### CONFIG Command

The CONFIG command specifies updates to the CONFIG.SYS file, functioning similarly to the DDINSTAL CONFIG command. Like its DDINSTAL counterpart, the DSPINSTL CONFIG command line is followed by a set of CONFIG.SYS statements that are to be added to the configuration file. However, the DSPINSTL CONFIG command attempts to replace corresponding CONFIG.SYS statements instead of appending them to the file.

The format of the CONFIG command line is :CONFIG.

The following examples illustrate DSP file command lines that can follow the CONFIG command line:

        :CONFIG  :MODE=PRIMARY
        SET VIDEO_DEVICES=BIO_VGA
        SET VIO_VGA=DEVICE(BVHVGA)

        :CONFIG :MODE=PRIMARY :MODE=DOS
        DEVICE=%BOOTDRIVE%:\OS2\MDOS\VVGA.SYS
