         ***    NOT TO BE RESOLD    ***

This disk contains patches for many, but not all, of the
files that come on the LDOS 5.3 distribution disk. It also
includes job control language routines to assist in installing
the modifications. A program reads the encoded serial number on
the master disk and another prints the /FIX files as a group.

This set of patches uses files from the LDOS 5.3 system disk
and several files from the LDOS 5.1.4 disk. It is assumed that
you have a master disk of both systems. In addition, you need a
copy of the SOLE boot utility.

Your model I system should have two disk drives and a double
density controller board. Three drives will simplify the
modification process. If you have two drives, the files on the
PATCHES disk must be copied to an LDOS 5.1.4 system disk. If
you have three drives the PATCHES disk can be used in drive 2.

As with any patching procedure, make backup copies of all disks
before working with any of them. It's a good idea to have a new
box of disks handy to make copies of intermediate work so that
an accident during the patching procedure will not require a
new start from the beginning.

-------------------------------------------------------------

Instructions are given in steps. Follow each step in turn and
no problems should be encountered. Use your existing LDOS 5.1.4
system to make this modification. Start with a system disk
that has free space because during the procedure two files must
be added to it.

DO NOT attempt to execute any of the LDOS 5.3 files until all
steps are completed! If you do, your system will surely CRASH!

During most of the modification procedure drive 0 will contain
an LDOS 5.1.4 system disk that is controlling the computer.
Drive 1 will contain the LDOS 5.3.0 disk that is undergoing
modification.

Step 1. Copy the LDOS 5.3.0 master disk using:

          QFB :1 :0 (LDOS 5.1.4 is in drive 0)

        When prompted the LDOS 5.3.0 disk is in drive 1
        and, a blank disk is placed in drive 0

     Put the original LDOS 5.3.0 disk away and use the backup
     to make the conversion.

Step 2. Use DEBUG to copy the boot sectors from the LDOS 5.1.4
        disk to the copy of the LDOS 5.3.0 disk:

        DEBUG (E
        Press Break
        0,0,0,r,a000,6    (from disk 0)
        1,0,0,w,a000,6    (to disk 1)
        g402d
        DEBUG (OFF

Step 3. Use BACKUP/SYS:0 :1 (S,I,Q) to replace the following
        new (LDOS 5.3) files with files from LDOS 5.1:
                          SYS0/SYS
                          SYS5/SYS
                          SYS9/SYS
                          SYS11/SYS

Step 4. Update the LDOS 5.3 working master (in drive 1), if
        required, using patches given in TMQ issues through
        volume II.iii. Check the README/TXT file on your master
        disk to see which have already been applied. (Do not
        apply the date extension patches for the LDOS 5.1.4
        files). See below for other patches to be excluded.

Step 5. Modify the PATCH/CMD (LDOS 5.3) file using:

           PATCH PATCH/CMD.UTILITY:1 USING PATCH/FIX

Step 6. Move the modified PATCH/CMD file to the LDOS 5.1 system
        disk.
                KILL PATCH/CMD.RRW3:0
                COPY PATCH/CMD.UTILITY:1 :0

Step 7. Remove the protection from the PATCH/CMD file using:

          ATTRIB PATCH/CMD.UTILITY:0 (UPD=,P=ALL)

Step 8. Apply the patches to the system files, basic files and
        utility files with the /JCL files on the PATCHES disk.

            DO SYSPATCH
            DO BASPATCH
            DO UTLPATCH

Step 9. Move the TED/CMD file to the LDOS 5.1.4 system disk.

            COPY TED/CMD.UTILITY:1 :0

STEP 10 Reformat the boot track on the modified LDOS 5.3 disk
        with the SOLE utility.

            SOLE2 :1

Step 11 Copy a CONFIG/SYS.CCC file to the new disk. Include
        the RDUBL or PDUBL disk driver; if you use a blinking
        cursor or the midnight date update option include them
        in the configuration also.

Step 12 Make a backup of the new disk, boot it up and
        KILL TED/CMD.UTILITY

Step 13 Run SOLE1 :0 on the LDOS 5.3.a disk.

Step 14 Copy TED back from the LDOS 5.1.4 disk to the LDOS 5.3.a

Step 15 Backup the modified LDOS 5.3 disk and use it.

       ***PATCH EXCEPTIONS ***

Do not apply the following patches from TMQ, they are either,
not needed, or will not work on the model I.

PRFLTB/FIX - VI.iii ... (Remove it if it has been applied)
SYS0A/FIX  - VI.iii ... (SYS0/SYS [5.3] is not used)
SYS7C/FIX  - VI.iii ... (SMOOTH is not supported)
SYS7D/FIX  - VI.iii ... (BLINK of [5.1.4] used)
SYS5A/FIX  - VI.iv  ... (SYS5/SYS of [5.1.4] is used)

--------------------------------------------------------------
NOTES:

1. The AFLG$ patches are not anticipated by the /FIX files. If
   you plan to install this option, apply it last. Remember the
   unused space in SYS0/SYS (5.3) is different than that of
   SYS0/SYS (5.1)

2. This README2 file was created using a test disk modified
   with these /FIX files.

3. To determine the serial number of your LDOS 5.3.0 master
   disk, place an umpatched copy of the master disk in a
   drive and type:   SERNUM
   You should see a series of characters such as "TC0.....".

4. If you have a single drive system you will experience the
   tedium of transferring and patching one file at a time,
   good luck.

5. If you have a single density only system you will need a
   friend to convert your new LDOS disk since it comes in
   double density.

---------------------------------------------------------------
==> If you have trouble:

    - Be sure that the BOOT/SYS file is the same as on the
      LDOS 5.1.4 disk.

    - Examine the troublesome file with FED and compare with
      the /FIX files to analyze the problem.

    - The file you are having trouble with may not have a /FIX
      file. They  are not provided for every program included
      with LDOS 5.3. You may need to develop your own patch.

    - If all else fails write to me at the address given in this      file. I will try to help.

      End of Readme too.
