- ---------------------------------------------------------------------------
-
- 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, DD260.SYS. 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 install 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 and D)S 6.0,
- which can be used to load device drivers into upper memory. Please refer
- to your DOS manuals for instructions on using DEVICEHIGH=. You will need
- 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. The version of the
- Microsoft CDROM Extensions program, MSCDEX.EXE, which is included on this
- distribution disk is NOT compatible with DOS 6.0 - do not install it. SETUP
- will automatically use the DOS 6.0 version if it finds that the DOS version
- is 6.0.
