Expanded Memory Manager EMM.SYS
Version 4.01
(C) Copyright Everex Systems, Inc. 1986, 1987, 1988.
To boot up the system with the Expanded Memory Manager, insert the
following device driver entry in your CONFIG.SYS file:
DEVICE=[path]EMM.SYS [/C] [pppp] [port,page]* [/D] [/H(:nnn)]
Where
[] indicates an argument, do NOT type in the "[]" characters.
path is the directory where the EMM.SYS is located if you prefer
to store the EMM.SYS in a sub-directory of the boot disk.
(e.g. C:\EMM\EMM.SYS.....)
/C directs EMM.SYS to chain interrupt vector 67H. Chaining
permits software that uses vector 67H for other purpose
to coexist with Expanded Memory Manager.
pppp tells EMM.SYS where to start searching for a valid 64K page frame.
The page frame is the starting address of the EMS memory mapping
window. The pppp can be C400, C800, CC00, D000, DC00, or E000
(value in hexadecimal). C400 is the default value if pppp is not
specified.
port is the port address used to control the board.
port can be 208, 218, 258, 268, 2A8, 2B8, or 2E8
(value in hexadecimal).
page is the starting logical page on the board that supports
Expanded Memory. Page ranges from 00 to 7F (value in hexadecimal).
*If you have used the memory on this board to upgrade base memory
(e.g. from 512 to 640), your first available page will be 08.
/D tells EMM.SYS NOT to check the default page frame.
/H:nnn informs EMM.SYS of the maximum number of handles to support.
Default value for nnn is 64.
______________________________________________________________________________
EXAMPLES
Note that the device driver program file is located in the root
directory of the boot drive.
1. System configuration:
- an EV-158A at port 208 (hexadecimal)
The command line should be:
DEVICE=EMM.SYS 208,00
2. System configuration:

- an EV-171 at port 258 with starting EMS page 40 (hexadecimal)
- page frame to begin at segment address D000 (hexadecimal)
- interrupt vector 67 chaining enabled
The command line should be:
DEVICE=EMM.SYS /C D000 208,00 258,40
4. System configuration:
- an EV-158A at port 208 (hexadecimal)
- page frame to begin at segment address C800 (hexadecimal)

RAM Disk Device Driver EDISK.SYS
Version 2.03
(C) Copyright Everex Systems, Inc. 1986, 1987, 1988.
Version 2.03 of EDISK.SYS is different from the previous version is
that the maximum extended memory block transfer size is user
definable (compatible with IBM VDISK.SYS). This upgrade was done
to minimize loss of interrupts while extended memory input/output
occurs.
To boot up the system with the RAM Disk Driver, insert the following
device driver entry in your CONFIG.SYS file:
DEVICE=[path]EDISK.SYS [bbb] [sss] [ddd] [/E[:n]] [/X] [/L]
Where
[] indicates an optional item.
path is the directory where the EDISK.SYS is located if you prefer
to store the EDISK.SYS in a sub-directory of the boot disk.
(e.g. C:\EMM\EMM.SYS.....)
bbb is the total RAM disk capacity in Kbytes (1024 Kbytes = 1 Mbytes).
Ranges from 1 Kbyte to 15360 Kbytes
sss defines the logical sector size (number of bytes per sector).
Valid values are 128, 256, or 512(default) bytes per sector.
ddd sets the maximum number of entries allowed in root directory.
Ranges from 2 to 512. The default is 64 directory entries.
/E:n tells the EDISK.SYS to use EXTENDED memory to hold RAM disk.
The value n is the number of sectors to transfer in and out of
extended memory at any one time. This value is optional;
if included, n must be 1, 2, 3, 4, 5, 6, 7, or 8; if excluded,
the extended memory block transfer size defaults to 8.
/X tells the EDISK.SYS to use EXPANDED memory (EMS) to hold RAM disk.
/L tells the EDISK.SYS to skip adding a volume label to the RAM disk.
NOTE no '/E or /X' option directs EDISK.SYS to use the base memory.
An invalid argument (such as a sector size of 1024) will terminate
EDISK.SYS. Valid values that are out of range (such as a kbyte
buffer size that is larger than available memory) will be adjusted
appropriately.
_______________________________________________________________________________
EXAMPLES
1. Device=edisk.sys
This will create an all-default RAM disk: the edisk program will be stored
in the root directory, the buffer size is 128K, the sector size is 512
bytes, the maximum number of entries in the root directory is 64, and the
RAM disk will be located in base memory.
2. device=\everex\edisk.sys 256 /x
This will create an RAM disk with 256K of buffer size, by using
EXPANDED (EMS) memory. The EDISK.SYS device driver is stored in a
directory call \everex. The sector size and maximum directory entries
will be default values. (i.e. 512K and 64 respectively)
3. device=\everex\edisk.sys 256 /e
This will create an similar RAM disk as example 2. The only difference
is the RAM disk will be allocated with EXTENDED memory.
4. device=\everex\edisk.sys 1024 /e /l
This will create a RAM disk with no volume label.

Print Spooler Utility ESPOOL.EXE
Version 2.0
(C) Copyright Everex Systems, Inc. 1986, 1987
To allocate a print spooler, enter the following command line while
you are at a DOS prompt.
[path]ESPOOL [/B:bbb] [/E] [/X] [/P:n] [/S:n[,b,p,d,s,h]] [/R]
Where
[] indicates an optional item.
| indicates to choose one option among the choices.
/B:bbb informs ESPOOL.EXE to create a print spooler of a
particular Kbyte size. bbb ranges from 1 to 15360 Kbytes.
If the specified size is too large to fit in memory,
ESPOOL.EXE will automatically adjust the size. The default
is a 64 Kbytes if /b:BBB is omitted.
/E,/X informs ESPOOL to select which type of memory to use when
allocating the print spooler.
/E means using EXTENDED memory.
/X means using EXPANDED (EMS) memory.
Omitting /E or /X will cause the ESPOOL.EXE to allocate
a print spooler with base memory
/P:n informs ESPOOL to allocate the printer spooler on a parallel
printer port that specific by n where n can be 1 to 4.
/P:1 means spool on LPT1: (default)
/P:2 means spool on LPT2: .... etc.
/S:n informs ESPOOL to allocate the printer spooler on a serial
port that specify by n where n can be 1 to 4.
/S:1 means spools on COM1:
/S:2 means spools on COM2: .... etc.
b,p,d,s,h informs ESPOOL about the serial configurations.
b - is the Baud rate. It can be 110, 150, 300, 600,
1200, 2400, 4800, or 9600.
p - is the Parity. Valid values are as follows:
N for None, E for Even, and O for Odd.
d - is the number of data bits. Valid values are 7 or 8.
s - is the number of stop bits. Valid values are 1 or 2.
h - informs ESPOOL that the serial printer uses XON/XOFF
software handshaking protocol.
/R request ESPOOL to echo the spooler(s) current configuration
and status. This option is intended to be used alone.
When specified with other options, the other options will
be ignored.
______________________________________________________________________________
EXAMPLES
1. ESPOOL
This will create an all-default print spooler. 64 Kbytes of size using
base memory and spools on LPT1:.
2. ESPOOL /B:1024 /E /P:1
This will create a print spooler of size 1024 Kbytes using EXTENDED
memory and spools on LPT1:.
3. ESPOOL /B:1024 /X /P:2
This will create a print spooler of size 1024 Kbytes using EXPANDED (EMS)
memory and spools on LPT2:.
4. ESPOOL /B:1024 /X /P:1
ESPOOL /B:1024 /E /P:2
This will create two print spooler of equal size but using different
memory type. (Note: You can have more than one print spooler exists
at the same time.)
5. MODE LPT1:=COM1:
ESPOOL /B:2048 /E /S:1,9600,N,8,1,h
The first line reroute LPT1: to COM1:, this will make all printer
outputs go to COM1 rather than LPT1:
The second line will create a print spooler of size 2048 Kbytes using
EXTENDED memory and spools on serial port COM1: with the following
handshaking configurations:
BAUD rate is 9600
NO parity checking
8 data bits
1 stop bit
XON/XOFF protocol supported.
6. MODE LPT1:=COM1:
ESPOOL /b:2048 /E /S:1,1200,E,7,1,h
This will create a print spooler with same size like the above
example with differences in handshaking configurations.
BAUD rate is 1200
EVEN parity checking
7 data bits
1 stop bit
XON/XOFF protocol supported.
