When the PC boots up, the BIOS sets up an interrupt vector
table at 0000:0000 with int 0x16 pointing into the BIOS keyboard
driver. Linux uses this same vector table to access BIOS disk
routines that are used for booting the system. Linux then sets up
its own interrupt vector table and switches into protected mode.
None of the original BIOS interrupts are then available, nor
are they needed. There are several ways to read a single character
at a time. One of the easier ways is provided by the curses
library. Get on Amazon and look at the programming books
by Matthew & Stones, and maybe even by J. Dennon.
