82374SB Datasheet
82374EB 82374SB
This document describes both the 82374EB and 82374SB components Unshaded areas describe the
82374EB Shaded areas like this one describe the 82374SB operations that differ from the 82374EB
The 82374EB SB EISA System Component (ESC) provides all the EISA system compatible functions The
ESC with the PCEB provide all the functions to implement an EISA-to-PCI bridge and EISA I O subsystem
The ESC integrates the common I O functions found in today’s EISA-based PC systems The ESC incorp-
orates the logic for an EISA (master and slave) interface EISA bus controller enhanced seven channel DMA
controller with scatter-gather support EISA arbitration 14 channel interrupt controller Advanced Programma-
ble Interrupt Controller (APIC) five programmable timer counters and non-maskable-interrupt (NMI) control
logic The ESC also integrates support logic to decode 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
The 82374SB also contains support for SMM power management
