User manual AOPEN AX5T-OV

[. . . ] The AX5T and MP56 internal modem card implement special circuit (patent applied) to make sure the modem card work properly without any power. 1-1 Overview RTC Wake Up Timer The Wake Up Timer is more like an alarm, which wakes up and power on your system at a pre-defined time for specific application. It can be set to wake up everyday or on specific date within a month. High Efficient Synchronous Switching Regulator Most of the current switching designs are Asynchronous mode, which from the technical point of view, still consumes very high power as well as heat. AX5T implements high efficient synchronous switching design that the temperature of MOS FET is less than 36 degree C compared with 57 degree Schottky diode of Asynchronous design. [. . . ] 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 PV60/PT60), Sound Blaster compatible sound card and sound driver that supports APM (AOpen AW32 or MP56) for Suspend to Hard Drive to work properly. Of course, we recommend to use AOpen products for best compatibility. Go into BIOS setup, Power Management à Suspend Mode Option, select "Suspend to Drive". 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. Bootup your system into DOS command prompt. If you are Win'95 user, Please restart you Windows 95 under "Command Prompt" by pressing "F8" while system shows "Windows 95 Starting . . . ". Choose "Command Prompt Mode" from selection so that system will start in DOS command prompt. Use utility "ZVHDD" to create a partition in your hard disk drive. This partition is used to save your system status and memory image. Just type: C:>ZVHDD /c /partition /M:mmm Where mmm is the partition space you want to create. It is recommended to reserve enough space for your feature memory expansion. For example, if you plan to have 64MB main memory and 4MB VGA memory in the near future. If you are using FAT32 file system, please use this partition method. There is another method to create a hidden file in your hard disk drive for Suspend to Hard Drive to save your system status and memory image. C:>ZVHDD /c /file 1-5 Overview Please make sure that you have enough continuous HDD space for creating this hidden file. For example, if you have 16MB of system memory, you need at least 16MB (+ VGA memory size) of continuous HDD space. If ZVHDD failed to allocate the HDD space, you may run "DEFRAG" Utility or "Disk Defragmenter" which come with MS-DOS or Win'95 to free HDD space. After creating above partition or hidden file, please reboot your system. Push suspend switch (momentary mode) or use Win95 Suspend icon to force system goes into Suspend to Hard Drive mode and then turn system power off by power switch of your power supply. Next time you turn on your system, it will resume to your original work automatically. [. . . ] Internal modem card wake up signal is detected through cable from connector RING (on modem card) to WKUP (on mainboard). Tip: You can combine Suspend to Hard Drive, Modem Wake Up and the software Acephone for the best solution of answering machine or to send/receive fax. Note: If you use external modem, the power of external modem must be kept on to receive signal from telephone line. Internal modem card has no such limitation. 1-9 Overview 1. 4 System Voltage Monitoring AX5T implements a voltage monitoring system. [. . . ]
