jumpers --> NO Jumpers
-J2 Jumpers --> TP from Bus & TERM Enable
Internal Hard Drive #2:
-Mac OS 7.5.5 boot disk (will format this drive once it's set up)
-in the middle of the internal physical SCSI chain
I think i have it set to SCSI ID 3 (see below)
-J6 Jumpers --> Jumper installed on ADDR 2
(I'm hoping that this makes this SCSI ID 2)
(I have also tried SCSI ID 1 Before)
-J2 Jumpers --> TP FROM BUS
(have tried with, and without this jumper)
Still starting up to a gray screen with a cursor, but no happy mac, or question mark, or anything like that.
Also, my other devices SCSI ID's are:
internal CD-ROM Drive --> SCSI ID 3
External CD Burner --> SCSI ID 4
Any Ideas? Am I missing something?
