I forgot that all my drives are on a secondary power supply. I turn it on about a minute before I power up the CPU. Oops. DLP

I missed the first part of this thread, but it looks suspiciously like the behavior of my 1542B/ Seagate 296N combination under Xenix 2.3.2. On the initial power-up sequencing, the Adaptec will poll for devices before the Seagate has finished it's recalibration. After about ten seconds of silence, the ST296N will restart what sounds like it's power-on self test, and the 1542B will then report it as Drive C and continue. Come to think of it, this is not OS specific, because it does this when I run it under DOS as well. -- Tim Bowser ("Strikemaster") | Standard | mailrus!sharkey!clmqt!strike Enterprise Information System | Disclaimer | strike@clmqt.marquette.Mi.US Marquette, Mi.
