I have Microport V/386 and a friend has SCO Xenix/386, and we were both
wondering how to make backups of the distribution floppy disks? Can you use
DISKCOPY or are they *NIX-formatted disks? If the latter, are they mountable,
or are the files tar/cpio archives? Or ???
Thanks 1e6,
Pete

The first 1 (or two, depending on which disk size) are filesystems, the rest are tar archives. If you read the manual, on of the first tasks it recommends is to BACKUP UP the distribution disks. Since SCO uses a Serialno protection there is no other backup protection involved. You CAN use diskcopy to copy ALL of the SCO distribution disks. bruce -- ========================================================================= Bruce A. McIntyre, McIntyre Designs, Inc.

You have to realize that there are two levels of formatting for magnetic media: physical formatting and logical formatting. Physical formatting is where, in the case of disks, you lay down the sector/track info. It is mainly a function of hardware[1]. The logical formatting is a function of what you are doing with the disk. Cpio archive? DOS filesystem? etc. When you do a "format", whether it be under DOS, XENIX, Microport or whatever, you are putting down the physical format. The DOS FORMAT command then goes on to put other goo on the disk, like boot and fat blocks[2]. Under unix, this is broken out in a seperate step called "mkfs". If you've got a utility which just copies the raw data on the disk, then it matters not what the logical format is, just that the physical format be understood. Under DOS you've got DISKCOPY. Under unix, there's dd. In the case of XENIX 386 on 96tpi floppies, the N1 floppy is a mountable filesystem. The rest are tar archives. But they are all boil down to 15 sector 79 track disks with goo on them. (As do DOS format DSHD floppies.) DISKCOPY or dd will work just fine. [1] Of course it is possible to do strange things, like throw on a track with am unusual number of sectors. This is the basis of some DOS copy protection schemes. [2] On hard disks, the DOS FORMAT command *only* puts down the goo. The so called low-level format lays down the physical formatting. -- Chip Rosenthal / chip@vector.Dallas.TX.US / Dallas Semiconductor / 214-450-5337

The easiest thing to do is use dd: Floppy 0 to floppy 1: dd if=/dev/fd0 of=/dev/fd1 Or, floppy 0 to HD to floppy 0: dd if=/dev/fd0 of=/tmp/disk_image dd if=/tmp/disk_image of=/dev/fd0 -- Dave Hammond daveh@marob.masa.com

I wouldn't know about microport, but on SCO Xenix there is the command: diskcp for 360K diskettes, and diskcp -96 for 1.2 meg diskettes. I don't have a 3 1/2 " disk drive so I can't help you for those.

Can you use >DISKCOPY or are they *NIX-formatted disks? If the latter, are they mountable, >or are the files tar/cpio archives? Or ??? This comes up often enough to warrant a post.... Format the destination diskette. Assuming a 1.2MB floppy: dd if=/dev/rfd096ds15 of=/tmp/disk bs=15k (Xenix) or dd if=/dev/rdsk/fd096ds15 of=/tmp/disk bs=15k (Microport) This copies the disk to a temporary file. Then, to make a dup, insert a blank formatted disk, and type: dd of=/dev/rfd096ds15 if=/tmp/disk bs=15k (Xenix) or dd of=/dev/rdsk/fd096ds15 if=/tmp/disk bs=15k (Microport) Don't forget to remove the 1.2MB file from /tmp when you're done! This works for both bootable and non-bootable Unix diskettes. -- Karl Denninger (karl@ddsw1.MCS.COM, <well-connected>!ddsw1!karl) Public Access Data Line: [+1 312 566-8911], Voice: [+1 312 566-8910] Macro Computer Solutions, Inc.
