This article is from the comp.sys.acorn FAQ, by Paul Vigay with numerous contributions by others.
Most of the modern drives have this information nicely on a label on the top of the drive, but some of the earlier ones don't. There follows a list of drive settings for some of the packaged drives.

Link connectors are on the front of the drive, the narrower end that doesn't have the cables coming in, next to the activity light connector (which is missing on Risc PC Drives - it's on the motherboard)
It should also be noted that if you need an extra linker don't expect it to have been provided (notably on the CF3008E, the 80M drive in the A4000 & A5000.)
(Details translated from table by Dave Walker, as published in Acorn User Sept 95. Not all permutations have been tested, and we ain't promising!)
