IBM PS/2 ENHANCED 486/50 PROCESSOR UPGRADE OPTION IBM Announcement Letter Number 192-101 dated April 28, 1992 IBM US - Last Revised on April 28, 1992 Brief Description of Announcement, Charges, and Availability The Personal System/2 (R) (PS/2 (R)) Model 90 XP 486 (8590) and Model 95 XP 486 (8595) family of systems can be upgraded by the new PS/2 Enhanced 486/50MHz Processor Upgrade Option. This option allows current users of the 8590 and 8595 to obtain the higher performance and improved reliability, availability and serviceability (RAS) afforded by error checking and correction (ECC) memory. In addition, it implements the 40MB/second streaming data introduced on the 8595-0MF and -0MT providing significant high-speed data transfer performance improvements when using adapters with streaming data support. Better system performance and more efficient memory utilization are afforded through Enhanced Memory Optimization between memory and the Micro Channel (R). The Intel i80486 (1) 50MHz microprocessor includes an internal memory cache controller, 8KB memory cache and an integrated floating-point processor unit. Additionally, an external 256KB level-two cache is provided on the processor complex as a standard feature. Memory must be either all ECC or all parity and must be installed in matched pairs of the same size, type and speed. Planned Availability Date: July 31, 1992.

TECHNICAL INFORMATION SPECIFIED OPERATING ENVIRONMENT MACHINE REQUIREMENTS: The PS/2 Enhanced 486/50 Processor Upgrade Option can be installed in PS/2 Models 90 XP 486 and 95 XP 486 systems only in the specified processor complex slot on the system board. When upgrading to the Enhanced 486/50MHz Processor Upgrade, system memory must consist of matched pairs since the enhanced 486/50 processor complex requires interleaved memory. The Enhanced 486/50MHz Processor Upgrade supports 70, 80 and 85ns parity and 70ns ECC memory, but memory cannot be of mixed types. Memory SIMMs may be of different speeds and sizes but must be installed in matched pairs. The PS/2 Enhanced 486/50 Processor Upgrade Option requires a unique reference diskette identified by a "3" on the label. The diskette is shipped with the processor upgrade option. PROGRAMMING REQUIREMENTS: The following operating systems support the PS/2 Enhanced 486/50 Processor Upgrade Option when it is installed in the PS/2 Model 90 XP 486 and PS/2 Model 95 XP 486: o OS/2 (R) Standard Edition (OS/2 SE) Version 1.30.2 (1) o Operating System/2 (R) Version 2.0 (1) o OS/2 Extended Edition (OS/2 EE) Version 1.30.2 (1) o DOS Version 5.0 (2) o DOS J5.02/V o AIX (R) PS/2 Version 1.2.1 (3) o IBM 4680 Operating System Versions 2 and 4 o Novell NetWare (4) v2.2 and v3.11 (when certified by Novell; testing is not complete). (R) Registered trademark of International Business Machines Corporation. (1) OS/2 SE, OS/2 EE Version 1.30.2 and OS/2 Version 2.0 supports up to 24 fixed disks. (2) DOS 5.0 supports up to seven fixed disk devices and additional SCSI devices (up to a total of 24) in a system. (3) AIX PS/2 Version 1.2.1 (with the application of PTF #P211300) will exploit the PS/2 Enhanced 486/50 Processor Upgrade Option when installed in PS/2 Model 90 XP 486 and PS/2 Model 95 XP 486. (4) Trademark of Novell, Incorporated. All of the above operating systems provide support for up to 16MB of memory on the PS/2 Model 90 XP 486 and PS/2 Model 95 XP 486. However, OS/2 2.0, AIX PS/2 Version 1.2.1 (with the application of PTF #P211300), SCO (5) UNIX (6) System V/386 Version 3.2v4.0 and Novell NetWare v2.2 and v3.11 operating systems provide support for greater than 16MB of memory on the PS/2 Models 90 XP 486 and 95 XP 486.

COMPATIBILITY: The IBM Personal System/2 Enhanced 486/50MHz Processor Upgrade Option is designed to maintain compatibility with many software programs currently operating under DOS and OS/2 on the Personal Computer XT (TM), AT (R) and the PS/2 family. The PS/2 Models 90 XP 486 and 95 XP 486 contain licensed System Programs, which include set configuration and features, test, copy an option diskette, backup/restore and update system programs. Licensed System Programs are stored in a 3MB (three-million byte) protected partition on the fixed disk drive. The IML loads the BIOS program from the fixed disk drive into system memory. BIOS provides the hardware instructions and interfaces designed to support the standard features of the IBM PS/2 Models 90 XP 486 and 95 XP 486 and maintain compatibility with many software programs currently operating under DOS and OS/2 on the IBM PC XT, IBM AT and the IBM PS/2 family. However, due to the higher speed of the 80486 processor on the new processor complex, some timing-sensitive software may require modification. The PS/2 Model 90 XP 486 and Model 95 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 that serves as an intermediate location for data transferred between the SCSI adapter and the requesting program's 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. NOTE: The upgrade does not change features and options supported by the base machine (refer to the List of Supported Products section of the Sales Manual or contact your IBM representative). (TM) Trademark of International Business Machines Corporation. (R) Registered trademark of International Business Machines Corporation. LIMITATIONS: Only one processor complex at a time may be installed in a PS/2 Models 90 XP or 95 XP. The PS/2 Enhanced 486/50 Processor Upgrade Option supports a maximum of 64MB of ECC or parity memory, addressable by DMA. The PS/2 Enhanced 486/50 Processor Upgrade Option supports 1MB and 2MB 85ns memory, 2MB, 4MB and 8MB 80ns memory and 4MB and 8MB ECC 70ns memory. The memory SIMMs must be installed in matched pairs (speed, size and type). Refer to he the PROGRAMMING REQUIREMENTS section for operating systems limitations. The licensed system programs includes set configuration and features, copy an option diskette, test, backup/restore and update System Program. These licensed System Programs are stored in 3MBs of protected partition on the fixed disk drive. The formatted capacity is reduced by 3MBs 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. The licensed system programs are also provided on the reference diskette that comes with the PS/2 Enhanced 486/50 Processor Upgrade Option. The following Micro Channel adapters and options are not supported by the PS/2 Enhanced 486/50 Processor Upgrade Option: o IBM PS/2 3.5-inch 2.88MB Slim-High Diskette Drive (#1106, 6451106) o IBM PS/2 256KB Level 2 Cache Option (1098, 6451095). High-performance BIOS uses 128KB of system memory.
