Network Boot - Advantech PCM-4862 Manual

10BASE-T connects to the PCM-4862 via an adapter cable to a 10-
pin polarized header (CN10). For 10BASE-T RJ-45 operation, an
adapter cable converting CN10 into a standard RJ-45 jack is
required.
The Network Boot feature can be utilized by incorporating the Boot
ROM image files for the appropriate network operating system. The
Boot ROM BIOS files are available from your supplier. They can be
programmed into the BIOS, similar to the VGA BIOS file, using the
AWDFLASH.EXE program detailed in Chapter 3.
An on-board watchdog timer reduces the chance of disruptions
which EMP (electro-magnetic pulse) interference can cause. This is
an invaluable protective device for standalone or unmanned
applications. Setup involves two jumpers and running the control
software (refer to Appendix A).
You can enable or disable the watchdog timer by reading the card's
I/O ports with your program. Read address 443 hex to enable and
refresh the watchdog or address 043 to disable the watchdog. For
information on programming the watchdog timer see Appendix A.
When the watchdog timer activates (CPU processing has come to a
halt), it can reset the system or generate an interrupt on IRQ15.
This can be set via two 2-pin jumpers (J23, J24) as shown below:
