- 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.
-
-
- EQRAMDVR.SYS Options and Operation
-
- There is one option for EQRAMDVR.SYS. Typing a /n (where n is a
- number from 1 to 4) after DEVICE=EQRAMDVR.SYS sets the number of
- RAM disks that can be supported. In the instructions above, the
- /2 will allow the Equity I to support two RAM disks. If the /n
- option is omitted, EQRAMDVR.SYS sets up support for one RAM disk.
-
- When the system boots, EQRAMDVR.SYS will display a sign on
- mesage similar to this:
-
- RAM disk emulator support installed at drive(s) C:, D:
-
- There will from one to four drive letters shown, depending on the
- /n option. When you execute your RAM disk program, be sure to
- use the drive letter shown in the sign on message. For example,
- using Tecmar's MEMDISK program, you would type this command at
- the MS-DOS prompt:
-
- MEMDISK D: -BUF160
-
- This would set up a 160K RAM disk at drive D:.
-
- If you attempt to use one of the EQRAMDVR.SYS drives before
- running your RAM disk program, you will get one of the following
- error messages:
-
- Not ready error reading drive x
- Abort, Retry, Ignore?
-
- or
-
- Bad command error reading drive x
- Abort, Retry, Ignore?
-
- The x would actually be the letter of the drive you tried to
- access. Press A to abort, then run your RAM disk program.
