I am currently running an expansion chassis off of a Visual Commuter IBM/PC clone, containing a hard drive and mouse. (The Commuter was designed as a portable PC without expansion cards, necessitating the expansion chassis). I run MS-DOS 4.01. My 3.5" drive is a Toshiba ND3561. I purchased a 3.5" 1.4M floppy drive along with a CompatiCard II. Supposedly, the CompatiCard will peacefully coexist with the on-board primary diskette controller (which can't be disabled). However, during bootstrap, the CompatiCard software driver reports the following message: WARNING: The INT6/DRQ2 lines on the primary controller can't be disabled I cannot format either 720k or 1.4m floppies in the thing. I usually get a TRACK 0 UNUSABLE - FORMAT FAILURE on a 720k format, and a DATA OVERRUN ERROR - FORMAT FAILURE on a 1.4m format. I can read and write to a properly formatted 720k diskette, however. When I attempt a read or write on a properly formatted 1.4m diskette, I get "DATA ERROR - ABORT, RETRY, FAIL." I've tried different interrupt request lines and DMA channels (jumpered on card), getting slightly different but always bad results. I installed the card and drive on an AT clone, and it worked like a dream. Peacefully coexisted with the primary controller and all. Does anyone in net.land have any experience with either the Visual Commuter or the CompatiCard? If so, I'd appreciate any email to help me out of this bind.
