4000  (250-5000)                 Setup                  Faxback Doc. # 1444

The Tandy 4000 contains a battery-powered real-time clock CMOS RAM chip that 
stores drive and memory information about your system. You must set the memory 
of this RAM chip to your individual hardware configuration for the computer to 
function properly.

To record your hardware configuration into memory, use the Setup program on 
the system utilities diskette stored in this manual.

Because you can add memory and many optional peripherals to the Tandy 4000, 
you must run the Setup program every time you add or remove: (1) memory, (2)  
an optional diskette drive, (3) internal or external hard disk drives, or (4) 
a new video display card. You also must run the Setup program whenever you 
want to change the system time or date.

The computer retains the hardware configuration in memory until the battery 
gets weak or you change the information with the Setup program.

NOTE: With normal system use, the battery should last three years before you 
need to replace it. Because the CMOS RAM chip uses the battery only when the 
computer is turned off, the more you use the computer, the longer the battery 
lasts. Storing the computer for long periods of time shortens the life of the battery.

To run Setup, follow these steps:

1. Insert the Utilities diskette into Drive A (the upper diskette drive) with   
   the label facing up until the diskette clicks into place.

2. Move the power switch on the right side of the computer to the ON position. 
   The following prompt appears on the screen:

         BIOS ROM version xx.xx.xx
         Compatibility Software (C) 198x
         Phoenix Software Associates Ltd.,

         00640k Base Memory, 0000k Expansion
         Invalid configuration information - please run SETUP program
         Strike the F1 key to continue

The Tandy 4000 sounds one short beep when you turn it on. It sounds a long
beep or a series of short beeps as a warning signal. If the computer sounds a
warning the first time you turn it on because you have not yet run Setup.

NOTE: If, after you run Setup, the computer still sounds a warning signal and 
prompts you to run Setup when you turn it on, see the "Troubleshooting" 
section.

3. Press F1 function key. This message appears on the screen:

         Phoenix Software Asc. Ltd
         Configuration Setup Program Ver. x.x

This program is used to store system configuration information into battery 
backed memory in your computer. It is necessary to run this program when any 
memory, disk drives, or monitors are added to or removed from your system, or 
to set the battery maintained time or date.

         Press <enter> to continue...

4. Press ENTER. The next two screens describe how to set the system date and 
   time. Follow the instructions on the screens.

5. The last screen is for the hardware configuration. Because your system has
   never been set, answer no (N) at each prompt, and select the correct 
   response from the choices offered. You need to know the following
   information to complete the configuration:

     *  The diskette drive type for Drive A and B
     *  The hard disk drive types for Drives C and D
     *  System base memory.
     *  Expansion memory
     *  The primary video card.

The following two system configurations are examples of the final setup
screens for two typical Tandy 4000 configurations:

If you have only one diskette drive, no memory upgrade and a monochrome 
monitor, the setup screen should look like this when you finish making your 
selections:

         Diskette Drive A: is 1.44M
         Diskette Drive B: is NONE
         Fixed Disk Drive C: NOT INSTALLED
         Fixed Disk Drive D: NOT INSTALLED
         System Base Memory is 640K
         Expansion Memory is 0K
         Prime Video Adapter is MONOCHROME

If you have one diskette drive, a 20-megabyte hard disk, memory upgrade, 
and an 80-column color monitor, the setup screen should look like this 
when you finish your selections:

         Diskette Drive A: is 1.44M
         Diskette Drive B: is NONE
         Fixed Disk Drive C: 2
         Fixed Disk Drive D: NOT INSTALLED
         System Base Memory is 640K
         Expansion Memory is 1024K
         Prime Video Adapter is COLOR (80 COL)

NOTE: The number that you use at the Fixed Disk Drive C: prompt is the Drive 
      Type Number that you noted on the hard disk drive.

6. After you answer all the configuration questions, the following prompt 
   appears at the bottom of the screen: Are these options correct (Replay Y or 
   N then <enter>) ?

If you made an incorrect selection, type N and press ENTER to repeat the setup 
procedure. If your selections are correct, type Y. Then, press ENTER to record 
the date, time, and hardware information in the CMOS memory.

7. Now, reboot the computer under the new hardware configuration, using one of
   the following two methods. 
    (a) Press the CTRL-ALT-DEL keys simultaneously. 
    (b) Press the red Reset button on the front panel of the System Unit. The
        copyright page appears on the screen.
