Appendix C - IBM Memory Board Installation
This appendix describes how to install the 34F series of IBM memory boards on a PS/2 Micro Channel server. The model numbers of these PS/2 memory boards are 34F3077 and 34F3011. You can identify these boards by the position of the SIMM memory connectors: three on the left and one on the right.
When you configure a 34F-series memory board on a Micro Channel platform, configuration information from both the Banyan server software and the memory board is written to the same block (Block 0) on the server disk. The two workaround solutions in this appendix allow both sets of configuration data to be written to Block 0 without conflicts.
Depending on the setup of your server, use one of the following solutions:
Installing on a new server - This is a workaround for a new installation of Banyan server software on a Micro Channel platform that has been configured with a 34F memory board.
Installing on an existing server - This is a workaround for a server that already has Banyan server software installed. Use this solution if you are adding a new 34F memory board to the server, or if you are adding or removing a SIMM module from an existing 34F memory board.
Both solutions require the use of the Memory Board Option Diskette that is shipped from IBM with the memory board. This Option Diskette must be Revision 1.30 or greater.
Installing the Board During a New Installation
The following procedure details how to install Banyan server software in a Micro Channel platform that has a 34F-series board (with either 2 MB or 4 MB SIMMs):
1. Insert the Reference Diskette in drive A and boot the system.
2. Select Copy an Option Diskette from the Main Menu. Remove the Reference Diskette when you are prompted for the Option Diskette.
3. Insert the Memory Board Option Diskette in drive A and press ENTER. (The Option Diskette must be Revision 1.30 or greater.) Remove the Option Diskette.
4. Insert the Reference Diskette in drive A, and press ENTER to update it with the Memory Board option information.
5. Power off the system.
6. Plug the SIMM memory connectors onto the memory board, and add the board to your Micro Channel platform.
7. Reboot the Micro Channel platform.
8. Enter Y when a message prompts you to configure the system automatically.
9. Install the Banyan server software according to the instructions in Chapter 4 through Chapter 8.
10. After the Banyan server software is running, reboot the system using the Reference Diskette.
11. Select Set Configuration and then select Save Changes and Exit. At this point, the server software can recognize the additional memory that the expansion board provides.
12. Remove the Reference Diskette.
13. Boot the system from the server disk.
When the system powers up, it counts the base memory, tests the diskette drive and the fixed disk, and then tests the added memory. The added memory is not tested first because the configuration for it is on the fixed disk.
Installing the Board in an Existing Server
The following procedure details how to install a 34F-series board in an existing Banyan server. This procedure can be used on all certified Micro Channel systems with either 2 MB or 4 MB SIMMs.
In addition, use the following procedure when you add or remove one of the 34F boards, or when you add or remove memory from one of the boards:
1. Insert the Reference Diskette in drive A and boot the system.
2. Select Copy an Option Diskette from the Main Menu. Remove the Reference Diskette when you are prompted for the Option Diskette.
3. Insert the Memory Board Option Diskette in drive A and press ENTER. (The Option Diskette must be Revision 1.30 or greater.) Remove the Option Diskette.
4. Insert the Reference Diskette in drive A, and press ENTER to update it with the Memory Board option information.
5. Power off the system.
6. Plug the SIMM memory connectors onto the memory board, and add the board to your Micro Channel platform.
7. Reboot the Micro Channel platform.
8. Enter Y when a message prompts you to configure the system automatically.
9. Reboot the system with the Reference Diskette, and select the Set Configuration option.
When the system powers up, it counts the base memory, tests the diskette drive and the fixed disk, and then tests the added memory. The added memory is not tested first because the configuration for it is on the fixed disk.
