75DRV3/75DRV3+
ATAPI (AT Attachment Packet Interface)
This is the exension of the EIDE (extended IDE) that enables the interface
to support CD-ROM players and tape drives.
BIOS (Basic Input/Output System)
BIOS is a set of assembly routine/program that resides in EPROM or
Flash ROM. BIOS controls Input/output devices and other hardware
devices of the mainboard. Generally, operation system and drivers will
access BIOS before accessing hardware devices so as to enhance the
portability of the hardware devices.
Bus Master IDE (DMA mode)
An IDE interface is an interface for mass storage devices, in which the
controller is integrated into the disk or CD-ROM itself. 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 to
support bus master IDE mode.
CAS (Column Address Strobe)
CAS is a technology of DRAM writes and reads. The number of clock
cycles of the CAS signals is depending on the DRAM timing.
CNR (Communication and Networking Riser)
CNR interface provides a cost reducing method of implementing LAN,
home networking, DSL, USB, wireless, audio and modem subsystems
through a CNR card and a CNR connector.
CODEC (Coder and Decoder)
Normally, CODEC means a circuit that can do digital to analog
conversion and vice versa. It is part of AC'97 sound/modem solution.
DDR (Double Data Rated) SDRAM
DDR SDRAM essentially doubles the memory speed of SDRAMs
without increasing the clock frequency.
