These files contain the instructions for loading the Turbo/TP software drivers, release notes that you could find helpful for your installation, and how to configure your system. Installation 1-11 2 ------------------------------------------------------------ Configuration 2.1 Introduction The Turbo/TP board switch pack has 12 switches that enable the board to operate in a configuration without interference from the other boards in your computer. This chapter describes how to change the settings on the switch pack. If you have many options in your system, you may have to change the interrupt request (IRQ) line, the I/O address setting, or the memory address setting on the Turbo/TP board to create a compatible operating set. 2.2 Default Settings The Turbo/TP board is shipped with the switches preselected (default settings) to work in most installations. Table 2-1 lists the default settings. Configuration 2-1 Table 2-1 Switch Pack Default Settings ------------------------------------------------------------ Switch Position Function Default ------------------------------------------------------------ SW1 SW2 ON OFF Sets the memory address range. Sets the memory address range to D0000 - DFFFF (hex). ------------------------------------------------------------ SW3 SW4 ON ON Selects the buffer memory size. Enables 64 KB memory size. ------------------------------------------------------------ SW5 ON Sets the I/O address. I/O starting address is set to 300 (hex). ------------------------------------------------------------ SW6 ON Enables or disables remote boot feature. 1 Remote boot disabled. ------------------------------------------------------------ SW7 OFF Sets the timeout period for the remote boot attempt. 1 Sets a 30 second timeout period. ------------------------------------------------------------ SW8 ON Enables IRQ5 IRQ5 enabled ------------------------------------------------------------ SW9 SW10 SW11 SW12 OFF OFF OFF OFF Enables IRQ9 Enables IRQ10 Enables IRQ11 Enables IRQ12 IRQ9 disabled IRQ10 disabled IRQ11 disabled IRQ12 disabled ------------------------------------------------------------ 1 This feature requires that a remote boot ROM chip be installed. See Appendix B for more information. ------------------------------------------------------------ The default settings are illustrated in Figure 2-1. 2-2 Configuration Figure 2-1 Switch Pack Default Settings Configuration 2-3 2.3 Check the Other Boards You can set only one board in the computer to use a specific interrupt request line, I/O address, or memory address. If you do not know the settings for the other boards: · Ask your system administrator for a list of the settings. · Check the board documentation for the possible settings. · Inspect the boards to determine the actual settings. If you find that a conflict exists, you can change the appropriate setting on the Turbo/TP board, as described in following sections. The switches being described are highlighted in the illustrations. 2-4 Configuration 2.4 Memory Addressing Range and Size Selection (SW1 - SW4) Switches SW1 and SW2 select the memory addressing range, and SW3 and SW4 select the size of the system memory space the Turbo /TP board uses. Table 2-2 lists six possible memory addressing ranges and the switch settings that select them. Only one board can be set to use a given memory addressing range. Check the documentation supplied with your personal computer and other boards to determine memory address requirements. If the other boards in your computer use memory addressing ranges that conflict with one of these ranges, select a range that is unused. Table 2-2 Switch Settings and Memory Addressing Ranges ------------------------------------------------------------ Buffer Size SW1 SW2 SW3 SW4 Memory Addressing Range ------------------------------------------------------------ 64 KB ON ON ON ON C0000--CFFFF ON OFF ON ON D0000--DFFFF (default setting) OFF ON ON ON E0000--EFFFF 1 ------------------------------------------------------------ 32 KB ON ON OFF OFF C8000--CFFFF ON OFF OFF OFF D8000--DFFFF OFF ON OFF OFF E8000--EFFFF 1 ------------------------------------------------------------ 1 Some PCs do not support the E0000 - EFFFF or E8000 - EFFFF address ranges. Check your personal computer manual for this information. ------------------------------------------------------------ ------------------------------------------------------------ Note ------------------------------------------------------------ Setting both SW1 and SW2 to the OFF position is an illegal configuration and may prevent the computer from working correctly. ------------------------------------------------------------ Configuration 2-5 The Turbo/TP board works best when the entire 64 KB of network buffer memory is enabled for its operation. Some boards and system configurations do not permit the allocation of this amount of memory. Network performance is slower when you select 32 KB, but you can use the Turbo/TP board in configurations where address space is at a premium. Example: Figure 2-2 shows the settings for SW1 through SW4 that select a buffer size of 32 KB in the C8000 - CFFFF (hex) system memory addressing range. 2-6 Configuration Figure 2-2 Setting Memory Range C8000-CFFFF for 32 KB Configuration 2-7 2.5 I/O Address Selection (SW5) The Turbo/TP board uses one of two I/O address ranges (primary or secondary) to communicate with the CPU. Only one board in the computer can be set to use a given I/O address range. · Switch SW5 set to ON selects the primary I/O address range (300 - 30F; default setting). · Switch SW5 set to OFF selects the secondary I/O address range (200 - 20F) (Figure 2-3). 2-8 Configuration Figure 2-3 Switch Selecting I/O Address 200 - 20F (hex) Configuration 2-9 2.6 Remote Boot Selection (SW6) Switch SW6 determines whether the remote boot feature is enabled or disabled. 1 · Switch SW6 set to ON disables remote boot (default setting). · Switch SW6 set to OFF enables remote boot (Figure 2-4). ------------------------------------------------------------ 1 This feature requires that a remote boot ROM chip be installed. See Appendix B for more information. 2-10 Configuration Figure 2-4 Switch Enabling Remote Boot Configuration 2-11 2.7 Remote Boot Period Selection (SW7) Switch SW7 controls the time period for trying to enable a remote boot operation. · Switch SW7 set to OFF sets the remote boot timeout to 30 seconds (default setting). · Switch SW7 set to ON sets the remote boot timeout to 150 seconds. Figure 2-5 Switch Selecting 150 Seconds for Remote Boot 2-12 Configuration 2.8 Interrupt Request Line Selection (SW8 - SW12) You can use switches SW8 through SW12 to select an interrupt request line (IRQ). The Turbo/TP board uses one IRQ line for the network interface (NI). Table 2-3 lists switches and the interrupt request lines enabled. Table 2-3 Interrupt Request Line Switch Selection ------------------------------------------------------------ Switch Interrupt Request Line ------------------------------------------------------------ SW8 IRQ5 (default setting) SW9 IRQ9 SW10 IRQ10 SW11 IRQ11 SW12 IRQ15 ------------------------------------------------------------ Only one switch should be set to the ON position. By default, SW8 is set to the ON position, selecting IRQ5. Example: To select IRQ10 as the interrupt request line, set switch SW10 to the ON position and set switches SW8, SW9, SW11, and SW12 to the OFF position (Figure 2-6). Configuration 2-13 Figure 2-6 Switch SW10 Selecting IRQ10 2-14 Configuration 3 ------------------------------------------------------------ Problem Solving This chapter describes problems you may encounter with the Turbo/TP board and suggests possible causes and solutions. 3.1 Fault Isolation By Symptom Table 3-1 lists problems that you might encounter, the possible cause, and the recommended corrective action.

You can install the board in any IBM/AT or a computer that has an IBM/AT compatible bus. You can connect the Turbo/TP board to either a 10BaseT Twisted-Pair network or a ThickWire Ethernet network. You cannot, however, connect the board to both kinds of networks at the same time. A.2 Physical Description The Turbo/TP board is a half-length IBM/AT form-factor board that uses the full 16-bit bus connector. The board measures 17.2 cm x 10.8 cm (6.75 in x 4.25 in). A.2.1 Functional Components The major functional components of the Turbo/TP board are as follows: · Ethernet network protocol controller (LANCE) · Unshielded twisted-pair (RJ45 connector) network interface · Standard Ethernet ThickWire (DB-15S connector) network interface General Information A-1 · Diagnostics and remote-boot ROM - 16 KB (optional) · Network buffer RAM - 64 KB · Ethernet hardware address ROM A.2.2 LED There are two light emitting diodes (LEDs) on the mounting bracket that indicate the operating status of the Turbo/TP board. The amber LED comes on during power-up testing and stays on if the test discovers a fault. When the green LED is on it indicates normal network activity. Chapter 3 contains additional information on the LEDs. A.2.3 Environmental Requirements The environmental (temperature and humidity) requirements for the Turbo/TP board are the same as for your IBM/AT personal computer. A.3 System Specifications The Turbo/TP board operates correctly at an I/O channel bus speed of 6 MHz or 8 MHz. Table A-1 lists the system specifications of the board.
