I'm sure there are more devices than this, and I know the PCI space is in a different place completely. |

You're after the "Ralf Brown's Int List" or RBIL. It has most BIOS INT's, memory maps, PCI device cfg lists, etc.
It should have everything you're after. Grab it here: http://www.cs.cmu.edu/~ralf/files.html |

There's also an online/html version, which might be more handy: http://www.ctyme.com/rbrown.htm

The first 512 addresses are reserved for system devices (eg. system speaker that makes beeeeeps, int. controllers, etcetera)
BTW, is this any different for 64-bit processors? Ralf Brown's Interrupt List (as I found it) only specifies interrupts for up to 80586 (Pentium) |
