IBM IntelliStation/IBM PC - Configuring ISA adapters in a system with a PCI adapter already installed
Applicable to: World-Wide
Purpose:
This article describes how to configure IBM PC/IBM IntelliStation systems to use ISA adapter cards in conjunction with PCI adapter cards.
Procedure:
Perform the following steps prior to installing an ISA (non-'plug-and-play') adapter card into an IBM PC/IBM IntelliStation system containing a PCI adapter card.
1. Check the documentation that accompanies your ISA adapter card to determine what system resources it requires. The resource requirements that need to be noted include shared memory address range, I/O address, DMA assignments, and IRQ assignments.
2. Power on the system.
3. Press the F1 key when the memory count first appears (A symbol will appear in the upper right corner of the screen). This will take you into the System Configuration utility.
4. Select ISA Legacy Resources from the Configuration Utility main menu.
5. Work through the ISA Legacy Resources menu step by step, selecting each system resource required by your ISA adapter card so that it is set to Unavailable. Setting ISA resources to Unavailable means that they have been made unavailable to PCI adapters and are therefore preserved/protected for exclusive use by your ISA adapter card(s).
Note: Shared memory required by ISA adapter cards MUST be set to Unavailable using multiples of 16KB even if the physical memory requirement is less than this. For example, to configure correctly for an IBM ISA 16 Token Ring adapter having the default 8KB ROM at CC000, set memory range CC000-CFFFF to Unavailable.
6. Check that at least one Interrupt level is left set as Available within ISA Legacy Resources so that PCI adapter(s) can configure. It is recommended that IRQ15 is left set as Available for this purpose.
7. Return to the Configuration Utility main menu when configuration of ISA Legacy Resources is complete.
8. Select Advanced Setup.
9. Select ROM Shadowing.
10. If your ISA adapter card contains ROM or uses a RAM buffer, disable ROM Shadowing for the address range used by the ISA adapter card. Each memory field within the ROM Shadowing menu is 32KB in size. For example, if the ISA adapter card contains a ROM that is 32KB in size and is located at D4000, disable ROM Shadowing at D4000- DBFFF.
11. When all setup is complete, press the ESC key repeatedly until an option to save the changes appears.
12. Save the changes and exit the Configuration Utility.
13. Your ISA adapter may now be installed and tested using the adapter diagnostics to ensure that the adapter will initialize and function properly.
