Hardware Design Guide for Microsoft Windows 95

Note PC 95 refers to a platform designed to be the minimum standard PC for
Microsoft® WindowsTM 95 during 1995. By early 1995, almost all new PCs are
expected to meet these criteria.

The PC 95 is a new platform consisting of three key elements—a minimum set of
hardware features, Plug and Play components, and Windows 95. This platform
provides the user with a PC that is easy to use and configure. In a sense, it offers the
power of a PC without the hassles commonly associated with complex devices.
With the PC 95, complexities are handled internally; the user sees only a device
that is as easy to use as any other appliance in the home.
This chapter introduces the PC 95, discusses its costs and benefits, and describes
the relationships between the hardware, Plug and Play, and Windows 95.
The PC 95 requirements defme the basic hardware platform necessary to qualify
for the Microsoft® Windows" 95 Logo. The logo also indicates that Windows 95
is preinstalled and has passed the Microsoft Windows 95 Hardware Compatibility
Tests (HCT), so users will not have to worry about hardware and software compatibility. For more information about meeting the requirements for the Windows 95
Logo program, contact the Microsoft Compatibility Labs (MCL) at 206-635-4949.

What Is a PC 95?
The PC 95 is the physical reali7ation of the concept that the power of computers
should extend to the ordinary user. Combining the advantages of the Plug and Play
hardware and software architecture, the standardized features of the PC hardware
design, and the easy-to-use, attractive interface of Windows 95, the PC 95 establishes a new standard. It is simple, versatile, and usable.

Chapter 1 The PC 95

The PC 95 also specifies as standard certain features that have only been options, in
the past. Users and software developers can count on the availability of these
standard features, making product design and purchase decisions easier.
Baseline PC systems have evolved incrementally over the years. The basic PC was
defined in 1981 with the shipment of the IBM® PC. Many advances since then have
become standard, including the 16-bit AT® bus, VGA display technology, and the
386 (80386) CPU architecture. A number of optional features have also increased
in popularity, notably, audio, CD-ROM, small computer system intelface (SCSI),
modems, mice, and alternate expansion buses such as the Peripheral Component
Interconnect (PCI) bus and the Personal Computer Memory Card International
Association (PCMCIA) bus. The arrival of Windows 95 is an opportunity to raise
the standard for what users and manufacturers expect in a basic PC.
The PC 95 represents the current standard for a Windows 95—based PC, the next
logical step in this evolution. The PC 95 provides hardware specifically designed
and optimized for both Plug and Play and Windows 95.

Plug and Play
The Plug and Play initiative is a set of hardware and software specifications that
define a minimum Plug and Play system. Implementations of these specifications
are found throughout the PC 95, including a Plug and Play BIOS, Plug and Play
methods of identifying and configuring hardware resource requirements for expansion cards and peripherals, and operating system software that recognizes and uses
the Plug and Play features of the system.
A Plug and Play system contains a Plug and Play BIOS that identifies and
configures the integrated resources on the PC system. For example, the system
BIOS identifies motherboard devices such as parallel ports and display adapters,
and allocates their resources.
Expansion cards and peripheral hardware must also be designed to implement the
Plug and Play specifications. This guide includes the design criteria for Plug and
Play expansion devices and peripheral hardware in addition to the descriptions of
hardware requirements and recommendations for the PC 95.
Plug and Play software, such as Windows 95, uses the features of Plug and Play
hardware to identify the resources of all devices in the system, including attached
peripherals such as Plug and Play printers. When the software "knows" the system
resources, it can use the unique features of each device, optimizing system
performance.

Hardware Design Guide for Microsoft Windows 95

The Windows 95 Operating System
Windows 95 is one of the most significant updates yet to the core Windows product
line. Windows 95 offers compatibility with existing applications while introducing
many easy-to-use features that increase productivity.
Plug and Play is one of the key ways in which Windows 95 enhances ease of use.
Windows 95 fully supports all of the configuration management, resource arbitration, and device enumeration functions defined in the Plug and Play specifications.
Windows 95 enumerates the PC system devices (by retrieving identification from
the devices), places the information in a system data structure called the hardware
tree, and determines the resources available on each of the devices. Windows 95
also examines the resources for all of the devices, configures the devices so they
don't conflict with one another, and loads the appropriate device drivers.
In essence, Windows 95 performs a dynamic configuration of the system using only
the resources and device drivers requested by the system devices. If the configuration of the system changes—for example, if a portable PC is plugged into a
docking station with a SCSI host adapter—Windows 95 reenumerates the system,
reconstructs the hardware tree and device resource information with the new capabilities of the SCSI host adapter, and loads the appropriate device driver for the new
device. Hardware designs that allow flexible allocation of all of the resources on
the PC enhance the dynamic nature of Windows 95.
Windows 95 maintains backward compatibility in a number of ways with older,
non–Plug and Play systems. Windows 95 can be used on an older PC that is not
Plug and Play enabled, and will attempt to identify the devices and resources that
are available. If a device driver is available for the older hardware, Windows 95
identifies the driver and loads it.
Windows 95 supports the changing hardware resources of docking mobile systems
by examining the system hardware and, often, automatically choosing the correet
configuration. For example, a multiconfiguration portable PC might have two states
called "docked" and "undocked." Undocked might mean, for example, no network
adapter or audio adapter. The Windows 95 detection routine calls the system BIOS,
determines the system configuration state, then selects the proper hardware profile
and loads the appropriate device drivers for the current system configuration. The
docking station can also change this state by generating dynamic docking and
undocking events.
Windows 95 also enables more cooperative behavior between applications. Each
time Windows 95 identifies a change in the system, it notifies applications—for
example, switch on battery power, establish fast network connection, or switch to
low-resolution display. With this capability, applications can make smart decisions
based on the new information, such as stop background reformatting, download all
new mail messages, use smaller fonts, or determine network identifier based on the
user's location and the available hardware.

Chapter 1 The PC 95

7

Windows 95 also supplies an increased amount of useful information about the PC
system configuration, for example, the identities and allocated resources of the
devices attached to the system.
The availability in Windows 95 of dynamic configuration, PCMCIA support, warm
docking or hot docking, and other new capabilities creates many opportunities for
new business products, better hardware, and new applications for the PC 95.
The PC 95 concept means increased ease of use and more flexible hardware
configuration for users. But Windows 95 is also designed to run well on almost
any PC-compatible system that runs Microsoft® Windows 3.1 in enhanced mode
and has a 386 or later microprocessor, at least 4 MB RAM, and a VGA display.
In fact, although this configuration represents the minimum PC capable of running
Windows 95, it will typically run the user's existing applications better than
Windows 3.1, and will be a good fit for users who are upgrading their existing
operating system. These systems will not, however, offer all the benefits available
with a Plug and Play—enabled system.
This guide defines an improved baseline PC, or reference system, for running
Windows 95. With a common baseline system, users can count on a minimum set of
features with any PC purchase, applications can begin to rely on these features, and
the industry as a whole will benefit.

The New Hardware Standards
The PC 95 concept sets a baseline minimum hardware standard for the next
generation of PCs. This standard includes hardware requirements for a variety of
different PC systems and peripherals. The resulting base system meets the
requirements of Plug and Play and is easy to use and configure.
This list is an overview of some of the requirements for a desktop PC 95. (It is not
a complete list.)
