Standard hardware circuitry reserves only 1,024 byte of I/O addressing space from I/O $000 to $3FF for peripherals. All standard PC I/O peripherals, such as serial and parallel ports, hard and floppy drive controllers, video system, real-time clock, system timers and interrupt controllers are addressed in this region of I/O space. The BIOS initializes and configures all these registers properly; adjusting these I/O ports directly is not normally necessary. The assigned and user-available I/O addresses are summarized in the I/O Address Map, Table 2-2.DMA Controller 1 (Intel 8237A Compatible) $010 - $01F 16 Reserved $020 - $021 2 Master Interrupt Controller (Intel 8259A Compatible) $022 - $03F 30 Reserved $040 - $043 4 Programmable Timer (Intel 8254 Compatible)
