Diamond Multimedia Introduces Enhanced Windows 95 Drivers for Supra NetCommander ISDN Modems.

SAN JOSE, Calif.--(BUSINESS WIRE)--Oct. 31, 1996--Diamond Multimedia Systems, Inc. (Nasdaq: DIMD) today announced certain software enhancements for its award-winning Supra NetCommander ISDN modems.

The new driver software, version 3.00, provides support for Microsoft's recent updates to the Windows 95 operating system, including the ISDN Accelerator Pack for Windows 95 (version 1.1) and the Windows 95 OEM Service Release 2 (OSR2). Current Supra NetCommander ISDN customers can obtain the new driver software directly from Diamond's Web site (http://www.diamondmm.com), ISDN BBS, electronic services or through customer service.

By supporting the new ISDN Accelerator Pack, Supra NetCommander ISDN users now have the choice of selecting either Microsoft's Multilink-PPP or Diamond's bandwidth-on-demand Multilink-PPP. "Diamond's bandwidth-on-demand feature is valuable because it enables our customers to save money by paying only for the bandwidth they need," said Paul Corning, ISDN product marketing manager for Diamond Multimedia. "The Supra NetCommander ISDN can initiate a call using a single channel, then automatically add or drop a second channel depending on the amount of data demanded by the user."

The new ISDN Accelerator Pack 1.1 from Microsoft supports Multilink-PPP which allows multiple data links to be combined. For example, two 64,000 bps ISDN "B" channels can be combined for a 128,000 bps connection. Additionally, Microsoft's new ISDN Accelerator Pack enables the Supra NetCommander ISDN to answer incoming ISDN data calls, allowing Windows 95 PCs to function as ISDN servers. Microsoft's Windows 95 OSR2 will be included in the shipments of new PCs from a variety of system manufacturers.

With Diamond's new driver software, users can install the Supra NetCommander ISDN over any combination of Microsoft's Windows 95 software (original release or OSR2) and Microsoft's ISDN Accelerator Pack (versions 1.0 or 1.1). To download the Supra NetCommander ISDN version 3.00 drivers including Microsoft's new ISDN Accelerator Pack for Windows 95, check the Diamond Multimedia Web site at http://www.diamondmm.com.
