NETWORK SUPPORT
The PS/2 53LS 486SLC2 (9553-1BX) supports Ethernet Version 2 and IEEE
802.3 (CSMA/CD) interfaces, and data transfers at 10Mbps via 10Base-T
(twisted-pair) or through the Attachment Unit Interface (AUI)
connection.  Data transfers via 10Base2 (thin cable), 10Base5 (thick
cable), or a fiber optic cable can be accomplished through the AUI
connection and a user-provided external transceiver.
       The PS/2 53LS 486SLC2 (9553-2BX) supports a 4Mbps or 16Mbps
token-ring local area network attached to an appropriate file server
supporting remote initial program load if an optional diskette or
fixed disk has not been installed.
POWER MANAGEABLE DISPLAY
Power-manageable displays that conform to the Video Electronics
Standards Association (VESA) Display Power Management Signaling
(DPMS) interface can use the DPMS-enabled BIOS utility package to
save power.  The utility instructs power-manageable displays to go
into various power-saving states after a period of user inactivity
has been detected.  DPMS puts power manageable displays into one of
three different states:
1.  Standby:  Minimum power savings but immediate return to ON.  --
    Default activated after 15 minutes.
2.  Suspend:  Medium power savings but medium return to ON.  --
    Default activated after 30 minutes.
3.  Off:  Maximum power savings but noticeable delay in return to ON.
    -- Default activated after 60 minutes.  Timeout defaults can be
    set for from 1 to 99 minutes.
       After December 1993, the DOS and Windows DPMS utility package
may be obtained from:
o   IBM PC Company BBS at 919-517-0001
o   OS/2 (R) BBS accessed via ADVANTIS

COMPATIBILITY:  Refer to the 9553 Sales Manual pages or contact your
IBM representative for a complete list of supported features and
options and compatible IBM and vendor software.  The Sales Manual is
updated periodically.
       The system contains licensed system programs, which include
SurePath BIOS, set configuration and features, test, copy an option
diskette, backup/restore and update system program.  These licensed
system programs are provided on the 53 486SLC2 Reference and
Diagnostic Diskettes shipped with the system, models 9553-0B7 and
9553-0BB, or 53LS 486SLC2 LAN Administrator Diskette Package, models
9553-1BX and 9553-2BX, and are stored on the host.  The LAN
Administrator Package loads SurePath BIOS and system programs from
the host into system memory.  SurePath BIOS provides the hardware
instructions and interfaces designed to support the standard features
of the system and to maintain compatibility with many software
programs currently operating under DOS and OS/2 on the Personal
Computer XT (TM), Personal Computer AT (R) and the Personal System/2
(R) family.
       Due to the high level of integration and increased system
board memory capacity, features such as the PS/2 Micro Channel memory
adapter options are not supported.
LIMITATIONS:  The system may only be installed in the horizontal
position.  The total number of adapters is limited by the average of
1.6 amps per slot.
       The systems support only 2MB, 4MB and 8MB 70ns single in-line
memory modules (SIMM).
       With 24-bit addressing, the maximum addressable memory space
is 16MB.  The system reserves 128KB of memory when SurePath BIOS/POST
is copied to RAM for execution in systems with less than 16MB of
system board memory.  The customer will have 15.914MB (15936KB)
available when 16MB of memory is installed.
       The licensed system programs include SurePath BIOS, set
configuration and features, copy an option diskette, test,
backup/restore, and update system program.  The licensed system
programs are provided on the PS/2 53 486SLC2 Reference and Diagnostic
Diskettes.  High performance SurePath BIOS uses 128KB of system
memory.
       Display adapter cards that use the Auxiliary Video Extension,
when installed in a system, require installation in slot 1 and
attachment of a display to the system video connector during
configuration of the system.
       SCSI devices may only be external and require a SCSI adapter.
       The system requires ABIOS from Reference Diskette Version 1.1,
or later, to run OS/2.
       The Enhanced 2.88MB Diskette Drive's (#1272, 6451272)
electronic diskette eject button feature is supported.  The
software-controlled diskette eject feature and the ability to lock a
