The table below contains a summary line for each of the major device types in a typical PC, showing the major resources that they typically use. It is a summary table containing the information from the summary tables for IRQ, DMA channel and I/O address usage. You can use this as a handy quick reference when looking to add a new device to your PC, or to assist in debugging a resource problem. Circle or highlight the devices you currently have and the resources they are using, and then you'll be able to see at a glance what resources are still available or possible ways that you could shuffle assignments to fit in a new peripheral.

The entries in bold represent the default resource usage in a typical PC; entries in regular text are optional resource allocations, or resources used by optional or non-standard devices:
