User manual AOPEN AX5T-OV

[. . . ] 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. 3V Over Current Protection Circuit The Over Current Protection was very popular implemented on the Baby AT or ATX +5V/+12V switching power supply. But unfortunately, the new generation CPU and chipset use 3. 3V or 2. 8V voltage that have regulator to transfer 5V to 3. 3V/2. 8V, and make 5V over current protection useless. [. . . ] 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 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. 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. 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. 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. 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. Tip: Following VGA card have been tested & recognized as VESA compatible VGA device.

AOpen AW32 AOpen MP56 Creative SB 16 Value PnP Creative SB AWE32 PnP ESS 1868 PnP If your sound card can not work after resume from Suspend to Hard Drive, check your sound card vendor see if there is driver to support APM, and install it again. [. . . ] You are now ready to use Modem Ring Tip: External modem wake up signal is detected through COM1 or COM2. 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. [. . . ]
