IBM PS/2 Blue Lightning Processor Upgrade FRU P/N 13H6701 MKT P/N OP7080Y The Blue Lightning Processor replaces the 80386DX microprocessor on the system board and emulates the presence of the original 80386DX, so no special software is required. The Blue Lightning Processor Upgrade is fully compatible with operating systems that are capable of running on an 80486 microprocessor. (incl. OS/2 and DOS) It also supports bus mastering adapters, if they are present in the system. Important Always run the DIAGNOSTIC TESTs with the Blue Lightning Processor Upgrade cache disabled. (BANK-1 SW-1 OFF = cache disable for testing purposes !) In some cases, with the Blue Lightning installed, the diagnostic tests might indicate an error. Try to replace the Upgrade board with the origin 386DX. If the diags are OK the adapter is fully functional and will also work with the Blue Lightning Upgrade. This Processor update can be installed on one of the following computers. 8570, 8580 with 80386 Microprocessor. You must use 8570/80 Reference Diskette Version 1.10 or later. The upgrade kit contain: Blue Lightning Processor Upgrade board 132-Pin PGA Socket Extender (only needed for 8580 mod. 111, 121, 311 or 321) Processor removal tool Utility Diskette Label (POWERED BY BLUE LIGHTNING) Default Switch settings are: +---------------------------------------------+ |Switch Bank 1 |SW-1|SW-2|SW-3|SW-4| | | |---------------+----+----+----+----+----+----| | |ON |Off |Off |Off | | | |---------------+----+----+----+----+----+----| |Switch Bank 2 |SW-1|SW-2|SW-3|SW-4|SW-5|SW-6| |---------------+----+----+----+----+----+----| | |ON |ON |ON |Off |ON |Off | +---------------------------------------------+ Switch Bank 1 function +----------------------------------------------------------------------------+ |SW # |Setting |Controls |Remarks | |-----+--------+------------------------------+------------------------------| | 1 | ON (D) |Cache on at startup |this switch is only read at | | | Off |Cache off at startup |Power-ON. | |-----+--------+------------------------------+------------------------------| | 2 | ON |Flush cache on INT 9 |- | | | Off (D)|Do not flush cache on INT 9 | | |-----+--------+------------------------------+------------------------------| | 3 | ON |Flush cache on INT 10d |- | | | Off (D)|Do not flush cache on INT 10d | | |-----+--------+------------------------------+------------------------------| | 4 | ON |Flush cache on INT 11d |- | | | Off (D)|Do not flush cache on INT 11d | | +----------------------------------------------------------------------------+ Switch Bank 2 function +----------------------------------------------------------------------------------+ |SW # |Setting |Controls |Remarks | |-----+--------+------------------------------+------------------------------------| | 1 | ON (D) |Flush cache on INT 14d |- | | | Off |Do not flush cache on INT 14d | | |-----+--------+------------------------------+------------------------------------| | 2 | ON (D) |Fast RAM count |This switch caches the read-only | | | Off |Slow RAM count |(ROM) from the adapters.

Power-OFF the computer 2. Remove the Power-Cable 3. Open/lift the Machine cover 4. Remove Hard Disk(s) / Adapters (so you can freely operate with the already installed Microprocessor) 5. Locate the Processor on the System Board (Pin 1) 6. Remove the Processor (80386) 7. If the machine is a 8580 mod 111 121 311 or 321 then install the 132-Pin PGA socket Extender (Pin-1 to Pin-1) 8. Install the Blue Lightning Board into Processor/PGA socket (be sure PIN-1 to Pin-1) 9. If your machine have an SCSI Adapter, then on Switch Bank 2 / SW-6 must be set to ON. 10.Reinstall all previously removed Cable/Adapter 11.Reconnect the Power cord 12.Power-ON the system Utility Diskette To control the cache speed under OS/2 or DOS (but not a DOS session under OS/2) without restarting the computer, insert the Utility Diskette in drive A and at the prompt: 1. Type A: to change to the root directory of drive A. 2. Type slow to disable the Blue Lightning cache --- or --- Type fast to enable the Blue Lightning cache. To permanently affect caching options, use SW-1 on bank 1.
