Page 86: Amr (Audio/Modem Riser)
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 87: 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 88: 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 89: 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 90: 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 91: 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 92: 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 93: 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. -
