You can enable your device to be configured with resources allocated by the system BIOS. This ensures that only valid, available resources are allocated.
In the PnP Configuration Manager:
The device appears with a circular arrow icon.
If the BIOS is Plug and Play aware, it allocates resources to Plug and Play devices each time the system boots. When you enter the ISA PnP Configuration Manager after the system reboots, the device might or might not appear to be configured. This is because the SCO OpenServer PnP driver is not managing the device directly; instead, the system BIOS handles all configuration. What the BIOS reports to the manager is BIOS-dependent.
If you want to permanently assign resources to your Plug and Play device, you must specifically set them using the Edit button.
