System Board

The M19A is a dual-processor system board built on an ATX
baseboard utilizing two Intel Pentium
II processors running at
333/66, 350/100, 400/100, or 450/100 MHz. It is integrated with the
Intel 440BX system controller, which consists of the PCI/AGP
controller and the PCI/ISA IDE accelerator (PIIX4).
The PCI/AGP controller host bus interface supports a Pentium II
processor with 66 or 100 MHz bus frequency. It also provides a 72-bit
DRAM that supports synchronous DRAM (SDRAM) DIMMs. The
PCI/AGP controller introduces a new technology, which is the
Accelerated Graphics Port (AGP) interface. Supporting up to 133 MHz
data transfer rate, the AGP interface boosts graphics performance.
The PIIX4 is a multifunctional PCI device controller implementing
system functions including PCI IDE, universal serial bus (USB)
host/hub, and enhanced power management. It also supports Ultra
DMA/33 synchronous DMA-compatible devices.
The four DIMM sockets on board allow memory upgrade to a
maximum of 512 MB and supports 72-bit DRAM using synchronous
