Hi all,
I'm interested in trying to get more than two floppy drives into the same PC.
I don't have a four-drive floppy controller, but I have found a generic two-drive ISA card that can operate as a secondary floppy controller.
Unfortunately I'm not having much luck getting DOS to see the drives on the secondary controller. There's no BIOS on it, which leaves me with options like SDRIVE.SYS. SDRIVE manages to switch the motor on for the fourth drive, but only when a third drive is connected and that's as far as it gets. The drive motor never goes off again and the first two floppies on the primary controller stop working (whether I tell SDRIVE to handle the primary drives or not.)
I have read that people with dedicated four-drive controllers have had much more success when using cards with their own dedicated BIOS, so I am wondering whether one of these BIOSes may work with a generic floppy controller operating at the secondary port address.
Does anyone know whether BIOS images from these controllers are available online? I know there are a lot of motherboard BIOSes out there but I don't really know where to start looking for floppy controller BIOS images.
Thanks for any info!
