PC-DOS supplies a driver for disks A and B, at least, and any installable drivers would be assigned letters higher than that. The only way I can see to do this would be to capture the INT 21 Dos calls. This isn't as far-fetched as it seems - the PC-DOS ASSIGN command does this. Given that, one could install a device driver as, say, drive D (after the fixed disk), and make it LOOK like drive B with the assign command.
