2.88 Meg Floppy Woes

[Robert.Patrick@cs.cmu.edu]

We are running Linux on an IBM ThinkPad 750Cs with a 2.88 Meg floppy
drive.  I had no problem getting the machine to boot the Linux Slackware
2.1 kernel (1.1.59) and installing all 75 (or so) diskettes via the
setup program.  

However, when I try to use the floppy drive to move other files onto the
machine (such as the PCMCIA drivers for the modem and ethernet card), I
cannot get the floppy drive to work properly.  I have tried putting the
files on a DOS diskette and using mcopy, but I get disk I/O errors.  I
also tried using "mount" but the kernel loses its sanity when I try to
copy files to the floppy (either it says the file system is read-only or
that /dev/fd0 is not a valid mount point).

Does anyone have a clue as to how to fix this problem?  It appears to be
something wrong with the driver for the 2.88 drive since our old version
of Linux which used a hacked floppy driver which told the kernel that
the 2.88 Meg drive was really a 1.44 Meg drive did not suffer from these
problems.
