You need to use command called lsdev. It gathers information about your computer’s installed hardware from the interrupts, ioports and dma files in the /proc directory, thus giving you a quick overview of which hardware uses what I/O addresses and what IRQ and DMA channels.
This command is very useful while troubleshooting various hardware conflict problems.
