           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
           (#1066, 6451066).  This device is an internal 5.25-inch, 1.2MB

                  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.

           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.

              Corporation.
           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.
