Win95b won't see Mitsumi CDROM in a Presario 7170

[OldPCKen]

Hi,

A Compaq Presario 7170, that I am setting up for my father-in-law, is driving me nuts! The Windows 95b system on a hard drive transfered from another PC most of the time will not see the Mitsumi CDROM drive model CRMC-FX410A1, a 4x speed. When it does see it, I can't read from the drive. In DOS mode with DOS drivers, The CDROM works fine.

What is confusing to me, is that the HDD, that I pulled out of the 7170 has Windows 95 OEM and the CDROM is seen and works fine in windows. It also has no help from config.sys or autoexec.bat.

This Compaq has a Phoenix BIOS and I updated the BIOS last week with the most current version.
I have used atapi.sys, tried mtmcdai.sys, device drivers mtmcdai.vxd and mtmcdai.386. I downloaded several files that are supposed to go with that CDROM to no avail.

I also find that my hard drive does not show up in Device Manager. The IDE controllers show as "Standard IDE/ESDI controller". Do I need updated IDE drivers? Please help! Thank you.

I am not using that drive myself, but I do have an old install disk for "Mitsumi atapi(ide bus) cd-rom drive device Driver & setup utilities version 1.55"
Here is the readme from the disk:
=========================================
| SOFTWARE INSTALLATION PROCEDURES |
=========================================

To install your CD-ROM drive for use with MS-DOS, you need:

* An IBM personal computer or compatible with 80386 or later
processor chip and a minimum of 640K of conventional memory.
* A CD-ROM drive (included).
* CD-ROM installation disk (included).
* MS-DOS Version 3.1 or later.
* Microsoft MS-DOS CD-ROM Extensions(MSCDEX.EXE).

Note: Microsoft MS-DOS CD-ROM Extensions(MSCDEX.EXE) enables the
computer to access the CD-ROM drive. MSCDEX.EXE must exist
in your system in advance.

------------------------------------------
| WHAT'S ON THE INSTALLATION DISK? |
------------------------------------------

The installation disk contains all the software needed to install
and operate the CD-ROM. A list of the files and a brief
description of each follows:

MTMCDAI.SYS CD-ROM device driver.
MTMCDAI.386 Windows virtual device driver.
SETUPD.EXE CD-ROM installation program which tells the CD-ROM
driver how you want it organized.
READMEA.ENG Text file is written by English. (This text file.)
READMEA.GER Text file is written by German.
READMEA.FRE Text file is written by French.
READMEA.SPA Text file is written by Spanish.
READMEA.ITA Text file is written by Italian.
READMEA.JPN Text file is written by Japanese.

----------------------------------------------
| CD-ROM DEVICE DRIVER INSTALLATION |
----------------------------------------------

Certain software programs must be loaded in order to access a CD-
ROM disc in your CD-ROM drive as if it were an MS-DOS formatted
disk. The CD-ROM software files must be properly installed in your
computer before the CD-ROM drive can read a CD-ROM disc.

The procedure for installation is as follow:

1. Insert the supplied installation disk into drive A (or B).

2. Type A: (or B and press ENTER to select drive A (or B).

3. At the DOS prompt A:\ (or B:\), type SETUPD and press ENTER.
(Run the program SETUPD.EXE on the disk.)

4. Follow the instructions on the screen.

5. Reboot your system when it completes successfully.

--------------------------------
| DEVICE DRIVER PARAMETERS |
--------------------------------

The MTMCDAI.SYS file is device driver that can be installed in the
directory of your choice. The CONFIG.SYS file specifies this file,
thereby allowing your computer to identify and operate the CD-ROM
drive. This device driver can support up to 8 drives.

Most computers will function adequately with most of the default
settings for this file. However, there are some parameters that
can be changed, if necessary. This section explains the function
of each parameter. Use a text editor, such as MS-DOS "EDLIN", or
"EDIT" to modify the appropriate line in your CONFIG.SYS file.

For the MTMCDAI.SYS device driver, the line in CONFIG.SYS is in
the following format.

DEVICE=[drive:][path]MTMCDAI.SYS
/D:device-name [/P:xxx,yy] [/A:n] [/U:n] [/L:xx]

Note: The actual device driver entry is not truncated and should
be placed entirely on one line in the CONFIG.SYS file.

[drive:][path]MTMCDAI.SYS
Specifies the location (drive and directory) and name of the
device driver file.

/D:device-name
Specifies the device name of the CD-ROM drive (8 characters
maximum). This must be identical to the device name specified
in the MSCDEX.EXE parameters. For example:

DEVICE=C:\MTM\MTMCDAI.SYS /D:MTMIDE01

[/P:xxx,yy]
Specifies the IDE port that is connected to the drive, and the
interrupt request.

'xxx' should be the base address of IDE port.
xxx = 1f0 : Primary(Channel 1)
170 : Secondary(Channel 2)
1e8 : Channel 3
168 : Channel 4
'yy' should be the interrupt channel.
yy = 14 : Primary(Channel 1)
15 or 10 : Secondary(Channel 2)
12 or 11 : Channel 3
10 or 9 : Channel 4

Only when the CD-ROM drives are connected to the primary port
using interrupt channel 14 and/or the secondary port using
interrupt channel 15 is it unnecessary to specify a /P
parameter.

For example, when eight drives has been connected, the syntax
in the CONFIG.SYS file should be as follows:

DEVICE=C:\MTM\MTMCDAI.SYS
/D:MTMIDE01 /P:1f0,14 /P:170,15 /P:1e8,12 /P:168,10

Note: The actual device driver entry is not truncated and
should be placed entirely on one line in the CONFIG.SYS
file.

[/A:n]
Specifies the audio play mode. For a stereo CD, /A:0 or /A:1
is acceptable. For a monaural CD (left or right channel only),
/A:1 will play the monaural audio signal from both the right
and the left channels. Default is n=0.

[/U:n]
Specifies the door lock or unlock. /U:0 is 'unlock'. /U:1 is
'lock'. Default is n=0.

[/L:xx]
Specifies the message language. Applicable language is as
follows:

'xx' = US : English (This is default.)
GR : German
FR : French
SP : Spanish
IT : Italian
JP : Japanese

If you want English, you do not have to specify. If you want
the other language, the syntax in the CONFIG.SYS file should
be as follows:

DEVICE=C:\MTM\MTMCDAI.SYS /D:MTMIDE01 /L:JP


-------------------------------------------
| REGARDING MTMCDAI.386 |
-------------------------------------------

If you use Windows with 32-bit Disk Access enabled, you should use
MTMCDAI.386 (only same IDE port with hard disk).
Setup program will help you install automatically.
If you want to install manually, the following line should be
added in [386enh] section of SYSTEM.INI file.

DEVICE=[drive:][path]MTMCDAI.386


Known Problem: The this driver does not work correctly under the
following configuration.
* Windows for Workgroups 3.11
32-bit Disk Access enable
32-bit File Access enable
* Compressed hard disk by software (DBLSPACE,STACKER...)

You should disable either 32-bit Disk Access or
32-bit File Access.


-------------------------------------------
| REGARDING SMARTDRV |
-------------------------------------------

SMARTDRV attached to MS-DOS 6.2 (PC-DOS 6.3) or later is supposed
to CD-ROM caching. If CD-ROM caching is enabled, it is possible
that CD-ROM does not work properly.(such as Photo CD)
In this case, you should add the following /U switch to disable
CD-ROM caching.

SMARTDRV.EXE /U

Maybe this will help. The disk contents are only 346kb
I could probably zip it up and mail it to you if you need it....

That HD contains info on all of the hardware that's in the system from which it was removed, and it's probably getting confused when trying to recognize the hardware in the Presario 7170.
You may have to reformat the drive, and reinstall Windows in order for things to work properly.

Also, if the Presario 7170 was made prior to Jan., 1999, and you want to use a Compaq Quick Restore CD to reinstall everything, then you have to write what's called a BOM ID to the HD. This number allows the Quick Restore CD to recognize the model number of the computer.

Thanks guys, I have used that very setup from the readme you showed me. I had thought there was no system partition on the HDD I took out of the 7170. I will have to put that hard drive back in to be sure. If it does, then I may upgrade that HDD and use it instead.
