IBM 8238 Token Ring Stackable Hub ********************************* "BRONZE" Base Operational Microcode VERSION 1.03 ********************************* Version 1.03 of the BRONZE level for the IBM 8238 TR Stackable Hub Model AB1 or PB1 base unit operational microcode along with the current levels of boot microcode for the base units and the operational and boot microcode for the expansion units. V1.03 is to be used to upgrade 8238 model AB1 and PBS1 with operational microcode currently at V1.02. It may also be used to re-load operational microcode on Model AB1 or PB1 base units with V1.03 that are suspected to have microcode problems. Version 1.02 of the BRONZE base unit operational code is a prerequisite for V1.03 BRONZE microcode. Download 8238B103.EXE to your PC and then execute by entering: 8238B103 (path) at the DOS prompt. The following files will be written in the specified directory (or diskette). Readme.103 * ASCII text file BOBV1030.BIN * Base operating code, BRONZE BB_V1010 BIN * Base Boot code. EO_V1010 BIN * Expansion Unit Operational code. EB_V1000 BIN * Expansion Unit Boot code. Relnote 103 * Release Notes, ASCII file.
