Interface Boards and Mass-Storage
SCSI/LAN Combination Board
Optional BootROM Socket
It is possible to add a flash device on the network card socket with a specific LAN
BootROM code. This new BootROM code will be seen and mapped automatically by the
system BIOS instead of the embedded version (system BIOS).
NOTE If you are looking for a specific or a new version of the BootROM, refer to the
LANWORKS web site at: http://www.lanworks.com.
Flash / ROM Devices
The 10BT/100TX card provides a PLCC 32-pin socket, and any size of flash device can be
used up to 256 KB.
Installing Two LAN Remote Power On Cards
From a network standpoint, it is possible to install two LAN RPO cards, and both cards
will be functional (for example, from the operating system, it will be possible to have two
LAN cards up and running at the same time).
However, there are restrictions due to the remote manageability boot features
implementation. To support these features, an internal cable is required between the LAN
card and the system board. However, only one card can be attached to this cable, so that
remote manageability features are supported on one card only.
The problem is that with the current BIOS and hardware implementation, it is not
possible to identify which LAN card the cable is attached to, and this may result in having
none of the remote capabilities working properly.
Even though it is possible to install two LAN Remote Power On cards in the computer, only
one card is seen by the BIOS setup. In conclusion, when installing two LAN cards, always
remember that it is very difficult implement the RPO functionality on a LAN card.
NOTE Administrative tools (for example, TopTool Openview) are not capable of
identifying which network board WOL is connected to.
