- CD-ROM CONFIGURATION INFORMATION
- --------------------------------
-
- IBM does offer support for CDROM technology within the OS/2, and many
- other vendors are rapidly designed OS/2 device drivers for their CDROM
- peripherals. Unfortunately, there is a wide base of CDROM drives that
- do not yet have native device drivers for OS/2. Not to worry however;
- through the use of OS/2's Virtual DOS Machines, you can configure many
- CDROM drives to use in the OS/2 DOS environment.
-
-
-
- Ensure that you have the following:
- 1. A DOS 5.0 bootable diskette
- 2. MSCDEX.EXE v2.21, dated 2-4-92, size 25431 bytes
- if that is your CDROM's interface program.
- 3. CD-ROM device driver for your specific CD-ROM drive,
-
- NOTE: If you do not have the last two items please contact your
- CDROM vendor.
-
-
-
- STEP 1. Create a VMB from a DOS 5.0 bootable diskette, using the VMDISK command.
- If you need additional assistance please use the online command
- reference or call IBM support for the VMB procedure FAX.
-
- STEP 2. On this diskette place the following files as your setup requires:
- * COMMAND.COM (will be included when the DOS Boot diskette is made)
- * FSFILTER.SYS (from the \os2\mdos directory)
- * MSCDEX.EXE (v2.21 which does not require the use of the
- SETVER command)
- * The CDROM device driver from your vendor, for example UTEXCD.SYS
-
- STEP 3. Create a CONFIG.SYS file with the following:
- SHELL=A:\COMMAND.COM /P /E:1024
- DEVICE=A:\FSFILTER.SYS
- LASTDRIVE=Z
- DEVICE=A:\ [ CDROM-Device-Driver-Name-and-Parmeters ]
-
- STEP 4. Create an AUTOEXEC.BAT file with the following:
- SET COMSPEC=A:\COMMAND.COM
- PROMPT $P$G
- MSCDEX /D:Specific-Parameters-for-the-CDROM-Drive
- Most often this entry will look similar to MSCDEX /D:IBMCD001
- but may have additional parameters as specified in your
- CD-ROM vendor's documentation. Call your CD-ROM vendor for
- exact details. Most often the /D: parameter specifies the
- name of the device driver file from step 3, but not always.
-
- STEP 5. Now OPEN the SETTINGS for the VMB program object you created in
- STEP 1. From the settings NOTEBOOK, click the session tab, and then
- click the DOS_SETTINGS pushbutton to reveal the VDM's settings.
- Find the DOS_STARTUP_DRIVE entry, and the DOS_SHELL entry and
- have them point to the path and filename of the DOS VMB image file
- that you have created, for example C:\OS2\MDOS\DOS5.VMB
-
- STEP 6. Close the settings NOTEBOOK and Double-click mouse button 1 on the
- newly created program object. This should boot the image file and
- provide access to the CDROM drive. NOTE: you can only access
- the drive from this VMB session.
-
-
- The following is specific configuration examples for a SONY 535 drive:
-
- CONFIG.SYS [ SEE STEP 3 above ]
-
- DEVICE=C:\CDROM\SONY_CDU.SYS /D:MSCD210 /U:1 /B:340 /M:H /Q:* /T:*
-
- The /d: is the device name. Must be the same as in MSCDEX
- { /U:n } number of Drive daisy changed. Is optional
- {/B:XXX} Base address of CD HOSTADDRE default is 340.
- {/M:mode} Mode for data transfer. 'D' for DMA, 'P' for software transfer
- 'H' for high speed transfer (fast CPU).
- H is default for AT's and up, P is default for XT machines.
- {/T:drq} If using DMA, This specifies the DRQ channel number for the Host
- adapter will use. * means don't use.
- {/Q:irq} Specifies IRQ channel number to use. * means dont use.
-
-
- AUTOEXEC.BAT [ SEE STEP 4 above ]
- MSCDEX.EXE /D:MSCD210 /E /M:4 /L:S /V
-
- /D: Is the device name. Must match the onein the config.sys
- /M:X Species how many DOS buffers to use. The suggested minimum is 4-5
- /V says to display informnation about the CD
- /L:X SPECIFIES Which letter to give to the cd (like c:, D: ...)
- /E: says to use expanded memory.
