WHY AND HOW TO USE EQRAMDVR.SYS

Many RAM disk programs supplied with expansion boards do not

work with an Equity I with dual floppy disks.

The Equity I

supports only two floppy disk drives, and these programs

expect the operating system to treat it as a floppy disk.

RAM disk utilities that are in device driver form (must be

specified in CONFIG.SYS) should have no problems.

Any RAM disk

utility that is executed from the system prompt will have problems

on a dual floppy Equity.

These are the programs EQRAMDVR.SYS

was designed to support.

The device driver EQRAMDVR.SYS provides

the support needed for these utilities by creating an 'empty' disk

drive that a RAM disk program can use when it is executed.

HOW TO USE EQRAMDVR.SYS

Since EQRAMDVR.SYS is a device driver,

it must be specified in

the CONFIG.SYS file on your boot disk.

See pages 3-1 to 3-4 in

"MS-DOS for the Equity I" for a description of the CONFIG.SYS

file. The boot disk can either be a floppy disk or a hard disk.

The file EQRAMDVR.SYS must also be copied to your boot disk.

In the following instructions,

[ENTER] means press the ENTER key,

and [F6] means press the F6 key.

1. Boot your system with your working copy of MS-DOS.

If you have a hard disk that is set to autoboot, boot

from the hard disk.

2. When the MS-DOS prompt appears, place the disk with

EQRAMDVR.SYS in drive B: (A: for hard disk systems).

For a floppy disk system,

type:COPY B:EQRAMDVR.SYS [ENTER]

For a hard disk system, type:

COPY A:EQRAMDVR.SYS [ENTER]

3. Check if CONFIG.SYS already exists on your boot disk by

typing: DIR CONFIG.SYS [ENTER]

If the message "File not found" appears, follow step 4a,

otherwise follow 4b.

4a.

Type:

COPY CON: CONFIG.SYS [ENTER]

DEVICE=EQRAMDVR.SYS /2 [ENTER]

[F6] [ENTER]

4b. Type: COPY CONFIG.SYS + CON: CONFIG.SYS [ENTER]

DEVICE=EQRAMDVR.SYS /2 [ENTER]

[F6] [ENTER]

Note:

The /2 above is optional.

It will be explained in the

following section.

5. Reset the system,

and your Equity I is now ready to use

a RAM disk program.
