- Microsoft Delivers Second Phase of Portable Computing Initiative
-
- Microsoft Flash File System Facilitates Application Development of MS-DOS,
- Windows Software
-
- REDMOND, Wash. -- April 22, 1992 -- As part of its ongoing commitment to
- aid PC manufacturers and software developers in meeting the needs of the
- portable computing and embedded system markets, Microsoft Corporation
- today announced the Microsoft Flash File System. The file system is the
- first to allow flash memory to function as an ordinary disk in a PC,
- making it easier for users to run their favorite applications for MS-DOS
- and Windows operating systems on a wide range of PC platforms, including
- pen-centric, palmtop and desktop environments. The Microsoft Flash File
- System also makes it easy to develop custom MS-DOS and Windows
- applications for embedded systems and consumer electronic devices by
- allowing developers a wide range of existing MS-DOS and Windows
- development tools. Flash memory is a type of non-volatile memory that can
- read data as quickly as a RAM disk, as well as write and store data like a
- hard disk.
-
- Today Microsoft also released the specifications for the Microsoft Flash
- File System media control structures, which determine how data is stored
- on flash memory cards using the Microsoft Flash File System. The move
- allows the industry to focus on a single format for reading and writing
- data using flash memory. This allows users to work with flash memory cards
- as easily and interchangeably as they now use floppy disks, because they
- can utilize memory cards on any PC that supports the Microsoft Flash File
- System. A single format also allows disk utilities vendors to create new
- tools that provide solutions targeted at the needs of memory card users.
-
- The Microsoft Flash File System, now in beta testing, is scheduled to be
- released this summer. The file system supports PCMCIA-compliant flash
- memory. The PCMCIA, or Personal Computer Memory Card International
- Association, is a non-profit trade association established to develop and
- maintain a worldwide standard for PC Cards. At the same time, the file
- system supports the use of flash memory in dedicated applications -- such
- as electronic point of sale systems, which are not traditionally
- PCMCIA-compliant.
-
- Microsoft made the announcements during Intel Corporation's unveiling of
- its Series 2 flash memory cards today to underscore the importance of the
- companies' dual contributions to portable computing, according to Brad
- Silverberg, vice president of personal systems at Microsoft. Microsoft's
- Flash File System supports Intel's Series 2 cards as well as flash memory
- cards from other manufacturers. In November, Microsoft and Intel jointly
- released their Advanced Power Management (APM) specification for extended
- battery life in portable computers.
-
- "Microsoft is working to bridge the gap between the desktop, the palmtop
- and beyond," said Silverberg. "Our Portable Computing Initiative
- demonstrates our continuing commitment to facilitate portable computing
- for both vendors and users. With today's announcements, we're giving
- developers and users a familiar environment in which to develop and use
- popular applications for MS-DOS and Windows on new, mobile platforms.
-
- "Also, we're enabling people to use their flash memory cards with any
- portable PC that supports the formats -- even those running different
- operating systems," he added. "Together with the industry's move toward
- smaller, lighter computers, these are key steps in achieving the portable
- computing revolution."
-
- Microsoft introduced its Portable Computing Initiative in January of 1992.
- The Initiative covers the full range of the portable market, from
- established laptops and notebook-sized computers to the newer tablet or
- clipboard-type machines, palmtop devices and embedded mobile systems. In
- all, this market is expected to increase from about six million units this
- year to nearly 30 million units in 1995, according to Dataquest, an
- international market research firm.
-
- The first phase of the Portable Computing Initiative included Microsoft' s
- release of APM, MS-DOS 5 ROM version, a fast data transfer utility called
- Interlnk and support for solid-state memory. Microsoft also announced
- plans to make a ROM-executable version of its Microsoft Windows operating
- system version 3.1 available later this year.
-
- Microsoft Flash File System Provides Easy Access to MS-DOS and Windows
- Applications
-
- The Microsoft Flash File System keeps the management of flash memory
- devices transparent to the user, to whom flash cards will appear as
- ordinary disks. This enables users to run their favorite applications for
- MS-DOS or Windows on a diskless system with flash memory as the primary
- storage medium. It also provides an easy way to upgrade applications on
- diskless systems.
-
- The Microsoft Flash File System was designed using a linked-list
- architecture to help ensure that data can be moved easily throughout the
- media. This also enables the file system to maximize its use of all
- available space in flash memory for storing data and applications.
-
- The Microsoft Flash File System consists of two device drivers that users
- can easily load in their CONFIG.SYS files. A high-level driver interfaces
- with MS-DOS to process commands from the operating system or application.
- The second driver actually performs those functions on the media. This
- approach enables MS-DOS to treat flash memory as an ordinary drive in a
- system, allowing users to gain instant access to the media and store data
- in applications just as they would in a desktop PC. The second driver is
- also hardware specific and OEMs can easily modify it to support the
- specific flash memory implementation for their mobile computing systems.
-
- Release of Media Control Structures Supports Flash Standard
-
- By releasing the Microsoft Flash File System media control structures to
- the industry, Microsoft is making it easier for the industry to adopt a
- common format to manage, read and write data on flash memory, much as the
- MS-DOS File Allocation Table (FAT) manages data on magnetic media --
- floppy disks -- used with products from thousands of PC hardware and
- software vendors. The standard file format will allow users to interchange
- flash memory cards with any PC they choose -- even operating systems not
- based on MS-DOS, for example, provided those operating systems support the
- media control structures.
-
- The public release of the media control structures enables all applications
- and system software developers to use them without royalty, license or
- other cost. In addition, the common file format can decrease development
- cost for software vendors by reducing the need to support multiple file
- formats for flash memory.

- Founded in 1975, Microsoft (NASDAQ "MSFT") has become the worldwide leader
- in software for personal computers. The company offers a wide range of
- products and services for business and personal use, each designed with
- the mission of making it easier and more enjoyable for people to take
- advantage of the full power of personal computing every day.
