9 Limitations
9.1 ISA 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
9.2 Windows 2000
Windows 2000 can only be installed, when in the BIOS setup ACPI is disable.
