A friend of mine is running esix 5.3.2-D and has a connor peripherals 100MB (cp100) scsi disk that works just fine with with his adaptec aha1540 (note no 'a' after the 1540!) rev c scsi controller board. However, he just purchased a wren IV and with this wren IV installed in the system and just after esix boots up it returns an error 16 from the aha board, which seems to indicate that a contol code has been sent either from or to the wren that the board/drive doesn't understand. What is confusing to us is that the connor seems to work flawlessly with this (albeit older) board. If we swap the aha1540 for a (newer) aha1542 board, the wren works just fine. Does anyone know why esix would work correctly with the connor cp100 and the aha1540 combination but not with the wrenIV/aha1540 combination? Is it because esix is programmed specifically for the 1542a board and not the aha1540? If that is so, why does it work with the cp100? Is anyone successfully using the aha1540 (no 'a') board with esix 5.3.2-D and any wren drive? Ideally, we would like to get by with using the aha1540 board with the wren as the boot drive (i.e., drive 0?) and the cp100 as the /usr/spool drive. This matter is complicated by not having the manuals for either the cp100 or the aha1540. In particular, the cp100 has a set of 7 jumper pins at the base of the drive, near the power leads, which we suspect are the drive id select, and three jumpers under the drive labeled "e1", "e2", and "e3". There is also a two position jumper (i.e., three pins) labeled "e4", also under the drive. We don't know the "raison d'etre" for these "e" jumpers -- probably parity enable, etc... Please respond by e-mail to "det@cimcor.mn.org" since we will not be receiving news for the next week or two. Thanks in advance, derek Ps. On a side note, i have heard rumours that the wrenIII will not always work properly with the aha1542a -- is this true? -- temporarily: derek@cimcor.MN.ORG as soon as i get my pc back: det@hawkmoon.MN.ORG
