See the instructions below. Two pertinent examples for which
these instructions are useful are:
1) Creating a UNIX floppy from a downloaded image for a
Support Level Supplement (SLS) which is intended for
installation with the custom(ADM) utility in Unix 3.2v4 or
OpenServer 5 operating systems, or with the pkgadd(ADM)
utility on UnixWare operating systems.
2) Creating a BTLD (boot-time loadable disk) floppy from
an SLS or other downloaded image, for use during the
installation of an SCO Operating system.
Section I
Transferring supplements from DOS to a running UNIX System:
If you have a UNIX system that is up, and the supplement you have
downloaded to your DOS system is less than 1,457,664 bytes (1.44MB),
follow the steps below to transfer the supplement from your DOS
system to your UNIX system. If you need to create a floppy for use on
a UNIX system, see section II.
1. On your DOS system, copy the file (supplement) you have
downloaded to a DOS formatted diskette.
COPY <filename> A:
Note: Because DOS only handles filenames of the 8-char.3-char format,
the supplement you downloaded may have had its name changed. For
example, the file VOL.000.000 would have its name changed to
VOL_`WPI.000. Be sure to use the DOS-assigned name.
2. Take the floppy to the running UNIX system and insert it into the
drive. At the UNIX prompt, type:
doscp a:<filename> <directory>
where filename is the name of the supplement file and directory is
the directory you want the supplement to be copied into. For example:
doscp a:VOL_`WPI.000 /tmp
Note: For UnixWare7, install and use the Skunkware MTOOLS package
from http://www.sco.com/skunkware
3. If the file is in compressed format (that is, the filename ends
in .Z) you will need to uncompress it on the UNIX system by typing:
uncompress <filename>
4. Once you have the uncompressed supplement on the UNIX system,
you can apply it to that system using the software manager (5.0 and
later). For SCO UNIX Version 4.2 and earlier, you need to install
the patch from a floppy using custom. You can create the floppy by
putting a UNIX-formatted floppy in the drive and typing:
dd if=path/filename of=/dev/fd0
The floppy created can then be used on a UNIX system in the manner
for which it was intended.
Section II
Creating a floppy on your DOS system for use your UNIX system:
If you do not have a UNIX system up and running, or the file you
have downloaded is greater than 1,457,644 bytes (that is, it will
not fit on a DOS floppy) you will need to copy the file from your
DOS system to a brand new unformatted (or UNIX-formatted) floppy
using the rawrite utility. The rawrite utility will allow you to
create a UNIX diskette from your DOS system.
Note: The rawrite utility cannot be used to transfer a
UNIX-compressed file. If the file you have downloaded is
compressed, you will need to either contact SCO to obtain
an uncompressed copy, or uncompress the file before using
rawrite to copy it to diskette. To uncompress a UNIX-compressed
file on a DOS system, you will need a utility called "gzip".
Gzip is shareware available for downloading from many Internet
sites (for example, www.pkware.com). Once gzip has been used to
uncompress the file, you can continue.
1. Download the rawrite utility (tls096.zip) from ftp.sco.com. It
is in the tls directory at ftp://ftp.sco.com/pub/TLS/tls096.zip.
2. Unzip tls096.zip using pkzip (a shareware utility available from
www.pkware.com). Once you have downloaded pkzip, type pkzip and the
utility will unzip itself, producing pkzip and pkunzip.
Please note that a 32 Bit version of RAWRITE (RAWRITE32) is
available from: http://www.duskware.com/rawrite32/
3. Unzip tls096.zip by typing:
C:\> pkunzip tls096.zip
4. This will produce the files:
RAWRITE.EXE
and
RAWRITE.DOC
5. To copy your uncompressed supplement (file) to a floppy, type:
C:\> RAWRITE
6. You will be prompted with "Enter disk image source filename:"
7. Type the name of the file to be copied to diskette.
Note: If you download a file whose name is VOL.000.000, DOS will
change the name to adhere to the 8-char.3-char filename structure.
For example, VOL_`WPI.000. Be sure to use the DOS-assigned filename.
8. After entering the source filename, you will be prompted with
"Enter target diskette drive". Enter the letter of the drive you
are using.
9. After this you will be prompted with "Please insert a formatted
diskette into drive A and press Enter". The floppy you insert must
be un-formatted or UNIX-formatted. A DOS-formatted floppy will not
work.
Press <Enter> and the floppy will be created.
10. The diskette you create can be used for application to a
UNIX system, or it can be copied onto a running UNIX system by
typing:
dd if=/dev/fd0 of=path/<filename>
Depending on which specific SCO operating system you are using,
this media file image may be used instead of the actual diskette
for installation on the system (if not a BTLD).
