- IBM PS/2 MODEL 56 SLC (059), MODEL 57 SLC (059) AND MODEL M57 SLC
- (259) UPGRADES TO 8MB OF STANDARD MEMORY
- IBM is enhancing the standard system memory to 8MB on PS/2 (R)
- Model 56 SLC (TM) (8556-059), Model 57 SLC (8557-059) and
- Model M57 SLC (8557-259) systems, effective July 21 1992. With these
- changes, all enhanced systems have double the standard system memory
- to better address customer application requirements.
- The PS/2 Model 56 SLC, Model 57 SLC and Model M57 SLC systems
- include Operating System/2 (R) (OS/2 (R)) Version 2.0 (preinstalled
- in the 059 models, and included with the 259 model). A 160MB fixed
- disk and OS/2 2.0 combine for a functionally adaptive,
- high-performance desktop system with a hardware platform conducive to
- solutions for a broad range of customer requirements.
- These selected PS/2 Model 56 SLC, Model 57 SLC and
- Model M57 SLC systems are shipped with two 4MB, 70ns single in-line
- memory modules (SIMMs) and allow up to 16MB 70ns memory on the
- planar. The memory controller automatically supports enhanced
- performance via memory interleaving with the appropriate memory
- configurations.
- Planned Availability Date: July 21, 1992.

- OVERVIEW HIGHLIGHTS
- o Concurrent execution of more applications with additional 4MB of
- memory in the PS/2 Model 56 SLC (059), Model 57 SLC (059) and
- Model M57 SLC (259) systems
- o No additional cost to customer
- DESCRIPTION
- USER PRODUCTIVITY
- The increased standard memory to 8MB on the selected PS/2
- Model 56 SLC, Model 57 SLC and Model M57 SLC systems provides the
- capability to support more applications concurrently, at no
- additional cost to the customer. The additional memory better
- enables the standard configurations to support the demands of
- advanced operating systems and applications.
- The enhanced PS/2 models (8556-059, 8557-059 and 8557-259)
- have 8MB standard memory, with parity, using two 4MB 70ns SIMMs. The
- system board has one unused memory socket to allow the system board
- to be populated to a maximum of 16MB.
- INVESTMENT PROTECTION
- These selected PS/2 Model 56 SLC, Model 57 SLC and Model M57 SLC
- systems can be upgraded using the previously announced PS/2 486SLC2
- Processor Upgrade (#2310, 32G3606) option when it becomes available.
- TECHINFO TECHNICAL INFORMATION
- SPECIFIED OPERATING ENVIRONMENT
- Technical information remains unchanged from previous
- announcements of the PS/2 Model 56 SLC (059), PS/2 Model 57 SLC and
- PS/2 Model M57 SLC (259).
- LIMITATIONS: The PS/2 Model 56 SLC (059), Model 57 SLC (059) and
- Model M57 SLC (259) systems support only 2MB, 4MB and 8MB 70ns SIMMs.
- To take advantage of enhanced performance via interleaved memory,
- SIMMs should be installed using all 2MB or all 4MB SIMMs. One, two
- or three 2MB SIMMs provide memory interleaving. Two or three 4MB
- SIMMs also provide memory interleaving. The 8MB SIMMs do not provide
- interleaving.
- With 24-bit addressing, the maximum addressable memory space
- is 16MB. The system reserves 128KB of memory when BIOS/POST is
- copied to random access memory (RAM) for execution in systems with
- less than 16MB of planar memory. The system reserves 1.375MB of
- memory in systems with 16MB of planar memory.
- The licensed System Programs include BIOS, set configuration
- and features, copy an option diskette, test, backup/restore and
- update system program. These licensed System Programs are stored in
- 3MB of protected partition on the fixed disk drive. The formatted
- capacity is therefore reduced by 3MB, and the total user-accessible
- capacity may vary slightly based on operating environments. This
- partition is not affected when the drive is formatted using the
- FORMAT command provided in DOS or OS/2.
- ORDERING TERMS AND CONDITIONS
- The terms and conditions for the 8556 and 8557 system units
- are unaffected by this announcement.
