Overview
The AP5TC is a high-performance Pentium
-based system board that utilizes
the PCI/ISA architecture and
Baby AT
form factor. It integrates the Intel
82430TX
PCIset, a Super I/O controller, and a PCI mode 4 enhanced IDE
controller with bus master and
Ultra DMA/33
to enhance system performance.
It has
512KB
pipelined-burst second-level
cache onboard
and support four
single in-line memory module (SIMM) plus two Dual in-line memory module
(DIMM) that allow to
mix EDO and SDRAM
memory and expansion up to a
maximum of 256MB. For the memory and IDE performance, the Intel 430TX
chipset is currently the
fastest Pentium chipset
in the market.
In addition, AP5TC also implements many special features as following.
Switching Power Regulator
Although Linear Regulator is good enough for
AMD K6, AP5TC uses switching requlator to reserve the upgrade capability for
new generation CPU.
Over-current Protection
AP5TC implements CPU core voltage 15A over-
current protection to prevent any accident short circuit and prevent system
damage.
CPU Thermal Protection
When CPU temperature is higher than a predefined
value, the CPU speed will automatically slow down and there will be warning
from BIOS and also ADM (AOpen Desktop Manager, similar as Intel LDCM), if
ADM is installed.
Full-range CPU core voltage
This motherboard supports the CPU core
voltage from 1.3V to 3.5V, that can be applied to various CPU type in future.
Resetable Fuse
AP5TC implements resetable fuses to prevent any accidental
short circuit caused by keyboard or USB devices hot plug.
PCI Sound Card connector
The SB-LINK connector can be used to link
Creative-compatible PCI sound card. If you have a Creative PCI sound card
installed, it is necessary to link the card to this connector for compatibility issue
under DOS environment.
