If you are developing KM488-ROM application programs in C, TURBO PASCAL or
QuickBASIC, the installation process is now complete. However, if you are developing
programs in BASICA and have changed the factory default settings, you must to run the
EEI’ROM configuration program CONFIG.
2.6
CONFIGURATION OF THE EEPROM
When KM488-ROM application programs use BASICA, the programs read interface
functions directly from the on-board EEPROM. Thus, the EEPROM must be properly
configured, which may be accomplished using the CONFIG program. This program allows
you to change such parameters of the EEPROM configuration as I/O Base Address, l/O
Timeout, DMA Timeout, and Transmit/Receive Terminators.
Before changing the EEPROM configuration, you may want to read the descriptions of the
DMA, RCV, and XMIT routines in Chapter 3. Also make sure that the ROM Base Address
switch has the ROM Write function enabled. (See Section 2.4.)
Invoking The CONFIG Program
Invoke the CONFIG program as follows:
1. Install the Distribution Software (see Section 2.3) and the KM488-ROM board (see Section
2.5).
2. Switch to the appropriate directory. At the DOS prompt, type CONFIG
The PC monitor will show a screen labelled
K&-488-ROM CONFIGURATION. The
settings
will reflect any changes which were made by running the INSTALL program.
The following PC function keys are now active:
[E-II
[ml
[F31
I Shift II F3 I
[AltI[F31
[F81
HELP Invoke Help at any time by pressing [ Fl ]
SHOW NEXT. In multiple board systems, pressing [ Fl I shows the
configuration of the next KM488-ROM.
LOAD . Pressing this key loads the file KM488ROM.BlN to the EEPROM.
This function is useful when you want to load the factory defaults back
into the KM488-ROM’s EEPROM.
LOAD NEW MEMORY. Pressing this key combination allows you to
load the contents of the KM488-ROM’S EEPROM to a new segment of
DOS memory. The value you enter here must agree with the address
selected by the ROM Base Address Switch. If you have trouble identifying
an unoccupied space, run the MEMMAP program (see Section 2.4).
EDIT I/O ADDRESS. This key combination permits you to edit the I/O
Address field only. This
is
the address for access to the KM488-ROM. It
is important that you select an l/O Base Address on an S-byte boundary
that
does not conflict with other devices in your computer. The I/O Base
Address must fall within the range 200h to 3F8h.
EDIT. This key allows editing of the configuration parameters (see the
next section for parameter descriptions). When editing is complete, press
1 MO 1. When the prompt Save changes to KM-488-ROM memory? Y/N
appears, enter the appropriate response.
