You might say that /proc contains a "virtual filesystem." Take a look at
the fstab entry for /proc and /dev/pts.

Yah- I wouldn't touch /proc with a 50-foot pole for a million dollars.
Very dangerous stuff there. Although you're welcome to read it with
impunity: you probably can't damage anything just by looking at it.

I diagree. I presume you're making the analogy to thw Windows registry?
Windows' registry contains configuration info for applications (software
configuration). I don't think there's a single byte of info about hardware
configuration- which is what /proc is all about. /proc also contains info
on running processes. Again, nothing like this is in the Windows
registry.
If you're interested in IRQs and IO addresses, try `cat /proc/interrupts`
and `cat /proc/ioports`. This might be what you're looking for.
