i have a dell dimension xps p90 with an aha-1540cp, (plug-n-pray disabled) seagate st32550n 2gb scsi disk. no other drives or scsi devices attached. works fine. time to upgrade to a faster scsi controller. installed an aha-2940uw. the machine hangs during boot immediately after printing the disk information. called adaptec support. after changing a number of controller parameters on the aha-2940uw, each followed by a reboot. adaptec says "you have to low level format". they state that the geometry used by the aha-1540cp is not compatible with the aha-2940uw because the aha-1540cp runs the scsi bus at 5 MB/s async and the aha-2940uw want to run the scsi bus at 10 MB/s sync. this is the first time that i have heard such a recommendation. does this match anyone's experience? jmb -- Jonathan M.
