Edisk.sys Ram Disk Device Driver - Everex EV-159 Owner's Manual And Reference Manual

5.2 EDISK.8YS RAM Disk Device Driver
The Everex utility EDISK.syS is a software device driver
that allows you to set aside part of the computer's base, ex-
panded or extended memory for a RAM disk. This RAM
disk is recognizable by DOS in the same manner as a hard
disk or floppy disk: you can create directories and sub-
directory paths on it, and can transfer and save your files
just like a standard disk. DOS will assign the next available
logical drive name to each RAM disk defined: for example,
your first RAM disk will be defined as Drive "C" if you
have no hard disks installed and as Drive "D" if you have
one installed.
The RAM disk has the following advantages:
A. Access times are very short because there are no
mechanical access procedures.
B. The RAM disk can be of any size. It can be made
larger or smaller, deleted and re-created, at will.
c.
You do not need additional hardware to implement a
RAM disk; this means you do not need to pay extra
money in order to implement a hard disk.
The RAM disk has the following disadvantages:
A. None of the data stored in a RAM disk is permanently
saved until you store the data on a real physical disk.
