PCC-10 User's Guide 2-9
10. “<<INSTALLATION COMPLETE>>” will be shown followed by several options
for modifying the default settings of the PCC-10 DOS Device Driver. The
location of the README.TXT file C:\LONWORKS\IMAGES\PCC10\README.TXT
will also be shown. Press any key other than ESC to continue.
11. If the installation program did not automatically update the CONFIG.SYS file,
it should be done manually at this time.
12. Installation is complete. Remove the PCC-10 installation diskette and restart
the computer. Note that Windows will not recognize the PCC-10 card until the
computer is restarted.
Configuring the PC for Maximum Performance
Under DOS
This section describes setting up the PC to obtain the maximum performance from
the DOS driver. The performance of the PCC-10 DOS Device Driver
software can
be greatly enhanced by correctly configuring the PC’s conventional memory.
Many of the changes described in this section require changes to your CONFIG.SYS
or AUTOEXEC.BAT files. Be sure to reboot the PC after making these changes so
that the new settings can take effect.
Conventional Memory
The PCC-10 DOS Device Driver requires conventional memory equal to the actual
size of the device driver plus 260 bytes per input or output buffer set in the
LDVPCC10.INI file for all device handles (LON1, LON2, etc.):
Required Memory = Driver Size + (260 * (Total Input Buffers + Total Output
Buffers))
The amount of conventional memory available is determined by the total
conventional memory of the PC, the version of DOS, the DOS configuration, and
memory-resident drivers, and programs.
Conventional memory may be increased by using a memory manager such as
Microsoft MemMaker or the Quarterdeck Expanded Memory Manager (QEMM-
386), or by loading DOS into High or Extended Memory using EMM386.SYS with
DOS 6.2 or later. Extended memory is the memory beyond the first 1 MByte of
address space in the PC. Consult the DOS documentation provided with the
computer for details.
LDVPCC10.INI
File Description
The LDVPCC10.INI file is an ASCII text file which contains sections defining up to
four (4) PCC-10 Card devices. Each section name defines the device name,
typically LONn, but can be any eight (8) -character device name. A section name is
a word enclosed in brackets, i.e., [LON1]. A new word within brackets defines a
new section.
