Customizing The Board 5-5
5.7 Configuring the TEK-AT4L
PLUS
Configuring your board is purely a matter of the application at hand. As an example, a
2MB system can be defined as 640KB base + 384KB 1 MB extended memory,
or, 640KB base + 384KB 512KB ex 512KB EMS and so on. The user
is free to adapt the configuration to his particular needs.
5.8 SW1 - Configuration Jumpers
The TEK-AT4L
PLUS
supports an onboard BIOS extension which controls certain
functions of the BIOS related to industrial applications. The extended BIOS reads the
settings of the SW1 jumpers and acts accordingly.
Upon system start-up, the BIOS automatically determines how much ROM/RAM disk
memory is available to the system, and what equipment is connected to the system.
