Chapter 1: Introduction
1-4 Power Supply
As with all computer products, a stable power source is necessary
for proper and reliable operation. It is even more important for high
CPU clock rates like 75, 90, 100, 120, 133, 150, 166, 180, 200, 233
MHz and future Pentium processors for the SUPER P5MMA98/
P5MMS98/P5MMA2/P5MMS2 system board.
SUPER P5MMA98/P5MMS98/P5MMA2/P5MMS2 can accomodate ATX
or AT power supplies. Although most power supplies generally
meet the specifications required by the CPU, some power supplies
are not adequate. To obtain the highest system reliability, be cer-
tain that your power supply pr5 VDC with a voltage range
b4.95 VDC (minimum) and +5.25 VDC (maximum).
It is highly recommended that you use a high quality power supply.
Additionally, in areas where noisy power transmission is present,
you may choose to install a line filter to separate noise from the
computer. You can also install a power surge protector to help
avoid problems caused by power surges.
1-5 Chipset Overview
The Intel 82430 TX chipset consists of the TX System Controller
82439 TX (MTXC) and the PCI ISA IDE Xcelerator 82371 (PIIX 4).
The chipset forms a host-to-PCI bridge and provides the second
level cache control and a full function 64-bit data path to the main
memory. The MTXC integrates the cache and main memory DRAM
control functions and provides bus control to transfers between the
CPU, cache, main memory, and the PCI bus. It is highly integrated
by including the data path into the same BGA chip. Using the snoop
ahead feature, the MTXC allows PCI masters to achieve full PCI
bandwidth. For increased system performance, it integrates posted
write and read prefetch buffers. The 430 TX chipset integrates
many power management features that will enable the system to
save power whenever the system resources become idle.
