Unlike ACPI, BIOS controls most APM power management functions. AOpen Suspend to Hard Drive is a good example of APM power management. ATA is the specification of diskette interface. In 80’s, many software and hardware manufacturers instituted the ATA specification together. -
Page 92: Ata/100
ATA/100 is a new IDE specification under developing. ATA/100 uses both rising edge and falling edge as ATA/66 but clock cycle time is reduced to 40ns. The data transfer rate is (1/40ns) x 2 bytes x 2 = 100MB/s. To use ATA/100, you need special 80-wire IDE cable, the same as ATA/66. -
Page 93: Cnr (Communication And Networking Riser)
The CNR specification provides the PC industry the opportunity to deliver a flexible and cost reduced method of implementing LAN, home networking, DSL, USB, wireless, audio and modem subsystems widely used in today's "connected PCs". The CNR specification is an open industry specification and is supported by OEMs, IHV card manufacturers, silicon supplier and Microsoft. -
Page 94: Dma (Direct Memory Access)
Channel for communications between the memory and surrounding devices. The ECC mode needs 8 ECC bits for 64-bit data. Each time memory is accessed; ECC bits are updated and checked by a special algorithm. The ECC algorithm has the ability to detect double-bit error and automatically correct single-bit error while parity mode can only detect single-bit error. -
Page 95: Ev6 Bus
Flash ROM can be re-programmed by electronic signals. It is easier for BIOS to upgrade by a flash utility, but it is also easier to be infected by virus. Because of increase of new functions, BIOS size is increased from 64KB to 256KB (2M bit). AOpen AX5T is the first board to implement 256KB (2Mbit) Flash ROM. -
Page 96: Fsb (Front Side Bus) Clock
FSB Clock means CPU external bus clock. CPU internal clock = CPU FSB Clock x CPU Clock Ratio See SMBus. IEEE 1394 is a low-cost digital interface originated by Apple Computer as a desktop LAN and developed by the IEEE 1394 working group. The IEEE 1394 can transport data at 100, 200 or 400 Mbps. -
Page 97: Parity Bit
The parity mode uses 1 parity bit for each byte, normally it is even parity mode, that is, each time the memory data is updated, parity bit will be adjusted to have even count "1" for each byte. When next time, if memory is read with odd number of "1", the parity error is occurred and this is called single bit error detection. -
Page 98: Pc-1600, Pc-2100 Or Pc-2700 Ddr Dram
Based on FSB frequency, the DDR DRAM has 200MHz, 266MHz and 333MHz three types of working frequency. Because DDR DRAM data bus is 64-bit, it provides data transfer bandwidth up to 200x64/8=1600MB/s, 266x64/8=2100MB/s and 333x64/8=2700MB/s in these current three DDR DRAM. Therefore, the PC-1600 DDR DRAM is working with 100MHz, PC-2100 DDR DRAM is working with 133MHz and PC-2700 with 166MHz FSB frequency. -

SDRAM comes in 64-bit 168-pin DIMM and operates at 3.3V. AOpen is the first company to support dual-SDRAM DIMMs onboard (AP5V), from Q1 1996 A memory space in Flash-ROM to simulate E PROM operation, AOpen motherboard uses Shadow E... -
Page 100: Simm (Single In Line Memory Module)
SIMM socket is only 72-pin, and is only single side. The golden finger signals on each side of PCB are identical. That is why it was called Single In Line. SIMM is made by FPM or DRAM and supports 32-bit data. SIMM had been phased out on current motherboard design. SMBus is also called I2C bus. -
Page 101: Ultra Dma
Ultra DMA (or, more accurately, Ultra DMA/33) is a protocol for transferring data between a hard disk drive through the computer’s data path (or bus) to the computer’s random access memory (RAM). The Ultra DMA/33 protocol transfers data in burst mode at a rate of 33.3MB/s, twice as fast as the previous Direct Access Memory (DMA) interface. -
Page 102: Vcm (Virtual Channel Memory)
NEC’s Virtual Channel Memory (VCM) is a new DRAM core architecture that dramatically improves the memory system’s ability to service multimedia requirements. VCM increases memory bus efficiency and performance of any DRAM technology by providing a set of fast static registers between the memory core and I/O pins. -
Page 103: Troubleshooting
If you encounter any trouble to boot you system, follow the procedures accordingly to resolve the problem. Start Turn off the power and unplug the AC power cable, then remove all of the add-on cards and cables, including VGA, IDE, FDD, COM1, COM2 and printer. Make sure if all jumper settings are correct. - Page 104 Continue Install the VGA card. Then connect your monitor and keyboard. Turn on the power and check if the power supply and CPU fan work properly. The problem is probably caused by power supply or motherboard failure. Next Please contact your reseller or local distributor for repairing.
- Page 105 Continue Perhaps your VGA card Check if there is display? or monitor is defective. Press <Ctrl> and <Alt> key at the same time, hold them and then press <Del> to reboot the system. It is very possible that your Check if the system keyboard is defective.
- Page 106 Continue During system rebooting, press <Del> to enter BIOS setup. Choose “Load Setup Default”. Turn off the system and re-connect IDE cable. The problem should be Check if the system can caused by the IDE cable reboot successfully? or HDD itself.
