40 PCM-3420 User's Manual A Adaptec EZ-SCSI A user-friendly software program that automatically installs SCSI devices such as fixed disks and CD-ROM drives on a PC. Adaptec EZ-SCSI copies the required software programs to the PC’ s fixed disk and edits the configuration files so the host adapter can access the devices.
Appendix C Glossary of Terms 41 TERMPWR I n O ut //// SCSI signal GND /// SCSI signal G N D /// SCSI signal etc. Assuming that the TERMPWR voltage doesn’t drop below the desired termination voltage (plus the regulator ’ s minimum drop), the SCSI signals will always be terminated to the correct voltage level.
42 PCM-3420 User's Manual ASPI Advanced SCSI programming Interface. A standard SCSI soft- ware interface that acts as a liaison between host adapters and SCSI device drivers. ASPI enables host adapters and device drivers to share a single SCSI hardware interface.
Appendix C Glossary of Terms 43 B BIOS An acronym for Basic Input/Output System. This is usually an EPROM with computer program instructions in it. A motherboard BIOS (usually by companies such as Phoenix, A ward, and AMI) controls the basic functions of the computer (such as controlling the keyboard, monitor , etc.
44 PCM-3420 User's Manual C D DEVICE DRIVER A software program that enables a PC to communicate with peripheral devices such as fixed disk drives and CD-ROM drives. Each kind of device requires a different driver . Device driver programs are stored on a PC’ s fixed disk and are loaded into memory at boot time.
Appendix C Glossary of Terms 45 DOS P ARTITION A section of a disk storage device, created by the DOS FDISK program, in which data and/or software programs are stored. Computers have a primary DOS partition that contains the special files needed to boot the computer .
46 PCM-3420 User's Manual F F AST SCSI Provides for performance and compatibility enhancements to SCSI-1 by increasing the maximum synchronous data transfer rate on the SCSI bus from 5 MBytes/sec to 10 MBytes/sec. There are 2 handshaking modes on the SCSI bus, used for transferring data: ASYNCHRONOUS and SYNCHRONOUS.
Appendix C Glossary of Terms 47 FULL SCSI A SCSI solution that includes BIOS and support software to provide boot capability for hard disk drives, support for drives larger than 1 B, and full compatibility with removable media products (hard drives, optical drives, tape drives, and Floptical drives).
48 PCM-3420 User's Manual I I/O Refers to an operations, program, or device whose purpose is to enter data into or to extract data from a computer . IRQ Interrupt Request Channel. The IRQ of a host adapter can be changed to several different settings by changing jumpers and/or switch settings on the adapter board.
Appendix C Glossary of Terms 49 L M N Narrow SCSI device (as opposed to Wide SCSI device) This is the term attributed to today’ s 8 bit standard SCSI devices. This term is necessary to distinguish today’ s 8-bit SCSI devices to 16-bit W ide SCSI devices.
50 PCM-3420 User's Manual PORT I/O ADDRESS A window through which software programs communicate commands to an installed host adapter board. The commands are communicated 8 bits at a time. PROGRAMMED INPUT/OUTPUT A method of data transfer in which the host microprocessor transfers data to and from memory via the computer ’ s I/O ports.
Appendix C Glossary of Terms 51 S SCSI (Small Computer Systems Interface) A PC bus interface standard that defines standard physical and electrical connections for devices.
52 PCM-3420 User's Manual 1) W e have measured propagation delays from various cables and found an average of 1.7 nanoseconds per foot, which is roughly 5.25 ns per meter . 2) The turn-around time is the amount of time the SCSI chip takes to change an output in response to an input.
Appendix C Glossary of Terms 53 TERMINA TION A physical requirement of the SCSI bus. The first and last devices on the SCSI bus must have terminating resistors installed, and the devices in the middle of the bus must have terminating resistors removed.
54 PCM-3420 User's Manual SCSI, this can result of SCSI bus data transfer rates of 20 MBytes/ sec (with a 16-bit bus) or 40 MBytes/sec (with a 32-bit bus). SCSI may now transfer data at bus widths of 16 and 32 bits. Commands, status, messages and arbitration are still 8 bits, and the B-Cable has 68 pins for data bits.
