I am currently having a problem getting my Wide and narrow devices to work in harmony. Everything works great if I remove the wide device (and use narrow cabling, etc). The card is one of the origional 2940W (non-ultra, no-auto termination) with BIOS 1.16. With the wide device installed, I have all of the devices attached to the SCSI bus with the Wide Cable, and converters to go from the wide cable to the narrow devices (where applicable). The wide device is a Micropolis 4221W HDD and is the last device of the internal chain and is terminated. Using the Seperate wide/narrow connectors on the 2940 is not an option since I need to use the external connector for my JAZ/tape drive. I am currently running a kernel from 5/14. I have also tried the 6/12 SNAP with the same luck. I don't currently have SUP capability. The actual problem are timeouts (of various form - datain, dataout, etc). The SNAP fails miserably. I get a timeout on every operation. CD mount, write partition table, etc. I don't seem to see this with an old boot floppy I had from a stable back in February. Any ideas on what I can do to get this working?? Thanks
