The Advanced Menu contains settings for integrated peripherals, memory shadow,
watchdog timer, large disk access mode, and setting the Flash and VME ROMdisk
BIOS extension base addresses.
Integrated Peripherals Sub-Menu
Use this option to select the Integrated peripherals sub-menu, in order to configure the
COM and LPT ports. This does not configure Ethernet, video, or Flash memory. For
more information, turn to the section concerning the Integrated Peripherals Sub-Menu.
Memory Shadow Sub-Menu
The term ‘‘Memory Shadow’’ refers to the technique of copying information from
ROM into RAM and accessing it in this alternate memory location. For more
information, turn to the section concerning the Memory Shadow Sub-Menu.
Halt on watchdog timer:
This sets the action for the BIOS to take following a hardware reset condition caused
by a timeout of the watchdog timer on the EPC-8. When such a timeout occurs, first
the system generates a VMEbus SYSRESET. The EPC-8 will then either halt,
displaying an error message, or will simply reboot, depending on the entry here.
Large Disk Access Mode:
If using a drive larger than 512 Mbytes, set this to DOS if you are running DOS, or set
this to Other if using a different operating system.
Built-in BIOS Extension Configuration
BIOS Extension Base Address
Flash ROMdisk:
Use this option to enable Flash memory on the EPC-8. This must be selected for the
Flash memory to appear as a drive. The base address you select defines where the
Flash ROMdisk BIOS extension is installed.
