Resolving configuration conflicts
The Configuration/Setup Utility program program
configures only the system hardware. It does not consider
the requirements of the operating system or the application
programs. For these reasons, memory-address
configuration conflicts might occur.
Resolving memory-address conflicts:
The
Configuration/Setup Utility program might change the
memory-address space used by some hardware options.
If this happens, the new address might conflict with
addresses defined for use through expanded memory
specification (EMS). (EMS is used only with DOS.)
If a memory conflict exists, one or more of the following
conditions might exist:
Ÿ
The system cannot load the operating system.
Ÿ
The system does not work.
Ÿ
An application program does not operate, or it returns
an error.
Ÿ
Screen messages indicate that a memory-address
conflict exists.
You can resolve memory-address conflicts by changing
either the software or hardware configuration setup.
Changing the software configuration
setup:
The best way to resolve memory-address
conflicts is to change the software configuration by
changing the addresses that the EMS device driver
defined. The SVGA video memory occupies 8 Kb (1 Kb
=
approximately 1000 bytes) of space in the hex C0000 to
C7FFF EMS memory area. EMS device drivers must use
addresses different from those assigned to video read-only
memory (ROM). You can use the Configuration/Setup
Utility program to view or change the current setting for
video ROM. For information about using the
Configuration/Setup utility programs, see
“Configuration/Setup utility usage” on page 22.
If the SVGA or EMM386 device driver is causing the
memory-address conflict, refer to the DOS documentation.
For conflicts caused by device drivers supplied with
application programs instead of those supplied with DOS,
refer to the documentation that comes with the device
drivers.
Changing the hardware configuration
setup:
An alternative way to resolve memory-address
conflicts is to change the address of the conflicting
hardware option.
