AOpen AP5T User Manual

Chapter 1
Overview
The AP5T is a high-performance Pentium -based system board that utilizes
the PCI/ISA architecture and Baby AT form factor.
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 256KB or 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.
Another feature that AP5T intends to implement is the new power
management features of Advanced Configuration Power Interface (ACPI).
The most attractive feature of ACPI for desktop user is probably OnNow, an
idea from Notebook. You don't have to go through the entire boot process, into
Win95, and back to your original work. Since ACPI specification is not fully
defined yet. AP5T implements Suspend to Hard Drive by BIOS, from user
point of view, it is the same as OnNow. Note that you have to use VESA
compatible VGA (AOpen S3 PCI PV70/PT70), Sound Blaster compatible
sound card (AOpen AW35/MP56), Rockwell compatible Modem (AOpen
F56/MP56) for Suspend to Hard Drive to work properly.
Note: ACPI is a specification of PC97, it is not
fully defined yet. Although AOpen will try the best
to
modifications), it is still possible AP5T can not fully
comply ACPI specification.
