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.
