The top jumper is for the "serial port" (?) and the middle is for "diagnostics". Neither is used in operation. The bottom jumper is the parity enable strap (jumper to enable). The second column is the buffer disconnect selection. This selects the number of bytes that can be sent over the SCSI bus during a single transfer. All the jumpers in this column are used, aand they are designated, from top to bottom as CF2, CF1 and CF0. Here's how it works: buffer size 2k 4k 6k 8k 12k 16k 24k 32k CF2 out out out out in in in in CF1 out out in in out out in in CF0 out in out in out in out in Standard config is 16k. As an aside, does anyone know if the SCO Unix drivers understand these settings, and what the effect of increasing or decreasing the buffer size is? The last column is the drive ID. All straps are used and they are designated, top to bottom, ID2, ID1 and ID0. drive ID 0 1 2 3 4 5 6 7 ID2 out out out out in in in in ID1 out out in in out out in in ID0 out in out in out in out in The default is 0.
