Has anyone figured out a way to get DOSEMU to gain access to a floppy-controller
based tape drive? (e.g., a Colorado 250). I'd guess that it would be some
variation of the ports { xxx } commands in the config file, but neither my docs
nor mft.exe are very helpful in locating the tape drive.

Thanks.

You can probably forget it. I can think of several things to do to try
and get it to work, but I will bet that nothing will get it to work in
the end. Finding the right ports is just the starting point. DOS tape
software does not take well to multitasking. Even if it does work, I
would not trust the backups made. And after all that effort, probably for
nothing, it will at last be easier to just boot DOS anyway and run the
backup. :)

OK booting DOS isn't the Problem.
But how to access the Linux-Partition from DOS ?

Well one solution is making a 'tar'(or what else)-Backup from the
Linux-Partition to the DOS-Partition (if you have mounted the DOS-Partition
under Linux).

But you need the extra 'free'-Harddisk-Space on your DOS-Partition.
You could handle it for small incremental/partial Back-Ups.
But what if you need to backup the whole Linux-Partition (graeter then the
DOS-Partition)?

>: Thanks.

I'm new to Linux and didn't make efforts to install my
120MB Jumbo-Tape-Backup (it works fine under DOS) under Linux (propably ftape).
I followed discussion in this Newsgroup, but I think there is nobody out there
who has handle this problem well.
If so, let me know.
My computer is a AST DX2-66 with ... and a 120MB Jumbo-Tape attached via
Floppy-Controller. I plan to reinstall Linux with the newest
Slackware-Distribution, rather then SLS.

Suggestion of method:

1. (Under DOS) backup and verify DOS partition
2. (Under Linux) Nuke entire DOS partition
3. 'tar', or whatever, to DOS partition as much as will fit - gzip helps
here, as does backing directory trees to separate archives.
4. Boot DOS from floppy with tape sw on, use file backup to backup your
archives.
5. Repeat 2-4 as needed
6. Restore DOS partition

Not pretty, but it works. If your DOS partiton is much smaller than LInux
then the extra time to restore it is a small part of the total (if not then
you probably don't need to nuke it).

Other method is to make "image" backups of Linux partitions from DOS -
most DOS tape software seems to be able to do this - but then you can only
backup/restore whole partitions.

Some day soon I'll be able to borrow the tape drive I use for long enough
to make it work from Linux :)
