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.

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.
