At first, the 9 2.2 Your PSC-586 Single Board Computer contains sensitive electronic In this section, we describe the precautions you should take while unpacking, as well as during installation. It is very important that the The system board should be done on a grounded anti-static mat. The operator should be wearing an anti-static wristband, grounded at the same point as the anti-static mat. Inspect the cardboard carton for obvious damage. Shipping and handling may cause damage to your board. Be sure there are no shipping and handing damages on the board before processing. After opening the cardboard carton, exact the system board and place it only on a grounded anti-static surface component side up. Again inspect the board for damage. Press down on all the socketed IC's to make sure that they are properly seated. Do this only with the board place on a firm flat surface. You are now ready to install your PSC-586 Single Board Computer. 10 DAMAGED. Note : DO NOT APPLY POWER TO THE BOARD IF IT HAS BEEN successfully install the board. instructions be followed correctly, to avoid static damage, and to components that can be easily damaged by static electricity. Unpacking You can change the PSC-586's configuration by setting jumper switches on the board. The board's jumpers are preset at the factory. Under normal circumstances, you should not need to change the jumper settings. A jumper switch is (sometimes referred to as shorted with the plastic cap inserted over two pins of the jumper). A jumper is with the plastic cap inserted over one or no pin(s) of the jumper. this chapter.

PCI IDE IRQ Map to : PCI-Auto - BIOS will scan all PCI add-on cars and determine the location of the PCI IDE devices. PCI-Slot1 - Assign IRQ14 for primary IDE INT# and IRQ15 for secondary IDE INT# for the PCI-slot1 35 Slot 1-4 Using INT# : PCI-Slot2 - Assign IRQ14 for primary IDE INT# and IRQ15 for secondary IDE INT# for the PCI-slot2 PCI-Slot3 - Assign IRQ14 for primary IDE INT# and IRQ15 for secondary IDE INT# for the PCI-slot3 PCI-Slot4 - Assign IRQ14 for primary IDE INT# and IRQ15 for secondary IDE INT# for the PCI-slot4 ISA - The setting is for some PCI IDE cards which directly connect the IRQ14 and IRQ15 to ISA slot thru a cord. This cord is called the Legacy Header. The Watch-Dog Timer is provided to ensure that standalone systems can always recover from catastrophic conditions that caused the CPU to crash. This condition may have occurred by external EMI or a software bug. When the CPU stops working correctly, hardware on the board will either perform a hardware reset (cold boot) or a non- maskable interrupt (NMI) to bring the system back to a known state. The Watch-Dog Timer is controlled by two I/O ports. 443Enable the refresh the Watch-Dog Timer. (hex) 043Disable the Watch-Dog Timer. (hex) To enable the Watch-Dog Timer, a read from I/O port 443H must be performed. This will enable and activate the countdown timer which will eventually time out and either reset the CPU or cause an NMI depending on the setting of JP18. To ensure that this reset condition does not occur, the Watch-Dog Timer must be periodically refreshed 36 Read Read Appendix A. Watch-Dog Timer by reading the same I/O port 433H. This must be done within the time A tolerance of at least 30% must be maintained to avoid unknown routines within the operating system (DOS), such as disk I/O that can be very time consuming. Therefore if the time out period has been set to 5 seconds, the I/O port 443H must be read within 3.5 seconds. Note: when exiting a program it is necessary to disable the Watch-Dog Timer, otherwise the system will reset. 37 out period that is selected by jumper group JP19. 10 11 20 30 40 50 60 70 80 90 1000 1070 2000 2070 5000 5010 5020 6000 6010 6020 38 RETURN X = INP( &H43) REM RESET WDT REM SUBROUTINE TO DISABLE THE WDT RETURN X = INP( &H443) REM ENABLE AND REFRESH TIMER REM SUBROUTINE TO ENABLE AND RESET WDT RETURN 3 SECONDS TO COMPLETE REM SUBROUTINE #2 RETURN 2 SECONDS TO COMPLETE REM SUBROUTINE #1 GOTO 30 GOSUB 5000 REM ENABLE AND REFRESH THE WDT GOSUB 3000 REM TASK 3, 5 SECS GOSUB 6000 REM DISABLE THE WDT GOSUB 2000 REM TASK 2, 3 SECS GOSUB 5000 REFRESH THE WDT GOSUB 1000 REM TASK 1, 2 SECS GOSUB 5000 REM ENABLE AND REFRESH THE WDT REM WATCH-DOG TIMER == WDT REM EXAMPLE PROGRAM
