User manual AOPEN AP5T-OV

[. . . ] Chapter 1 Overview The AP5T 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. [. . . ] 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 support ACPI (normally, through BIOS modifications), it is still possible AP5T can not fully comply ACPI specification. 1-1 Overview There are also more features start to be implemented from AP5T revision 3. xx. Switching Power Regulator, Although Linear Regulator of AP5T revision 2 is good enough for AMD K6, AP5T revision 3. xx uses switching requlator to reserve the upgrade capability for new generation CPU. Over-current Protection, AP5T revision 3. xx implements 3. 3V (chipset, PBSRAM, SDRAM) 10A and 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. FCC DoC certificate The AP5T has also passed FCC DoC test, this means you can use any kind of housing with very low EMI radiation. 1-2 Overview 1. 1 Specifications Baby AT 220 mm x 280 mm Intel Pentium Processor P54C, PP/MT (P55C), AMD K5/K6, Cyrix 6x86 and IDT C6.
