- Don't put any jumpers on SS, EP, or WS. SS is Self Seek - its a test
- mode that the factories use to test the stepping mechanism of the drives
- (or so I have been told - I still don't understand what significant data
- can come from this test other than the heads move - not that they go to the
- right track, or experience track drift, just that they move. <shrug>). EP
- is Enable Parity. Don't use this as the atari does not use parity for its
- I/O streams (well, at least none of the host adapters I know of do). WS
- is Wait to Spin. Basically it is an option that makes the drive wait to spin
- up until it is "woken" up by an appropriate "wake up" signal from the SCSI
- bus. I think some Macs may have this capability (but I have never known
- a Mac (let alone any other computer, except maybe an XT :) that you would
- actually want to start the drive wakeup _after_ you start the machine as it
- generally takes longer for the drive to reach speed and initialize than it
- takes most machines to do their memory check and request info from the HD).
-
- Look, if the drive doesn't work at ID=0, in all likely hood it will
- not work with that setup. I believe the ID=4 is a fluke. Good luck anyway.
