This appendix contains pertinent files and numbers regarding the
bootstrapping procedure for \*(4B.  You should never have to
look at this appendix.  However, if there are problems in installing
the distribution on your machine, the material contained here may

Contents of the distribution tape(s)
.PP
The distribution normally consists of three 1600bpi 2400' magnetic
tapes or one 6250bpi 2400' magnetic tape.
The layout of the 1600bpi tapes is listed below.  The 6250bpi
tape is in the same order, but is only on one tape.
The first tape contains the following files on it.  All
tape files are blocked in 10 kilobytes records, except for the
first file on the first tape that has 512 byte records.

The distribution tape is made with the shell scripts located
in the directory /sys/dist.  To build a distribution tape
one must first create a mini root file system with the \fIbuildmini\fP
shell script.

The mini root file system must have enough space to hold the
files found on a floppy or cassette.

Once a mini root file system is constructed, the \fImaketape\fP
script makes a distribution tape.
