User manual AOPEN P5TC-OV

[. . . ] 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 overcurrent protection to prevent any accident short circuit and prevent system damage. [. . . ] Default AT compatible keyboard, mini-DIN PS/2 keyboard connector is optional. AWARD Plug-and-Play Flash ROM BIOS Form Factor Board Size CPU System Memory Second-level Cache Chipset Expansion Slots Serial Port Parallel Port Floppy Interface IDE Interface USB Interface PS/2 Mouse Keyboard RTC and Battery BIOS 1-3 Overview Suspend to Hard Drive Switching Regulator Over-current Protection CPU Thermal Protection SB-LINK connector supported Supported by BIOS, save your work to hard disk and resume within a very short time. CPU core voltage 15A over-current protection to prevent any accident short circuit. The SB-LINK connector can be used to link Creative PCI sound card. 1-4 Overview 1. 2 Suspend to Hard Drive Suspend to Hard Drive saves your current work (system status, memory and screen image) into hard disk, and then the system can be totally power off. Next time, when power is on, you can resume your original work directly from hard disk within few second without go through the Win95 booting process and run your application again. If your memory is 16MB, normally, you need to reserve at least 16MB HDD space to save your memory image. Note that you have to use VESA compatible PCI VGA (AOpen PV70/PT70), Sound Blaster compatible sound card and sound driver that supports APM (AOpen AW35 or MP56) for Suspend to Hard Drive to work properly. Although Suspend to Hard Drive is so powerful, it is actually a little complicated to set up this function. To use Suspend to Hard Drive, please make sure you have read the following in detail. Go into BIOS setup, Power Management à Suspend Mode Option, select "Suspend to Disk". Go into BIOS setup, PNP/PCI Configuration à PnP OS Installed, select "No". This can give BIOS the capability to allocate system resources for Suspend to Hard Drive. If you are Win'95 user, Please restart your Windows 95 under "Command Prompt" by pressing "F8" while system shows "Windows 95 Starting . . . ". Choose "Safe Mode Command Prompt Only" from selection so that system will start in DOS command prompt. Option 1: Use /file switch (applied to FAT16 file system): Please use following command to create a hidden file in the root directory of your hard disk for Suspend to Hard Drive to save the system status and memory image. C:>AOZVHDD /c /file Please make sure that you have enough continuous HDD space for creating this hidden file. For example, if you have 32MB of system memory and 4MB of VGA memory, you need at least 36MB (32MB + 4MB) of continuous HDD space. If AOZVHDD failed to allocate the HDD space, you may run "DEFRAG" Utility or "Disk Defragmenter" which come with MSDOS or Win'95 to free HDD space. 1-5 Overview Option2: Use /partiton switch (applied to FAT16/FAT32 file system): To create a separate partiton for Suspend to Hard Drive, please make sure you have allocated a free partition. [. . . ] Disable the USB Legacy function. 1-7 Overview 1. 3 CPU Thermal Protection This motherboard implements special thermal protection circuit below the CPU. When 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) or Hardware Monitor utility software. If you do not need network monitor function, you may also use Hardware Monitor utility, which is a small utility for hardware monitoring. Both ADM and Hardware Monitor utility are available on the bundled CD and our web site (hhtp://www. aopen. com. tw). [. . . ]
