---------------------------------------------------------------------------
Section 1. If there will be only one CDROM drive on your system
If you want to use the factory settings (i.e. you have not changed the
jumpers on the CM260 host adapter), you may run Quick Setup, by pressing
F3. This will install the CDROM software on your startup disc and modify
your startup files to load the software when your system is restarted.
If you need to change the settings or the name of the directory where
Setup will install the software, run Full Setup, by pressing F4.
---------------------------------------------------------------------------
Section 2. If there will be more than one CDROM drive
Run Full Setup, by pressing F4, to install the CDROM software files, but
skip editing CONFIG.SYS and AUTOEXEC.BAT, the startup files.
In the CONFIG.SYS file, Setup allows for only one active statement loading
a device driver for the CM260 host adapter. Setup allows you to change the
options settings on that line, but not to add another. To access more than
one CM260 host adapter, you must set the jumpers on each adapter to a unique
port and a unique IRQ, and then you must edit the CONFIG.SYS file to add a
"DEVICE=" statement for each adapter. Use the /P and /I switch options to
assign each copy of the driver to a specific adapter, and use the /D option
to assign each a unique tag name. Setup does not detect any device driver
other than DD260.
In the AUTOEXEC.BAT file, Setup allows for only one /D:tag_name switch in
the statement which loads the Microsoft CDROM Extensions program, MSCDEX.EXE.
Setup allows you to change the tag name, but not to add another. To access
more than one CDROM drive thru MSCDEX, you must edit the AUTOEXEC.BAT file
to add a /D switch for each device driver you have loaded. Drive letters
will be assigned by tag names from left to right.
For example, to access two CM260 adapters and one generic adapter, in the
CONFIG.SYS file :
DEVICE=C:\CDROM\DD260.SYS /P:340 /I:3 /D:MSCD001
DEVICE=C:\GENERIC\GENERIC.SYS /D:MSCD002
DEVICE=C:\CDROM\DD260.SYS /P:330 /I:6 /D:MSCD003
and in the AUTOEXEC.BAT file :
C:\CDROM\MSCDEX /L:G /D:MSCD003 /D:MSCD001 /D:MSCD002
The drive attached to the CM260 host adapter set for port 340 and IRQ 3 is
drive H, the drive on the other CM260 is drive G, and the generic drive is
drive I.
---------------------------------------------------------------------------
Section 3. If you are connected to a network
You may use Setup to install the CDROM software files and to edit your
startup files. Before restarting your system, you must edit your
AUTOEXEC.BAT file to move the statement that loads the Microsoft CDROM
Extensions program, MSCDEX.EXE, so that it is after any statements that load
network software and before any that load an operating environment (e.g.
DOSSHELL or Microsoft Windows). The network software will not install
properly if MSCDEX is installed first.
It is recommended that your network administrator inspect the changes
Setup makes to your startup files.
---------------------------------------------------------------------------
Section 4. If you want to load the CDROM software into upper memory
The device driver for the CM260 host adapter, DD260.SYS, has been
successfully tested with the DEVICEHIGH= feature of DOS 5.0, which can be
used to load device drivers into upper memory. Please refer to your DOS
manuals for instructions on using DEVICEHIGH=. You will have to edit your
CONFIG.SYS file to make this change. The DD260.SYS driver has not been
tested with other, similar software.
The Microsoft CDROM Extensions program, MSCDEX.EXE, cannot be loaded
into upper memory. The /E switch asks MSCDEX to allocate expanded memory
for its buffers only.
---------------------------------------------------------------------------
Section 5. If you just want to update the CDROM software files
Run Full Setup, by pressing F4. After the files have been copied, you
can skip editing the startup files, CONFIG.SYS and AUTOEXEC.BAT, keeping
your current startup settings.
---------------------------------------------------------------------------
Section 6. If you want to verify the CM260 host adapter settings
The CM260 host adapter and the CDROM drive must be installed before
running this test.
Run Verify Setup, by pressing F5. This will try to access the CDROM
drive using the settings for port and IRQ from the DEVICE= statement that
was added to the CONFIG.SYS file. If you have not edited the CONFIG.SYS
file during this run of Setup, Verify Setup will use the factory settings.
If Verify Setup fails:
1) check that the settings match the jumpers on the host adapter,
2) check that no other expansion boards use those settings, and
3) check that all cables are properly installed.
---------------------------------------------------------------------------
Section 7. If you want to use host RAM for buffers (/M option)
Both MSCDEX and DD260 allow you to allocate space in host RAM, your
computer system's main memory, for buffers. In both cases, the number of
buffers is given by an option switch, /M. MSCDEX will keep directory
information in its buffers. DD260 uses the buffers to read ahead.
Allocating more buffers will usually improve performance, but at the cost
of increasing the memory used by these programs.
It is recommended that you accept the defaults offered. These settings
will give good performance on most systems for most applications.
---------------------------------------------------------------------------
Section 8. If you are using DOS 6.0.
DOS 6.0 contains a compatible copy of MSCDEX.EXE. That version of the
Microsoft CDROM Extensions program is included on this distribution disk
and is compatable with earlier versions of MS-DOS.
---------------------------------------------------------------------------
Section 9. Using the special functions flags
The flags parameter provides for special functions which may be required
due to the CDROM drive and host adapter environment or application disks.
Function 1: Protect against sound card software hangs.
The read-ahead function of the CDROM device driver can be interfered
with by similar background operation of some sound card software.
If the application hangs during operation with a sound card, try this
flag.
Function 2: Operate a 2x drive exclusively at 1x
Some application disks have been designed to operate at 1x
(single) speed and appear to run poorly or unnaturally
when operated at the 2x (double) speed. If this is the
case, try this flag.
Function 4: Operate with PCs with fast busses
Most PCs can operate at the standard ISA speed of 8 MHZ. The CM260
host adapter should be run only in a standard ISA bus running at
8 MHZ. If the bus cannot be slowed to 8 MHZ or if the bus fails to
meet ISA standards for signal timing, you may experience a high rate
of data errors. If this occurs on your PC, try this flag.
Multiple flags:
Any combination of the above special functions may be turned on by adding
the flag values. The following table defines the result of all possible
flag sum combinations:
/f:0 No special functions (default)
/f:1 Protect against sound card software hangs
/f:2 Operate a 2x drive exclusively at 1x
/f:3 Protect against sound card software hangs
Operate a 2x drive exclusively at 1x
/f:4 Operate with PCs with fast busses
/f:5 Protect against sound card software hangs
Operate with PCs with fast busses
/f:6 Operate a 2x drive exclusively at 1x
Operate with PCs with fast busses
/f:3 Protect against sound card software hangs
Operate a 2x drive exclusively at 1x
Operate with PCs with fast busses
