A cpio disk written on a 9 sector disk with the option "-oBc" may be read
and written by PC/IX, Xenix all versions SysIII and SysV, and the RT/PC.
In addition, a single volume cpio disk may be interchanged between these
machines and the AT&T 7300 as follows.
The 7300 uses a disk with 8 sectors per track and the first 8 sectors
reserved. To move data from 7300=>intel use the magic "-oBc" option, and
read it as follows:
dd ibs=8*512 skip=1 </dev/rfd048ds8 | cpio -iBcdmlv
^or 1 ^^^^
|
use your favorite options
To go intel=>7300, first format the disk on the 7300, then write it using
the command:
something | cpio -oBc | dd obs=8*512 seek=1 >/dev/rfd048ds8
I have been doing a lot of Xenix/286 to 7300, and wrote a pair of programs
which will write (and format) or read multi-disk 7300 files on Xenix/286,
using standard in/out. Example:
find . -print | cpio -oBc | 7300rite /dev/rfd148ds8
will write an entire directory to a series of disks which I can read on
the 7300. The command:
7300read /dev/rfd148ds8 | cpio -iBc
will restore a series of disk written on the 7300 (to /dev/rfp021).
I'm looking at Altos now, a trifle complicated with the 8" disks and all,
I have to go through another machine.
