IDE1 is also known as the primary channel and IDE2 as the secondary channel. Each channel supports two IDE devices that make a total of four devices. In order to work together, the two devices on each channel must be set differently to Master and Slave mode. Either one can be the hard disk or the CDROM. The setting as master or slave mode depends on the jumper on your IDE device, so please refer to your hard disk and CDROM manual accordingly.

This motherboard supports ATA33 modes. The IDE bus is 16-bit, which means every transfer is two bytes.

It is very popular that the Over Current Protection is implemented on ATX 3.3V/5V/12V switching power supply. However, the new generation CPU uses different voltages that has regulator to transfer 5V to CPU voltage (for example, 2.0V), and thus makes 5V over current protection useless. This motherboard is equipped with switching regulator onboard which supports CPU over-current protection; in conjunction with 3.3V/5V/12V power supply to provide the full line over-current protection.

Note: Although we have implemented protection circuit, try to prevent any human operating mistake. There is still certain risk that CPU, memory, HDD, and add-on cards installed on this motherboard may be damaged because of component failure, human operating error or other unknown reasons. AOpen cannot guarantee the protection circuit will always work

The power circuit of the CPU core voltage must be checked to ensure system stability for high speed CPUs (such as the new Pentium 4, or when overclocking). A typical CPU core voltage is 2.0V, so a good design should control voltage between 1.860V and

2.140V. That is, the transient must be below 280mV. Below is a timing diagram captured by a Digital Storage Scope which shows the voltage transient is only 143mv even when maximum 18A current is applied.

The layout of this motherboard implements AOpen’s unique design called “ Frequency Isolation Wall”. Separating each critical portion of motherboard into regions where each region operates in a same or similar frequency range to avoid cross talk and frequency interference between each region’s operations and condition. The trace length and route must be calculated carefully.

ATA/ 100 is a new IDE specification under developing. ATA /100 uses both rising edge and falling edge as ATA/66 but cl ock cycl e 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, t he s am e as ATA/66.

BBIIOOSS ((BBaassiicc IInnppuutt//OOuuttppuutt SSyysstteemm))

BIOS is a s et of assembly routine/prog ram that reside i n EPROM or Flash ROM. BIOS controls Input/output devices and other hardware devices of motherboard. In general, to provide hardware independent portability, operation system and drivers is required to access BIOS without directly access hardware devices.

BBuuss MMaasstteerr IIDDEE ((DDMMAA mmooddee))

The traditional PIO (Programmable I/O) IDE requires the CPU to involve in all the activities of the IDE access including waiting for the mechanical events. To reduce the workload of the CPU, the bus master IDE device transfers data from/to memory without interrupting CPU, and releases CPU to operate concurrently while data is transferring between memory and IDE device. You need the bus master IDE driver and the bus master IDE HDD t o support bus m aster IDE mode.

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. One of the solutions to connect digital television devices together at 200 Mbps. Serial Bus Management provides overall configuration control of the serial bus in the form of optimizing arbitration timing, guarantee of adequate electrical power for all devices on the bus, assignment of isochronous channel ID, and notification of errors. There are two type of IEEE 1394 data transfer: asynchronous and isochronous. Asynchronous transport is the traditional computer memory-mapped, load and store interface. Data requests are sent to a specific address and an acknowledgment is returned. In addition to an architecture that scales with silicon technology, IEEE 1394 features a unique isochronous data channel interface. Isochronous data channels provide guaranteed data transport at a pre-determined rate. This is especially important for time-critical multimedia data where just-in-time delivery eliminates the need for costly buffering.

PPaarriittyy BBiitt

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 tim e, if mem or y is r ea d wit h o dd n umb er of " 1", th e pari ty error is occurred and this is called single bit error detection.

For Socket 7 CPU, one burst data read requires four QWord (Quad-word, 4x16 = 64 bits). PBSRAM only needs one address decoding time and automatically sends the remaining QWords to CPU according to a predefined sequence. Normally, it is 3-1-1-1, total 6 clocks, which is faster than asynchronous SRAM. PBSRAM is often used on L2 (level 2) cache of Socket 7 CPU. Slot 1 and Socket 370 CPU do not need PBSRAM.

Based on FSB frequency, the DDR SDRAM has 200MHz and 266MHz two type of working frequency. Because of DDR SDRAM data bus is 64-bit, it provides data transfer bandwidth up to 200x64/8=1600MB/s, and 266x64/8=2100MB/s. Hence, the PC-1600 DDR SDRAM is working with 100MHz and PC-2100 DDR SDRAM is working with 133MHz FSB frequency.
