Putting FTape on a boot disk

I Have had no problem getting ftape to work with my kernel,  and likewise
creating a boot disk, but when I try to get a boot disk with all the things
needed for FTape I run into problems. If anyone has got FTape to work off a
boot disk PLEASE!!!! email me and I will send you more details.

The problem is that, while the root disk is mounted, you can't access the
floppy streamer, since they share the same resources. You will need to use a
ram disk, unmount the disk, and you should be fine, more or less.

I am going to set up a recover disk the next time I have time, but this can
take some time...

Putting FTape on a boot disk

The following worked for me very nicely.

1. Get Slackware instalation boot and root disks.
2. Boot Linux off hard drive and mount the root floppy on /mnt.
3. Delete some files from the floppy to make room for insmod and ftape.o.
4. Copy insmod and ftape.o to /bin on the root floppy.

When you need to use ftape off the floppy, boot with the boot floppy in
A: drive.  Hit enter at the first prompt and insert the root floppy when
prompted.  You will end up with the the root mounted on ramdisk and
containing whatever was on the floppy.  Login as root and disregard            n
any messages.  CD / .  Mount your Linux partition on /mnt and load ftape.
You can now backup and restore the Linux partition.

Good luck!

        I recall reading in some ftape documentation (may have been the howto
that came with 2.02, not really sure) that to get a boot disk to work safely
with ftape, you can either use a ramdisk root fs, or use a different fdc for
the tape drive.

        That's the _only_ mention I can recall about using another fdc.  I'm
wondering if that means that a board that supports 4 floppy drives via two
floppy-cable connectors will work, or if there must physically be two
separate fdc boards, or if it's just not possible, regardless.  It would seem
to me that the last possibility is the most likely, since all fdcs use IRQ6,
whether they're physically co-located or not...  Anyone have any info on
this?

1. ftape and boot disks

Reading the notes that accompany the boot disks for slackware, I get the
impression that I should be able to access my [f]tape drive after booting
from any of the scsi boot disks.  Although I can access my [f]tape drive
when running normally (off my hard drive) I can't seem to get it to do any-
thing when I boot up from the aha1542.s (and use the text root) Slackware
boot disk.  I think I've unmounted my floppy (umount /dev/fd0 although it
still shows up in the mount table).

Has anyone done anything with tape from a boot floppy?  How do _you_
restore your boot partition from tape?

Any thoughts/comments/suggestions are most welcome.
