I'm not using 2.2-anything, but the "refuses WIDE negotiation" error can be avoided by turning of WIDE negotiation with that SCSCI device (looks like 5 in your case). This is done in the Adaptec BIOS (ctrl-A at boot). Standard SCSCI, uses 8-bit parallel transfers (so does the narrow "Ultra" spec); only WIDE devices use 16-bit. It looks like both of your devices are "narrow" (the st32550W would be the wide equivalent) and so I assume they are on the same (internal) cable attached to the 50-pin (big) connector, with nothing attached to either the external 68-pin connector or the internal 68-pin (small) connector, right? And I further assume that only the last device on the cable is terminated. -- | John Lucas jlucas@jnet.vi | | Information Technology NIC Handle: JL423 | | University of the Virgin Islands (809) 693-1216 | | St. Thomas, VI 00802 http://www.jnet.vi/jlucas.html |
