Processor

The LI7WM motherboard is designed to take a Intel 810E processor
running from 300/ 333/ 366/ 400/ 433/ 466/ 500/ 533/ 566/ 600 to
633MHz at 66MHz CPU bus speed or 550/ 600/ 650/ 700/ 750/ 800/
850/ 900/ 950MHz at 100MHz CPU bus speed or 600/ 666/ 733/ 800/
866/ 933 at 133MHz CPU bus speed with its Socket 370 processor
connector.

3.2 L2 Cache

The L2 cache is integrated in the Intel 810E 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 DMA Channels

There are seven DMA channels available on the motherboard. Only
DMA2 is used by the floppy controller. In the case that ECP mode on
the parallel port is utilized, DMA1 or DMA3 will be used.
3.4

BIOS

The BIOS on the LI7WM motherboard provides the standard BIOS
functions plus the following additional feature:
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.
3.5 Onboard Multi-I/O
Onboard AC97 Codec with external connectors for Line
out, Line in, Mic, and Game port.

3.6 I/O Port Address Map

Each peripheral device in the system is assigned a set of I/O port
addresses, which also becomes the identity of the device. There is a
total of 1K port address space available. The following table lists the
I/O port addresses used on the motherboard.
