I've tried playing with the jumpers, and playing with the kernel settings (trying the tape as both unit 1 and 2). I've even tried redefining DRVS_PER_CTLR as 1 in /sys/i386/isa/fd.c, since I only have one floppy disk drive. I've tried adding another floppy disk drive, and have met with a minimal degree of success -- the kernel has actually admitted to (i.e., attach()ed) the existence of a tape drive with one of the disks I tried, but it couldn't access anything on the floppy bus with that floppy drive attached. DOS couldn't find anything on the floppy bus in that configuration either, so I assume that the second floppy was hosing the bus somehow. I've also managed to have the floppy tape attach by defining DEBUG and turning fd_debug on in fd.c. I couldn't access the tape under those circumstances either -- as I recall, the tape went to and fro for a while before I eventually received an I/O error. I've also booted the GENERIC kernel from the 950210-SNAP floppy, and it didn't find the floppy tape either (regardless of jumper settings). It's a little hard to tell, but that kernel appears to be configured for floppy tapes (_ftattach is in the kernel namelist). Can anyone tell me why I can't access the tape drive, and better yet, what I can do about it?
