TANDY  1000 RLX B  (250-1452B)      Installation        Faxback Doc. # 1816

First we will discuss the correct procedure for installing MS-DOS 6.0 on a
TANDY 1000 RLXB from scratch.  (See Solution #1).  Next, we will discuss
the variables connected with MS-DOS 6.0 and a 1000 RLXB that failed the
automated setup procedure.  (See Discussion/Solution #2.)

NOTE: DO NOT RUN THE MS-DOS 6.0 AUTOMATED SETUP PROCEDURE ON A 1000 RLXB.

SOLUTION #1:

Fix #1: (INSTALLING MS-DOS 6.0 ON A 1000 RLXB FROM SCRATCH).

1. Boot the 1000 RLXB with the MS-DOS 6.0 Disk #1.in floppy drive A:.

2. At the Setup Screen, push F3 twice.

3. At the A:\> prompt, type SYS C: and press <ENTER>  After some time you
   will get a system transferred message and then an A:\> prompt.

4. At the A:\> prompt, type C: then press <ENTER>.

5. At the C:\> prompt, type A:SETUP /Q then press <ENTER>.

NOTE: The /Q switch causes setup to uncompress and copy MS-DOS 6.0 files
      directly to your hard drive.

6. MS-DOS 6.0 will prompt you to insert diskettes as needed.  Follow the
   instructions on the screen until all four diskettes have been copied to
   the hard drive.  Setup will prompt you to press <ENTER> when the
   procedure is complete.  Before you press <ENTER> take MS-DOS 6.0
   diskette #4 out of the floppy drive, and put in MS-DOS 6.0 diskette #1.
   Then press <ENTER>.  At the C:\> prompt, remove the MS-DOS 6.0 #1 floppy
   diskette from drive A:

7. At the C:\> prompt, press CTRL+ALT+DEL to boot MS-DOS 6.0.  At this
   point you will be up and running MS-DOS 6.0.

NOTE: When you SYS a hard drive with MS-DOS 6.0, the system files are no
      longer IBMBIO.COM AND IBMDOS.COM.  They are IO.SYS, MSDOS.SYS, and
      DBLSPACE.BIN.  After you finish installing MS-DOS 6.0, use the ATTRIB
      command to unhide the IBMBIO.COM AND IBMDOS.COM files.  Then delete
      them.  The syntax is: At the C:\> prompt, type ATTRIB -A -R -S -H
      IBM*.COM then press <ENTER>. At the C:\> prompt, type DEL IBM*.COM
      then press <ENTER>.
      This will free up 70,904 bytes of hard drive space.

DISCUSSION #2

If you installed MS-DOS 6.0 and got a hard drive write error, then pushed
<ENTER> to continue, the 1000 RLXB will reboot.  After you get the BIOS ROM
message, you will get a message telling you to insert your uninstall
diskette.  If the uninstall diskette is corrupt or the automated Setup
procedure has been run more than once, this message will never go away.
The automated setup could not finish writing to the hard drive, so the boot
track on the hard drive is corrupt.  It appears to be trying to write to
the ROM.  Since You can not low level format IDE Hard Drives, we can do an
FDISK and use the /MBR switch.  The /MBR switch will reset the boot sector
of the hard drive to its original condition.  MBR is the acronym for Master
Boot Record.

Fix #2 (INSTALLING MS-DOS 6.0 WHEN THE UNINSTALL DISKETTE WON'T WORK).

1. Boot the 1000 RLXB with the MS-DOS 6.0 Disk #1.in floppy drive A:.

2. At the Setup Screen, push F3 twice.

3. At the A:\> prompt, type, FDISK /MBR then press <ENTER>.

4. At the A:\> prompt, type, SYS C: then press <ENTER>.  After some time
   you will get a System Transferred message.  After which you will get an
   A:\> prompt.

5. At the A:\> prompt, type C: then press <ENTER>.

6. At the C:\> prompt, type A:SETUP /Q then press <ENTER>.

NOTE: The /Q switch causes setup to uncompress and copy MS-DOS 6.0 files
      directly to your hard drive.

7. MS-DOS 6.0 will prompt you to insert diskettes as needed.  Follow the
   instructions on the screen until all four diskettes have been copied to
   the hard drive.  Setup will prompt you to press <ENTER> when the
   procedure is complete.  Before you press <ENTER> take MS-DOS 6.0
   diskette #4 out of the floppy drive, and put in MS-DOS 6.0 diskette #1.
   Then press <ENTER>.  At the C:\> prompt, remove the MS-DOS 6.0 #1 floppy
   diskette from drive A:

8. At the C:\> prompt, press CTRL+ALT+DEL to reboot MS-DOS 6.0.  At this
   point you will be up and running MS-DOS 6.0.
