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.

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 ) ? 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.
