Re: SCSI Manager 4.3 and the Q900/950?
Derek Morton [EMAIL PROTECTED] wrote: A SCSI conflict will (should) only happen if both devices exist on the same physical bus. Since the 900 / 950 has two physical busses, there should be no conflict, but the internal bus devices take precedence over the external bus devices (until 4.3 loads). I mentioned in an earlier email that I will do some testing this weekend to verify whether or not this is the case (along with the Jackhammer having 4.3 onboard idea). Hi Derek, I've tried such a test (of having the same ID for two devices on ext. and int. buses). It almost works! :-) I've set my ext. CD-ROM drive from ID5 to the ID1, while one of internal hard disks hooked to the int. bus is also at ID1. The system (MacOS v7.6.1) booted just fine, and both HDD and CD-ROM are accessible, but any attempt to launch some diagnostic utility (such as 'Mt.Everything', 'Peripheral View' etc.) hangs the machine completely. It seems that 'hardware-wise', it's OK to have both buses fully populated with devices, but most of standard software will go crazy looking at it! :-) I really cannot imagine needing more than seven SCSI devices... CD-ROM, M.O., Printer, Scanner... This still leaves three for hard drives (and I doubt many people are running SCSI printers). What else is there? Perhaps I just don't have enough toys! :-) In my case, I have five HDDs, CD-ROM and the scanner, so adding of tape, ZIP or MO drive can be done by removal of existing device only...

Re: SCSI Manager 4.3 and the Q900/950?
It seems that 'hardware-wise', it's OK to have both buses fully populated with devices, but most of standard software will go crazy looking at it! :-) The machine was designed to accommodate five internal HDs, and at least in the WGS 95 incarnation it will accommodate a CD-ROM and a tape as well. The five HDs are designated A, B, C, D and E, and each one has its own SCSI ID switch. So also does the tape drive. The CD-ROM is semi-permanently set as SCSI ID=3. It is possible to install the five drive shelf on a Q950, although the standard Q SCSI cable is incorrect for this accessory. It is also possible to install the WGS 95's CD-ROM and tape bezels on a Q, but the same comment as to the SCSI cable applies. A maxed-out Q has all possible SCSI IDs in use: the CD-ROM is 3; the tape is usually 6 (switchable); the two basic HDs are 0 and 1 (switchable); the three additional HDs are usually 2, 4 and 5 (switchable); the Mac is always 7. With a properly configured 7.6.1 system (or perhaps with the SCSI Manager 4.3 extension taken from 7.5) there should be no conflicts after startup is complete. Application software doesn't know one SCSI bus (0, e.g.) from another (1, e.g.). System software and utilities released concurrently or after 7.6.1 will know one bus from the other. 7.6.1 was used on PCI PowerMacs, and except for the 7200 these have two SCSI buses, just as the Q does. -- Quadlist is sponsored by http://lowendmac.com/ and...
