Old IBM PC has PIC (peripheral interrupt controller) - does the 16 IRQ
lines and attaches them to the CPU
Modern PC also as APIC (advanced peripheral interrupt controller) which
is in two parts - locsl apic is on the CPU, and talks over a link to one
or more io-apics that attach to the devices on the bus
"noapic" says to run the box like an old IBM PC
