XThis shar file, in addition to the kernel object files (kern.cpio.Z), and
Xconf.shar (by Mark Dapoz) will help those who want to create a 3.51m
Xfloppy UNIX that has the tape driver (floppy tape) compiled in, and 
Xinitialized.
X
XBasically included here are:
X
X-rw-r--r--   1 lenny    icus         1689 Jul 22 23:16 README.funix
X-rw-r--r--   1 lenny    icus          421 Jul 22 23:07 floppyunix.mk
X-rw-r--r--   1 lenny    icus         1855 Jul 22 23:03 conf.c.patch
X-rw-r--r--   1 lenny    icus          496 Jul 22 23:08 init.h.patch
X
XPatch <sys/init.h> with init.h.patch, and patch Mark's conf.c with 
Xconf.c.patch.
X
XThen type:
X
X# make -f floppyunix.mk
X
XIt will create a, stripped kernel that when booted will have the tape
Xdriver loaded and usable:
X
X-rwxr-xr-x   1 root     root       144852 Jul 22 21:18 fpUNIX3.51m.tp
X
XCopy this kernel to a floppy:
X
X# fdfmt10.sl				# format a floppy with the silent loader
X# mount /dev/fp021 /mnt			# mount the floppy
X# cp fpUNIX3.51m.tp /mnt		# copy the unix to the floppy
X# ln /mnt/fpUNIX3.51m.tp /mnt/unix	# link it to unix
X# dismount -f
X
XThe tape driver is at major number 9, so you need to do this on the
Xfloppy filesystem:
X
X# fpcp					# copy the floppy filesystem, disk 3 
X
X# mount /dev/fp021 /mnt
X# cp /etc/fsck /mnt/etc
X# mknod /mnt/dev/rft0 c 9 0
X# mknod /mnt/dev/rft3 c 9 3
X# dismount -f
X
XFor those who want to create a floppy unix boot, and floppy filesystem
Xpair, for tape backup recovery, this will help.
