Chapter 3 Hardware Description
LI6BM User’s Manual 9
3.1 Processor
The LI6BM motherboard is designed to take a Pentium II processor
running 233MHz/266MHz/300/333MHz at 66MHz CPU bus speed or
300/350/400/450/500MHz at 100MHz CPU bus speed with its Slot 1
processor connector.
3.2 L2 Cache
The L2 cache is integrated in the Pentium II processor. The private L2
cache bus is not connected to package pins; rather its signals are routed
between the two cavities using standard package techniques.
3.3 BIOS
The BIOS on the LI6BM motherboard provides the standard BIOS
functions plus the following additional features:
1. ISA Plug and Play (PnP) Extension
Unlike PCI cards that are Plug and Play, ISA cards require setting
jumpers to resolve hardware conflicts. To make a computer system
PnP, an ISA PnP standard is established and supported by new
operating systems, such as Windows 95. Under Windows 95, the
motherboard BIOS must have an ISA PnP extension to support new
ISA PnP cards.
2. Power Management
The power management feature provides power savings by slowing
down the CPU clock, turning off the monitor screen and stopping the
HDD spindle motor. The BIOS fully conforms to ACPI (Advanced
Configuration and Power Interface) specification.
