Thanks. I tried to use both the narrow and wide channels of a tyan ncr825 controller, and had problems when I set the wide drives to id's higher than 7. I got errors on the wide drive and some of the errors had a 7 in the message. I was not able to save any of the error messages because the system would just freeze up and I forgot to write them down. I have a hunch it may be related to this. > > When I was looking through the Adaptec PCI device probe I noticed you > were only using anding the HBA device ID with 0x7 and stuffing it into > SCSICONF and SCSICONF + 1.

It recognizes 825's and 875's ok. I have one of each. I can help with testing if needed. Thanks, -- Craig Shaver (craig@progroup.com) (415)390-0654 Productivity Group POB 60458 Sunnyvale, CA 94088
