Generic Win-OS/2 audio driver. Works under DOS for Win-OS/2 sessions. GWDTA.SYS is the Ring 0 DTA component driver.

DEVICE=GWDTA.SYS <parameters>

Parameters

The following parameters are accepted by the DTA support driver GWDTA.SYS on the load line in the CONFIG.SYS.

/Q: Load quietly
/B:N: Range: 2>n>16
Set default requestor buffer number
/S:M: Range: 1024>m>16384
Set default requestor buffer size
/P:<pddname>: Range : PDDNAME<8chrs
Add an audio PDD to the DTA that is not specified in MMPM/2. Up to five different /P:<pddname> may be specified, and they will appear before the MMPM/2 devices in the order specified. Duplicates will be ignored but their presence will be flagged to the user. If the PDD does not exist the name will be retained but it will be marked invalid.

Note that VGENAUD.SYS uses the first valid PDD in the list harvested by GWDTA, unless a different name is specified on the VDD command line (see VDD: VGENAUD.SYS). For most uses where it is desired to use the primary MMOS/2 soundcard for WinOS/2, this option can be ignored.
/N: Do not scan MMPM/2 for devices - only use those specified on the command line. This option is not normally required.
