This section describes the software environment for a VRC 6940 terminal. A VRC 6940 has
four drives as described in Table B-1:
Table B-1. VRC 6940 Drives
Drive Size Type Contents
A:\ 256 Kb Flash,
EPROM
This drive contains:
• BIOS, including the Command Mode menus and
commands and Self-Test software
• Essential system drivers
• DOS
B:\ 256 Kb Flash,
EEPROM
This drive is the main space for user applications. For
the first installation, it contains the LWP hex image.
The first time you boot a terminal, LWP copies utilities
and applications onto the E:\ drive. When you load
user applications onto the terminal, they overwrite
LWP, but the utilities and applications stay on the E:\
drive.
See Chapter 4 for information on loading applications
into this space.
D:\ 160 Kb RAM This drive contains the net.cfg file and user space.
Commands in the b:\autoexec.bat file can write
files to this disk.
The default size is 160 Kb, but this size can be changed
by b:\init.exe. For information on setting the D
drive size, see Chapter 5 of the Series 3000 Application
Programmer’s Guide (p/n 70-16308-XX).
