DOS PARTITION
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. A computer’s disk devices may
also have extended DOS partitions. Each DOS partition is
assigned a unique drive letter, such as C or D. A single disk
device can have multiple partitions. After you have installed EZ-
SCSI you can use the AFDISK utility program to partition disk
devices.
DOUBLE WORD PIO TRANSFERS
This is a type of data transfer done by 386 and newer micropro-
cessors. With the Adaptec AIC-6360 based host adapters (AHA-
1510A/1520A/1522A and PCM-3420), this can result in up to a
20% increase in performance over the AIC-6260 based host
adapters.
