The rescue or boot disk should have an msdos file system on it. There
is a very handy utility called "fdmount" in the fdutils package. You
can insert a floppy disk then use fdmount to mount it as a file
system. fdmount will look for any type of file system that it can
recognize on that disk. Here is the result of my putting a rescue
floppy in fd0 and fdmount'ing it.
$ fdmount fd0
fdmount (/dev/fd0): mounted msdos 1440K-disk (readonly) on /fd0
$ ls -l /fd0
total 1374

I think they are called the major and minor device numbers. If you
look at a long listing the directory /dev you will see numbers
associated with each block device such as
/dev:
total 52
drwxr-xr-x 5 root root 19456 Sep 24 23:35 .
drwxr-xr-x 24 root root 1024 Aug 23 01:02 ..
-rwxr-xr-x 1 root root 27616 Sep 20 15:21 MAKEDEV
... lots and lots deleted
brw-rw---- 1 root floppy 2, 0 Aug 5 08:13 fd0
brw-rw---- 1 root floppy 2, 84 Aug 5 08:13 fd0u1040
IIRC the 2 and 0 on the line for fd0 are magic numbers for the kernel
to allow it to access the appropriate device driver.
