Using TD-220 System Resources

Available system resources are assigned to PCI devices before they are assigned to ISA
devices. To install more ISA devices than you have open IRQs, you must disable one unused
system port for each excess ISA device, unless the device does not require an IRQ.
To disable an unused system port:
1. Restart the system and start the BIOS Setup program.
2. On the Advanced/Peripheral Configuration screen, select the port you want to disable
(Serial Port 1 Address, Serial Port 2 Address, or Parallel Port Address).
3. Change the value of the setting to Disabled.
4. Save the changes and exit from the BIOS Setup program.
The following expansion cards require specific system resource settings, as noted (all are
ISA devices except for the Ensoniq PCI Sound Card):
