Can I edit files on a linux boot floppy disk without installing Linux?

Hello,

I have a partitionless installation of RedHat Linux 7.0 on a FAT32 drive on
a Win2K machine.

Unfortunately, the original FAT32 drive failed. Before it failed, I was able
to copy the 2 files

redhat.img
rh-swap.img

to another FAT32 drive. I swapped the drives but booting from the boot
floppy yields

"Kernel panic: VFS: Unable to mount root fs on 07:01"

I would like to edit the boot floppy but can't find a way of doing that.
This is the only Linux machine I have. The rest of my machines are running
Windows and the boot floppy disk is not in a Windows-recognizeable format.

I have tried the Linux CD rescue option, but it doesn't see the floppy drive
device at all.

I have also tried Tom's rtbt root disk but it won't mount the floppy drive.

Is there any way that I can edit the files on the boot floppy disk?

Any help would be greatly appreciated.

Richard
