2•4

User’s Manual

2: Key Features & Components

Intel 845G/GL Chipsets

The mP4G and Mp4GL motherboards use variations of the Intel 845 Chipset, a multi-function chipset for higherend performance and mainstream systems. The mP4G uses the 845G chipset and the mP4GL uses the 845GL.

Both chipsets include a high performance onboard display graphics controller. The difference between the two is that the 845G chipset on the mP4G supports the use of an AGP display card installed in the AGP slot, while the 845GL chipset on the mP4GL does not. The 845GL chipset only allows the use of a DVI interface display card (for LCD flat-panel displays) or a TV-Out card in the onboard AGP slot.

The components of the chipset components include the following devices mounted on the board:

mP4G –

North Bridge: 82845G Memory Controller Hub (533MHz FSB)

South Bridge: 82801DB I/O Controller Hub (ICH4) mP4GL –

North Bridge: 82845GL Memory Controller Hub (400MHZ FSB)

South Bridge: 82801DB I/O Controller Hub (ICH4)

The chipset provides host bus, memory, AGP, and I/O interfaces.

Winbond Super I/O

Both motherboards also use the Winbond W83637HF Super I/O controller chip, which has the following functions:

Hardware monitor

Memory Stick/Secure Digital interface

Smart Card interface
