Cache (32-bit busmaster) is a standard feature that can provide
enhanced DASD performance as well as the ability to attach up to
seven Small Computer System Interface (SCSI) devices from a single
adapter.  Four DASD bays are provided, one of which can accommodate
5.25-inch half high and the other three support 3.5-inch DASD
devices.  Two bays are available for expansion such as a fixed disk,
CD-ROM, floppy disk drive and tape backup.  Three additional 32-bit
micro channel expansion slots are available for a wide range of
additional functions such as connectivity capability, attaching other
I/O devices, and/or coprocessor adapters.  Two Direct Memory Access
(DMA) serial ports and one DMA parallel port are provided as
standard.  The PS/2 Model 90 XP 486 also provides a unique ability to
boot from any drive and an easy upgrade to Basic Input Output System
(BIOS) capability.
       The PS/2 Model 90 XP 486 Model 0KD features the 33MHz 80486
microprocessor with 320 million bytes (320MB) of fixed disk storage.
The Models 0J5 and 0J9 include the 25MHz 80486 and 80 million bytes
(80MB) and 160 million bytes (160MB) of fixed disk storage,
respectively.  The processor includes an internal memory cache
controller, an internal 8KB memory cache and an internal floating
point processor unit.
       IBM is enhancing its option product line by announcing the IBM
Personal System/2 5.25-Inch Slim High Diskette Drive

DESCRIPTION
INVESTMENT PROTECTION
The PS/2 Model 90 XP 486 systems are a family of very powerful
desktop computers that combine high-speed processor performance,
advanced graphics support and enhanced expandability.
       The customer's investment is protected by PS/2 Model 90 XP 486
in a variety of ways:
o   The PS/2 Model 90 XP 486 system is built on IBM's Micro Channel
    architecture providing compatibility with wide range of existing
    Micro Channel hardware and software applications.
o   Built on the Micro Channel architecture, the PS/2 Model 90 XP 486
    includes a unique processor complex that contains the 80486
    processor chip and associated functions.  The processor complex
    can be easily upgraded from 25MHz to the more powerful 33MHz
    system.  This capability provides investment protection and
    flexibility for the end user.
o   The PS/2 Model 90 XP 486 system is designed to provide four
    internal DASD bays and four 32-bit Micro Channel I/O slots (one
    slot is used for the IBM Personal System/2 Micro Channel SCSI
    Adapter with Cache, leaving three available for future
    expansion).  Up to 960 million bytes of internal storage
    capability is provided by the PS/2 Model 90 XP 486.  The IBM
    Personal System/2 Micro Channel SCSI Adapter with Cache allows up
    to seven SCSI devices to be attached to the PS/2 Model 90 XP 486
    (maximum three SCSI fixed disks are supported internally).  The
    PS/2 Model 90 XP 486 also supports an internal 5.25-inch diskette
    device.
o   The PS/2 Model 90 XP 486 system supports up to 32MB (1) of memory
    on the planar, eliminating the need for a memory adapter in the
    expansion slots.
 (1) Refer to the Programming Requirements and Limitations sections.
USER PRODUCTIVITY
User productivity is greatly enhanced by the many features of the
PS/2 Model 90 XP 486:
o   The powerful 80486 processor operating at 33MHz or 25MHz speed
    (80486 contains 8KB of internal cache and memory cache controller
    along with floating point processor built-in)
o   Faster SCSI DASD devices
o   Faster memory:  The PS/2 Model 90 XP 486 memory subsystem has
    been designed for optimum performance with interleaved memory,
    and features parity memory checking for added reliability and
    data integrity.  All system memory (up to 32MB) is supported on
    the system board, eliminating the need for a memory adapter in
    one of the expansion slots.  The system board has a total of
    eight memory sockets, two of which are used by a pair of 2MB
    Single In-Line Memory Modules (SIMMs) to provide the standard 4MB
    of memory. Optional 1MB, 2MB and 4MB memory SIMMs (70, 80 and 85
    nanosecond only) are supported in matched pairs to provide
    various memory configurations up to 32MB.  Although 80ns and 85ns
    memory SIMMs are supported, 70ns memory SIMMs provide optimum
    memory subsystem performance.
o   Graphics:  Enhanced graphics functions and performance make the
    PS/2 Model 90 XP 486 an ideal system for the display requirements
    of image, design and publishing applications. The integrated XGA
    provides 1024 x 768 x 16 colors, or 640 x 480 x 256 colors as
    standard and can be optionally expanded to 1024 x 768 x 256
    colors with the addition of one PS/2 Video Memory Expansion
    Option (#4007). XGA supports all VGA modes and it is optimized
    for use with window managers and other Graphical User Interfaces,
    allowing for highly interactive pop up icons and pull down menus.
    XGA also provides hardware support for 132 character text mode
    (using 8515 or 8514 display) and 16-bit direct color mode (64K
    colors at 640 x 480 resolution).  Micro Channel expansion slot #3
    of the PS/2 Model 90 XP 486 system contains a video feature bus
    connector that can be used to install a video adapter.
o   Selectable boot feature and licensed Systems Programs:  The PS/2
    Model 90 XP 486 provides another unique feature called selectable
    boot.  The customer can change the default boot sequence (for
    example, boot first from 'A' drive then 'C' drive, and load
    BASIC).  The customer can boot or load a program from the
    optional 5.25-inch internal diskette drive as if it were the 'A'
    drive.
o   Serial/parallel ports:  Other unique features of the PS/2
    Model 90 XP 486 include the dual Direct Memory Address (DMA)
    serial ports, and a DMA parallel port included as a standard
    feature. One of the serial port connectors is standard 25-pin D
    shell, and the other connector is 9-pin D shell.  The 9-pin D
    shell connector requires feature number 0217 or 0242 for
    attaching devices with 25-pin D shell connectors.
           The DMA serial port provides support for speeds from 300
    bits per second to 345.6K bits per second. It provides extensive
    function for various communication protocols, and reduces
    processor loading and overhead when used in higher speed
    communications. Speeds up to 345.6K bits per second are supported
    using IBM Enhanced EIA-232-D which requires a special shielded
    cable up to 20 feet long.
SYSTEMS MANAGEMENT
The PS/2 Model 90 XP 486 is well suited for customers who require
business solutions that will simplify the management of their data
processing systems.  Key features of the Model 90 to satisfy these

STATEMENTS OF DIRECTION:
o   IBM intends that a 32-bit version of OS/2 will support the full
    memory capability of the PS/2 Model 90 XP 486.
o   IBM intends to support the PS/2 Model 90 XP 486 systems with the
    AIX PS/2 operating system.
o   IBM intends to provide support under OS/2 for the Audio Visual
    Connection with the Extended Graphics Array (XGA) at 640 x 480
    resolution with 256 colors.
COMPATIBILITY:  The PS/2 Model 90 XP 486 contains licensed System
Programs that include BIOS, set configuration and features, test,
copy an option diskette, backup/restore and update System Programs.
These licensed System Programs are stored in a three million byte
protected partition on the fixed disk drive.  The Initial Machine
Load (IML) loads the BIOS program from the fixed disk drive into
system memory.  BIOS provides the hardware instructions and
interfaces required to support the standard features of the PS/2
Model 90 XP 486 and maintains compatibility with many software
programs currently operating under DOS and OS/2 on the Personal
Computer XT (TM), Personal Computer AT (R), and the PS/2 family.
However, due to the higher speed of the 80486 processor in the
Model 90 XP 486 systems, some timing sensitive software may require
modification.
       The PS/2 Model 90 XP 486 Reference Diskette contains an update
program (DISK386.SYS) and an installation program.  The update
program maintains compatibility between SCSI devices, IBM DOS and
some of the following types of programs that assume the fixed disk
drive will utilize the system Direct Memory Access (DMA) controller:
o   Multitasking DOS programs
o   Programs written for the 80386 microprocessor only
o   Programs that use the virtual 8086 mode of the 80386
    microprocessor
o   Programs that emulate expanded memory specification (EMS) in
    extended memory.
       The update program should only be installed when applications

providing DOS and/or memory extensions fail to work properly.  For
example, an application may fail to load and return the DOS prompt or
when attempting to access a SCSI device, the system may hang or the
screen may go blank.
       With this update program installed, a buffer is provided in
the first megabyte of system memory, which serves as an intermediate
location for data being transferred between the SCSI adapter and the
requesting program buffer.  While this update program allows
applications that utilize the system DMA controller to run, some
performance degradation in file access time may be experienced.  Only
after problems have been experienced, and the performance
implications considered, should this update program be utilized.
       The Extended Graphics Array (XGA) is designed to be compatible
with applications written to the following interfaces:
o   IBM VGA hardware interface in all operating environments.  There
    are minor differences between the IBM VGA hardware interface and
    the XGA hardware support of the VGA interface.  However, these
    differences are not expected to affect any applications.
o   Adapter Interface (AI) of 8514/A under DOS.
o   OS/2 Presentation Manager (TM) of 8514/A.
o   OS/2 DOS Compatibility Box in VGA modes.
       XGA does not support the applications written to:
o   8514/A hardware registers
o   AI of 8514/A under OS/2.
       For additional information on XGA, refer to Product
Announcement 190-182, dated October 30, 1990.

LIMITATIONS:  The PS/2 Model 90 XP 486 supports a maximum of 32MB of
memory, 16MB of which are addressable by DMA.  The PS/2
Model 90 XP 486 supports 1MB, 2MB and 4MB memory SIMMs (70, 80 and 85
nanosecond only).  However, because of interleaved memory, memory
SIMMs must be installed in a matched pair (for example, two 1MB SIMMs
or two 2MB SIMMs).
       The PS/2 Model 90 XP 486 systems with more than 8MB of memory
should be installed using Reference Diskette Version 1.02 or higher.
To obtain the latest version, call 1-800-426-7282, weekdays between
8 a.m. and 8 p.m., Eastern Standard time.  Specify the diskette for
IBM Personal System/2 Model 90 XP 486 (57F1952).  In Canada, call
1-800-465-1234 weekdays between 8 a.m. and 4:30 p.m. Eastern Standard
time.  In Alaska, call (414) 633-8108.
NOTE: These instructions apply to United States and Canadian
customers only.  Customers outside of the United States and Canada
should follow local support procedures.
       Refer to PROGRAMMING REQUIREMENTS section for operating
systems limitations.
       The licensed System Programs include BIOS, set configuration
and features, copy an option diskette, test, backup/restore and
update System Programs.  These licensed System Programs are stored in
a three million byte protected partition on the fixed disk drive.
The formatted capacity is therefore reduced by three million bytes,
and the total user accessible capacity may vary slightly based on
operating environments.  This protected partition is not affected
when the drive is formatted using the Format command in DOS or OS/2.
The licensed System Programs are also provided on the PS/2
Model 90 XP 486 Reference Diskette.

SECURITY, AUDITABILITY AND CONTROL
       Security and auditability features of this product are:
o   A mechanical lock to allow the user to lock the system cover
o   Power-on Password used to prevent the use of the system by

    unauthorized persons
o   Set Keyboard Password used to lock the keyboard without turning
    the system off
o   Set Network Server Mode allows the system keyboard to be locked
    to all entries except the password and at the same time allow
    other computers on the network to access the fixed disk.
       Small Computer System Interface (SCSI), as defined in the
American National Standard Institute (ANSI) standard X3.131-1986,
provides a port for the attachment of external devices.  The IBM PS/2
SCSI Adapter is in conformance with this standard and has an external
port.
       A data security exposure exists, even with Power-On Password
installed, since external SCSI controllers can attach through the
external SCSI port and gain undetected read or write access to data
stored on internal and external SCSI devices.
       Physical access to the system and external SCSI devices must
be controlled to limit this exposure.
       User management is responsible for evaluation, selection and
implementation of security features, administrative procedures and
appropriate controls in application systems and communications
facilities.
