Binary Configuration Program BCP/BCPX
The Binary Configuration Program „
BCP
“ is an interactive DOS program that allows to read,
modify and write back the binary BIOS image file on the host PC. The modified BIOS image
must be downloaded to the NETIPC board using the Boot Loader program. Currently two
versions of this program are available:
•
BCP.EXE: binary configuration program for Embedded BIOS 4.x.
•
BCPX.EXE:
binary configuration program for Embedded BIOS 5.x.
BCP patches the binary BIOS file BIOS.BIN while BCPX patches the binary BIOS file
BIOSF.BIN.
WARNING
: be very careful when changing BIOS parameters. Make sure that you understand
each parameter you change and do not change in case of doubt. A wrongly configured BIOS
may result in malfunction or inoperability of the NETIPC or an Input-/Output-module !

Modifiable Options
The following options may be modified using BCP(X):
Menu Target Board
Allows setting of the target board type. This has effects on the setting of some board type
dependent options, e.g. maximum memory size.
Note:
Always set the Target Board before modifying other parameters.
Menu COM ports
For each of the four COM ports the I/O base address, the BIOS int14 initialization byte,
automatic RTS assertion and clock scaling in BIOS int14 initialization routine may be defined.
The init byte is set to 9600 baud, no parity, 8 data bits, one stop bit by default. Automatic RTS
and DTR assertion is enabled by default and may be disabled in case the COM port is used with
half duplex RS485 driver circuit where the transmitter enable is controlled by the RTS line.
Clock scaling is used to scale the baud rate divisor in case of a non standard clock frequency
attached to the COM ports UART device. It is set to 0 by default for the standard 1.8432 MHz
clock. Select 1 for 3.6864 MHz and 2 for 7.3728 MHz clocks.
Note:
When defining the COM1..4 I/O ports, no gap (e.g. COM3 = I/O port 0) must be
configured.
Menu LPT ports
Allows setting of the I/O base address for each of the three LPT ports supported by the BIOS.
