Maintenance and Service Guide 4-21 Head Select Format Menu The Head Select selection verifies that each head of the fixed disk drive can be accessed and is functional. The Format Menu selection provides two format program options and two formatting features for special applications only. The Format Menu allows you to run the following tests selectively on each physical drive present.
PAGE 86
4-22 Chapter 4, Advanced Diagnostics Program IMPORTANT Because several of these selections destroy all information on the fixed disk drive, you may need to reinitialize the fixed disk drive. For more information on initializing the fixed disk drive, refer to operating system documentation. The following paragraphs describe the Format Menu selections.
PAGE 87
Maintenance and Service Guide NOTE: An Unconditional Format should be performed only if you are sure that tracks marked bad on the fixed disk drive are not actually bad. Good tracks may be marked bad as a result of using a defective fixed disk drive controller or controller cable. You must perform a Surface Analysis after an Unconditional Format to identify any additional bad tracks that may exist on the fixed disk drive.
PAGE 88
4-24 Chapter 4, Advanced Diagnostics Program Fixed Disk Drive Backup (Tape) The Fixed Disk Drive Backup (Tape) test verifies the tape backup, the fixed disk drive controller, the tape host adapter, and associated cables. Depending on the computer configuration, the Fixed Disk Drive Backup Menu may appear.
PAGE 89
Maintenance and Service Guide Fixed Disk Drive Backup The Fixed Disk Drive Backup selection verifies that the system can identify the following on selected tracks of the tape cartridge: drive type; cartridge in place; write protect, beginning of tape (BOT), and end of tape (EOT) sensors; drive motion and seek circuitry; drive indexing circuitry; and drive write and read circuitry. 4-25 Enhanced Color Graphics For a description of this test, see “Video Tests” described previously.

Maintenance and Service Guide 5.4 MEMORY ERROR CODES Memory error codes appear when the system detects a memory fault during the Power-On Self-Test (201 or 203 error codes) or as a result of a diagnostic test (203 error codes). The TEST programs attempt to isolate the memory fault to a specific location, then generate a memory error code that identifies the defective system memory board or system memory module to be replaced. The memory error code points to a specific memory address.

PAGE 205
Maintenance and Service Guide To replace the 387 Coprocessor, follow these steps: CAUTION The most important step when installing the 387 coprocessor in a COMPAQ DESKPRO 386 Personal Computer is orientation of the coprocessor. See Figure 7-38 for the correct orientation. Pay particular attention to the relative positions of the beveled corners that indicate the location of Pin 1 on the 387 coprocessor. 7-47 2.
PAGE 206
7-48 Chapter 7, Removal and Replacement Procedures CAUTION More pressure is needed to press the coprocessor into the socket than is required for installing memory chips. BE SURE the pressure exerted is firm enough to seat the coprocessor and is applied evenly over the surface of the coprocessor. 3. Press the coprocessor into the coprocessor socket. NOTE: If you think the coprocessor is not seated properly, use the coprocessor removal tool to remove the coprocessor, and try again to install it. 4.

Maintenance and Service Guide The COMPAQ Enhanced Color Graphics Board has two banks of configuration switches (SW1 and SW2) as well as two jumpers (P1 and JP3) that must be positioned to allow the board to work properly with your computer system (Figure 8-18). The monitor you use with the COMPAQ Enhanced Color Graphics Board determines the correct setting for one of the jumpers and one bank of configuration switches.

NOTE: A terminating resistor must be installed on a 300-Megabyte Fixed Disk Drive. Refer to Chapter 7, REMOVAL AND REPLACEMENT PROCEDURES, for detailed steps. If two drives are present in the expansion unit, only one drive should have a terminating resistor.

Chapter 9 MASS STORAGE CONFIGURATION 9.1 THEORY OF OPERATION The 300-/600-Megabyte Fixed Disk Drive Expansion Unit can be used with a COMPAQ DESKPRO 386-based Personal Computer with system ROM revision G or later. The expansion unit can be used as a normal external fixed disk drive for maximum storage or in a mirroring or duplexing mode. The three options are described below: □ Maximum storage. This gives you the maximum storage space available in the drives.
PAGE 258
9-2 Chapter 9, Mass Storage Configuration □ Duplexing. The main difference between mirroring and duplexing is that the two drives in the mirrored unit operate off one controller and the two fixed disk drives in the duplexed unit operate off two controllers. An advantage of using dual controllers for duplexing is that the data retrieval speed is increased and the second controller provides additional protection if the system fails.
PAGE 259
Maintenance and Service Guide 9-3 For MS-DOS (with the device driver) to support any two internal fixed disk drives, with one expansion unit, two rules must be followed. □ A maximum of two controllers may be plugged into the system bus. □ Each controller may support only two fixed disk drives. Example: With the use of two expansion units, a total of 1.2 gigabytes of fixed disk storage is available, divided into four 300-Megabyte volumes. This configuration with switch settings is shown in Figure 9-1.
PAGE 260
9-4 Chapter 9, Mass Storage Configuration Mirroring IMPORTANT Novell Netware software must be used when setting up the system for proper operation of the mirroring function. Two possible mirroring configurations are currently supported by COMPAQ Computer Corporation. The first uses two 40-Megabyte internal half-height fixed disk drives as shown in Figure 9-2.
PAGE 261
Maintenance and Service Guide 9-5 Duplexing IMPORTANT Novell Netware software must be used when setting up the system for the duplexing function to work. COMPAQ Computer Corporation also supports one duplexing configuration. Duplexing is supported with two separate controllers plugged separately into the System Bus, and requires the use of two 300-/600-Megabyte expansion units, each equipped with two 300-Megabyte fixed disk drives.
PAGE 262
9-6 Chapter 9, Mass Storage Configuration 9.3 SETTING UP THE EXTERNAL FIXED DISK DRIVE EXPANSION UNIT NOTE: The EXTDISK.SYS device driver needs to be installed in the CONFIG.SYS file only if you are running the expansion unit at the secondary address. If the EXTDISK.SYS device driver is used, then DOS Version 3.31 or later must also be used. After you run SETUP, insert the EXTDISK into drive A and copy the EXTDISK.SYS file to the directory that contains the MS-DOS files. You must then modify the CONFIG.
PAGE 263
Maintenance and Service Guide Use the FDISK utility to partition each fixed disk drive that is to be used with the expansion unit. Each fixed disk drive can have up to four partitions. If the expansion unit is configured at the primary address, that fixed disk drive must contain a primary DOS partition. This primary partition is created with the menu-driven FDISK utility. This fixed disk drive may also contain an extended partition, which can contain logical drives.
PAGE 264
9-8 Chapter 9, Mass Storage Configuration □ SFT II (disk duplexing) goes beyond disk mirroring in both fault tolerance and performance. It helps ensure continuous system operation if either a fixed disk drive or a controller fails. It improves performance by simultaneously servicing two disk write or read requests and by selecting the fixed disk drive that is best able to service a given read request. Duplexed drives typically perform read operations twice as quickly as mirrored drives.
PAGE 265
Maintenance and Service Guide □ NVCPQDSK is for use with mirrored or duplexed disk configurations that require maximum performance. NOTE: Execution of the NetWare UNMIRROR command terminates write duplication on mirrored or duplexed drives. The UNMIRROR command has no effect on which disk drive is in use. NetWare must be reinstalled in order to change from one fixed disk drive to another.
PAGE 266
9-10 Chapter 9, Mass Storage Configuration 3. Install the external fixed disk drive controller. Refer to Chapter 7, REMOVAL AND REPLACEMENT PROCEDURES. 4. Follow the instructions in Chapter 3, SETUP PROGRAM, for running the SETUP program to initialize the CMOS memory to reflect the number of fixed disk drives currently installed. 5. Insert the EXTDISK diskette into drive A and restart the computer. 6. Copy the files with .
PAGE 267
Maintenance and Service Guide 7. If you applied the patch, place the patched files on the working copies of the appropriate NetWare diskettes. Use the NETGEN program to generate and link the NetWare operating system and utilities. 8. Run COMPSURF to perform a surface analysis on the server fixed disk drives.
