MOPS/386A User’s Guide 65 BIOS Operation
21.9.3.
Silicon Disk BIOS extension
The system BIOS setup of the MOPS/386A allows you to enable the onboard silicon disk as a
bootable Flash disk. When the Interrupt 13h drive mapping is enabled, the Silicon Disk
BIOS extension loads during boot up. The Flash Disk is a BIOS INT 13h compatible
implementation of a solid-state disk. It is a DOS-compatible disk and cannot be used under
protected mode or real-time operating systems.
The BIOS extension is loaded into the first free memory area between C0000hex and
D8000hex, a 32K block of memory is shadowed. This feature also needs the memory area
E0000h to EFFFFh to access the flashes. Also, you can refer to the Silicon Disk chapter of
this user’s guide for more information.
21.9.4.
LAN RPL ROM
If the onboard LAN RPL ROM is enabled in the system BIOS setup, a special optional ROM for
the Ethernet controller loads into memory during boot up. This optional ROM allows you to
boot the MOPS/386A over an Ethernet connection. A server with Etherboot support is
required on the other side of the Ethernet connection. The setup and configuration of the
server, including Etherboot support, is not the responsibility of Kontron.
The RPL ROM extension is loaded into the first free memory area between C0000hex and
D8000hex and a 32K block of memory is shadowed.
21.9.5.
DOT-Matrix LCD BIOS extension
If the DOT-matrix LCD interface is set up by using software tool ALCDINIT.EXE, the BIOS
extension that supports this feature will load during boot up. Refer to the LCD DOT-matrix
Interface chapter for more details.
The BIOS extension for the DOT-matrix LCD loads into the first free memory area between
C0000hex and D8000hex; a 32K block of memory is shadowed. However, if the system
memory cannot find free memory space because all the memory is already used for add-on
peripherals, the BIOS extension will not load.
21.9.6.
Matrix Keyboard BIOS extension
You can enable the Matrix keyboard feature from the system BIOS setup. Refer to the Matrix
Keyboard Interface chapter for more details.
This feature enables results in a load of the Matrix Keyboard BIOS extension into the first
free memory area between C0000hex and D8000hex; a 32K block of memory is shadowed.
