PARALLEL PORT CONFIGURATION Parallel Port JP18 JP19 LPT1 pins 1 & 2 closed pins 2 & 3 closed LPT2 pins 1 & 2 closed pins 1 & 2 closed LPT3 pins 2 & 3 closed pins 1 & 2 closed Disabled pins 2 & 3 closed pins 2 & 3 closed WATCHDOG TIMER CONFIGURATION Timer Mode JP21A JP21B JP21C Always enabled closed open open Software selectable open closed open 1 Always disabled open open closed Note 1 :To enable and refresh the timer, read I/O port 443h. To disable the timer, read I/O port 043h. WATCHDOG TIMER INTERVAL CONFIGURATION Timer Interval JP24A JP24B JP24C Short (1.5 closed open open seconds) Medium (15 open closed open seconds) Long (150 seconds) open open closed Note: When the Watchdog Timer is enabled, it will reboot the system at the above selected interval unless I/O port 443h is read before the timer expires. The timer is only accurate ± 30% - so if the timer is set to reboot the system every 15 seconds, make sure I/O port 443h is read within approximately every 10 seconds. ROM DISK CONFIGURATION EPROM Size Drive JP30A JP30B JP30C Emulation 1M (360KB A: pins 1 & 2 pins 1 & 2 pins 1 & 2 floppy) closed closed closed 1M (360KB B: pins 1 & 2 pins 1 & 2 pins 2 & 3 floppy) closed closed closed 4M (1.44MB A: pins 2 & 3 pins 2 & 3 pins 1 & 2 floppy) closed closed closed 4M (1.44MB B: pins 2 & 3 pins 2 & 3 pins 2 & 3 floppy) closed closed closed Note: The utility "COOKROM.EXE" will convert either a 360KB or a 1.44MB floppy disk into three files: ROM1.BIN, ROM2.BIN and ROM3.BIN (If the disk doesn't contain much data, then there may be only one or two files created). These files then may be placed (using an EPROM Burner that supports an Intel D27C0040 512K x 8 EPROM) onto up to three EPROMs. The EPROM that now contains the file ROM1.BIN should be placed in socket U19. The EPROM that now contains the file ROM2.BIN should be placed in socket U29. The EPROM that now contains the file ROM3.BIN should be placed in socket U34.
