BLASTER Environment Variable
Overview
Environment variables are used to pass hardware configuration information to the software in
your system. For MS-DOS, your audio card includes the following:
CTSYN Environment Variable
●
BLASTER Environment Variable
●
CTSYN Environment Variable
The CTSYN environment variable points to the location of the CTSYN.INI file, which usually
resides in the Windows directory. The syntax for this variable is as follows:
CTSYN=path
where path is the location of the CTSYN.INI file.
BLASTER Environment Variable
The BLASTER environment variable specifies the base I/O address, IRQ line, and DMA
channels of the SB interface. Its syntax is:
BLASTER=A220 I5 D1 H5 P330 T6
The parameters in the command are as follows.
This
Parameter
Specifies
A
xxx
SB interface’s base I/O address.
I
x
IRQ line used by the audio interface.
D
x
First DMA channel used by the audio interface.
H
x
Second DMA channel used by the audio interface.
P
xxx
MPU-401 UART interface’s base I/O address.
