Preventing Conflicts and Overlap ROM BIOS-Memory

As already explainedC000 and D000 are reserved for use by the ROM and RAM-board adaptersIf two adapters have the ROM and RAM addresses that overlap,then there is usually no air-board operating properlyEach board works if you change or disable one of thembut they do not work together.With many adapter boardyou can change the memory location to be used with a jumperswitch, or the driver software, which may be required so that two boards can co-exist within one systemThis type of conflict can cause problems fortrobleshooterYou should read the documentation for each adapter to find thememory address which is used by the adaptersand how to change the address so that there is coexistence with other adaptersMost of you can solve this problem byre-configure the board or by changing jumpersswitch settingsor software-driverparametersThis change makes the two boards can be side by side and separatedfrom one another.
In addition, you must make sure that the adapter board does not use port IRQaddressesDMA channelsor I / O the sameYou can easily avoid adapter boardmemory conflicts, IRQDMA channeland port I / O by making a chart or template to "cheat" the system configuration by writing to the template resource that has beenused by every adapter that is installedYou end up with an image resource systemand the relationship of each adapter.

If you are running a PnP operating system such as Windows 9x/Me or 2000/XPyoucan use Device Manager to view and print (optionalall equipment settingsI highlyrecommend that you use to print all of the settings in the your system before and after you make modifications, to know what has beenbenibah. This will rnembantu you to anticipate conflicts and ensure that you configure each adapter board correctly. The templates also becomes important when youmempeitimbangkan documentation to buy a new adapter. The new adapter must beconfigured to be able to use the resources that exist on your system.

If your system has the capability PnP, and PnP adapter you use, then the system canresolve the conflict between the adapter by changing the memory usage in all conflicts. Unfortunately, this routine is not smart enough and still requires human intervention - ie, the manual specification of addresses to get the most optimumlocation for the adapter memory.
