The CONFIG.SYS File

The installation program adds the following statements to the CONFIG.SYS file:
DEVICE=C:\WINDOWS\HIMEM.SYS

System Resource
Settings
This section explains the following software SB emulation resources—not hardware resources—
of your card:
❑
Input/Output (I/O) Addresses
❑
Interrupt Request (IRQ) Line
❑
Direct Memory Access (DMA) Channel
If your card encounters a conflict with a peripheral device, you may need to change its resource
settings. For details, see “Resolving I/O Conflicts” on page C-7.
When any resource setting is changed, make sure that the environment variables (see
“Environment Variables” on page B-5) reflect the changes as well. You can view your system
environment by typing
SET
at the DOS prompt.
Input/Output (I/O)
Addresses
I/O addresses are communication areas used by your computer’s central processor to distinguish
among various peripheral devices connected to your system when sending or receiving data.
In the following tables, the
preferred values are in bold.
