208-Pin QFP Package

The 82378ZB System I/O (SIO) and 82379AB System I/O APIC (SIO.A) components are PCI-to-ISA Bus Bridge

devices. These devices integrate many of the common I/O functions found in today's ISA-based PC systems¾ a

seven channel DMA controller, two 82C59 interrupt controllers, an 8254 timer/counter, a BIOS timer, Intel SMM

power management support, and logic for NMI generation. In addition, the SIO and SIO.A each support a total of

six PCI Masters, and four PCI Interrupts. Decode is provided for peripheral devices such as the flash BIOS, real

time clock, keyboard/mouse controller, floppy controller, two serial ports, one parallel port, and IDE hard disk

drive.

For both the SIO and SIO.A, each DMA channel supports compatibility transfers. The SIO also supports types

A, B, and F transfers and scatter/gather. In addtion to the standard ISA-compatible interrupt controller that is in

both the SIO and SIO.A, the SIO.A contains an Advance Programmable Interrupt Controller (IO APIC) for use in

multi-processing systems.

This document describes both the 82378ZB (SIO) and 82379AB (SIO.A) components. Unshaded areas describe

the 82378ZB. Shaded areas, like this one, describe differences between the 82379AB and 82378ZB.

any patent or copyright, for sale and use of Intel products except as provided in Intel’s Terms and Conditions of Sale for such products.
