Hardware compatibility is particularly important if you have an older
system or a system that you built yourself. Red Hat Linux 7.2 should be
compatible with most hardware in systems that were factory built
within the last two years. However, hardware specifications change
almost daily, so it is hard to guarantee that your hardware will be
100% compatible.
First, gather all the system hardware information you can; Chapter 2 and Chapter 4 have instructions
(including instructions for Windows users) which may assist you.
