We are attempting to install a PRIAM 325Mb (formatted) hard disk in our AT&T 6386 and are having a few problems. We are using a controller board from Adaptec that has both hard disk and floppy controller capabilities. Normally, this would be fine, but the 6386 has its floppy controller on the mother board, and as of yet, we have been unable to disable either it or the floppy controller on the controller board. My question is, does anyone know if it is possible to disable the floppy controller on the mother board or if Adaptec makes a control- ler board without the floppy controller? We've tried contacting both AT&T and Adaptec, but niether have been of much help, yet. Any response would be much appreciated ... Thanks Deloy Johnson WORK : (616) 452-1191 HOME : (616) 538-6055 email: ...!killer!wybbs!dpj

Unfortunately, nowhere can I find a description of what they do, why they are there, and what would happen if you monkeyed with them. This appears to be the extent of the official documentation on the matter (unless I can't find the right page). Anyone else out there know something that we don't???? Mike Cripps mtuxo!mcripps
