Resolving Memory Address Conflicts
Resolving Memory Address Conflicts
The automatic configuration program might change the memory address space used by some hardware and
software options. The new address might conflict with addresses defined for use through the expanded memory
specifications (EMS). (EMS memory is used only in the DOS environment.)
If a memory conflict exists, one or more of the following could occur:
- The system cannot load the operating system.
- The system is disabled.
- An application does not operate or it returns an error.
- Screen messages indicate that a memory address conflict exists.
You can resolve these conflicts in one of the following ways:
- Change the software configuration (primary method).
- Change the system configuration (alternate method).
Changing the Software Configuration
The best method of resolving memory address conflicts is to change the software
configuration by changing the address defined by the EMS driver.
For conflicts caused by XMA2EMS (DOS 4.0) or EMM386 (DOS 5.0) in
the CONFIG.SYS file, refer to the DOS documentation. For conflicts caused by an expanded memory
manager other than the one supplied with DOS, refer to the memory manager documentation.
NOTE: To view the addresses used by the installed hardware and
software options, go to the Main Menu, select Set configuration then
select Display memory map.
Changing the System Configuration
An alternative method of resolving memory address conflicts is to change the address of the conflicting
hardware option by selecting Change configuration from the Set configuration program.
Before changing adapter addresses, identify the addresses used by the EMS driver. Then set the adapter to
addresses that do not conflict.
NOTE: These conflicts can occur because the automatic configuration
program sets up only the hardware. It does not consider the operating system or
application requirements. If you run automatic configuration after changing
an address, the addresses you changed will be set back to their default values.
