Here is a script I wrote to extract the src dist, but should be able
to extract the bindist AS LONG AS cpio/sh/expr/zcat, etc exist on the
boot floppy, AND you are extracting from the other floppy drive (cause
the script needs to run commands from somewhere :)
You'll have to change some of the parameters in it.
Try it out, and mail back any comments.
NOTE: the following commands need to be on the boot volume:
sh, cd, rm, mcopy, cat, zcat, cpio, tee, expr
[
I actually wrote it from a hacked up script which took my version
of the srcdist (a tar.gzipped volume in about 10 parts, each 1.44Mb
long, and then decided ``let's add bells & whistles and post it''.
This is the 2nd post of this, the first was about late January.
