9 Limitations

9.1ISA Bus

Memory accesses are not supported on the ISA bus. I/O accesses are only supported if they fall into one of the 4 generic decode ranges provided by the chipset. If a plugin ISA card is using registers in I/O space, this address range has to be enabled explicitely using the decode range and size setup items provided under the menu "Advanced" -> "Advanced Chipset Control" -> "ISA Options".

The following devices may also consume a generic decode range which can no longer be used for plugin cards.

"Advanced" -> "I/O device Configuration" -> "SIO Options"

"External SIO": SIO2 config space, if this range is released (item set to disabled), none of the devices in the external SIO will work

Serial Port C/D: consumes one range if either one or both COMs are enabled

External LPT: Consumes one range if enabled

"Advanced" -> "Hardware Monitor"

"Hardware Monitor": consumes one range if enabled, disable if you don't require HWM support.

Note:

the BIOS doesn't check the range and size values set in the ISA Options menu. Ensure that theses values do

 

not conflict with other legacy and PCI I/O resources. Resource conflicts may render the board inoperable.

 

If the number of generic decode ranges is exhausted, a conflict marker will be displayed

 

 

9.2Windows 2000

Windows 2000 can only be installed, when in the BIOS setup ACPI is disable.
