Uninstaling old CD-ROM Driver

Comment:

Hello All,

A few weeks ago I purchased a Toshiba 220CS Notebook from a car boot sale for the princely sum of £8!

It runs well but I have a problem with an old (16bit) CD - ROM driver in the Autoexec.bat file that loads before Windows.

I do not have this external CD attached (or n my possesion) but I would like to uninstall the driver as I have another External CD that I would like to use.

Additionaly this issue is slowing the time taken to boot up fully whilst Dos / Windows looks for the hardware which is no longer attached.

In the first instance I examined "Device Manager" to see if the device was (a) Detected & (b) marked with an exclaimation mark.

It was not deteced.

I then turned my attention to MSCONFIG and unchecked the appropriate line in the Autoexec.bat file - which has the effect of "remarking" (rem) it in the Dos autoexec.bat on boot up.

However this still delays the boot up speed and obviously is not as effective as unistalling the device driver totally.

I have also tried editing the entry directly(via Notepad). All that happened was that the device created a new file called Autoexec.tsh

I was wondering if anyone could advise me of a method wherby I can uninstall this driver (and it's associated files) properly?

Whilst in many respects this may transpire to be something of a DOS issue I have posted here as the notebook is primarily running Windows 98SE as it's operating system.

Many thanks,

Trevor

Did you look in Control Panel > Add/Remove?

Did you try booting into Safe Mode & running thru the list of entries in Device Manager? Removing duplicates or devices that are no longer present?

Do you actually *need* autoexec.bat or config.sys?

Yes - I did check the Add / Remove feature via control panel.

I have also tried Safe Mode (and even the DOS prompt)

I can see no reason I do need autoexec.bat but I was unaware that it was possible to safely delete this.

Thanks for your help.

You can remove both autoexec.bat and config.sys if you do not need to load any dos based real-mode drivers (in this case the external cdrom). You could delete the files, or (since I do use some games and older progs on 98SE) simly change the attribute of the original autoexec.bat file from read only and then edit out the troublesome lines, then save the edits. (Right click autoexec.bat>Properties and then uncheck read-only and click ok or apply.)

Thank you HTH.

I have already edited out what I belived to be the appriopriate line (the only one there).

Initially I did this via MSCONFIG but then I went to a (true) DOS prompt and verified the edit within MS - DOS Editor.

I am at a loss as to what to do regarding this problem.

I would also state that during the boot process a while after the Windows 98 screen has first appeared the process automatically returns to the prompt - C:\> then appears four times (accompanied by two beeps - Which is not the P.O.ST - That has already occured much earlier).

After that the system hangs for about 15 seconds and then it continues the boot process normally.

Obviously there is some rogue line of code somehwere during the boot process - bit how do I find exactly where !

At least with Linux you can see exactly what is happening !

Thanks anyway,
Trevor

OK, right click on AUTOEXEC.BAT, select copy, then paste right back in the C:\ directory...it should now be named "copy of AUTOEXEC.BAT". Rename it AUTOEXEC.TREV...this is now your backup. If you have any other AUTOEXEC.xxx files, delete ALL of them but do NOT empty the recycle bin (yet).

Now right click on the actual AUTOEXEC.BAT file & click EDIT...remove ALL lines contained in the file & save.

Move on to the CONFIG.SYS file. 1st make a backup copy as above & name it CONFIG.TREV...delete ALL other CONFIG.xxx files you have. Open the actual CONFIG.SYS file using notepad, remove ALL lines contained in the file & save.

Now reboot. If that above doesn't help, you can always restore the the files again by renaming the .TREV backup files that you just created

There was only one line in the original Autoexec.bat

First I tried "remarking" (rem) this line out to make it be ignored by the O/S.

Then I edited the line completely

There was still no change.

I did create a back up so I could restore from this if required.

If the Autoexec.bat file is completely empty I cannot see how it is causing a problem although I accept that it is at least in part contributing to this issue.

I have examined this system closely to verify that there is not a hardware fault somewhere or a BIOS setting that is contributing to the problem and found none.

I just wish that there was someway of getting rid of the Windows 98 Picture so that I could see each item being processed / loaded etc. like you can with most linux distros (which actually flags up potential problem areas in red).

If I could find where all of the componants of this driver file reside I may be able to remove them.

I tried google regarding the CD / driver and and found no references ( hardly suprising so many years after manufacture).

I should have stated in my initial post that the CD is not only external would have been connected by a serial cable - not U.S.B

To this end I have also examined the status of the serial / parallel ports whilst in Device Manager.

Additionally I used the HWINFO /UI tool via the Run prompt to run a check - nothing abnormal was detected via this tool.

I did wonder if installing my new CD / driver et al might actually resolve the problem possibly by overwriting - but I doubt it. I suspect that it would complicate matters further !

Anyway I am grateful for the assistance that has been offered.

Trevor

Install TweakUI. Then, under boot tab, uncheck "display splash screen while booting". Or just press ESC while booting.

Another thought. Take a look in c:\windows\system\iosubsys

Sometimes old drivers get left there and can cause problems. Look in their Properties (Version tab/Company Name or Product Name).

Looks like config.sys has been copied from a boot floppy. Rename config.sys to config.old and restart computer.

That looks suspiciously like the config.sys found on a bootdisk - is this the one from c:\config.sys or some other location?

I ran the search utility to locate config.sys whilst in Windows (primarily because the \ key is not working under pure DOS which makes life very difficult in a command line environment!)

The only file that was located in response to my search query - config.sys was actually c;\windows\command\ebd\config.sys
(I am sorry that I did not see this at the time - it was very late).

However just using the search query: config
revealed the following files:

c:\config.de~
c:\config.bak

c:\windows.config.txt (just a read me re: late changes to Windows 98SE)

c:\windows\config (File Folder)

Iconfig

msconfig

c:\windows\config.sys (already posted contents)

c:programfiles\connectionconfig

I have opened c:\config.bak and this contained the following lines:

Device=C:\WINDOWS\SETVER.exe
DEVICE=C:\WINDOWS\HIMEM.SYS
DOS=HIGH


DEVICE = C:\EPIACD.SYS / rO / w0

Device = C:\ASPICD.SYS / D:ASPI_CD

___________________________

I also opened the C:\CONFIG.DE~ file and that contained the following lines:-

DEVICE=C:\DOS\SETVER.exe
DEVICE=C:\DOS\HIMEM.SYS
DOS=HIGH
FILES=30

____________________________

I have re-checked the folders on C:\ (using Windows Explorer) and there is no file labeled simply C:\CONFIG.SYS (which surprised me).

Any further ideas would be most welcome.

Thank you.

Trevor

I would just add that I have examined the hardware & BIOS settings (directly and via Fresh Diagnose)and no problematic settings (or componants) have been identified.

I have also run a virus scan as a matter of course.

Although I used the method suggested (Esc Key) to get rid of the Windows splash screen at boot up I regret that no text was displayed ( bar these four C:> Prompts I mentioned previously).

I really do wish that there was some way of making Windows boot in the same manner as Linux where you can watch each process being loaded etc. - it makes life so much easier in these circumstances.

By the way I am not anti-Microsoft or particularly pro-Linux it is just a feature of Linux that I think is particularly useful when troubleshooting many faults.

Once again I owuld like to take this opportunity to thank all of you for the assistance rendered.

I haven't gone back through the whole post to refresh myself but I would add the following points:

ebd is emergency boot disk. The config.sys that the system uses is c:\config.sys (but I think you've now worked this out).

There is a step-by-step confirmation. Tap F8 key whilst booting and you will see it as an option in the startup menu.

Windows should start and run without autoexec.bat & config.sys (the right one). They can be disabled by renaming them - most folks change the extensions to .old - that way they can always be restored.

Derek,

There is no C:\Config.sys file

The EBD was identified in C:\windows\command\config.sys file

I had already tried a selective boot before my original post but this did not allow me to identify the precise point where a problem was occuring.

Additionally I did select a Bootlog.txt and examine this with a utility called Boot Log Analyser (which is very useful but has it's limitations).

Whilst I have a reasonable amount of experience in troubleshooting P.C. systems I am not so experienced when it comes to Laptops / notebooks.

This is probably why I am so perplexed by this issue - I do not know what is Normal for a Toshiba notebook.

In my (albeit limited) experience of laptop systems they all seem to be different whereas most desktops seem share many common features (Dell units are sometimes an exception).

I am also extremely confused by the fact that the system does one P.O.S.T. beep and then about 25 seconds later further on in the boot process emits another double beep (which is in an entirely different Tone to the P.O.S.T.)

I have never encountered this phenomena before either with the boot process of a desktop home P.C. or in my experience of laptops.

I can find no reference to this second set of beeps in any of my troubleshooting books or online (via Google).

However thank you for your help.

Dave 01 - I have installed Tweak UI which
is a nice tool but it does not provide for the verbose boot that I require (but at least I can lose that splash screen !).

There's usually no need to 'uninstall' a cdrom driver. For dos, a line calling the driver is installed in config.sys and a line calling mscdex is put in autoexec.bat. Apparently you have no config.sys (except the bootdisk version in the EBD folder) and you REM'd out the line in autoexec.bat.

The only cases where you may need to go through an uninstall process is with older cdroms that had proprietary adapters. Sometimes a separate 'CD-ROM controller' driver would be installed. That was a windows driver and isn't loaded from config.sys or autoexec.bat. An external cdrom may have it's own drivers. If so, it should either show up in device manager or add/remove programs.

It's likely the long boot time is due to something besides cdrom drivers. I don't know if the toshiba has a network adapter but I've noticed with 98 they will add an additional 10 seconds or so to the boot time.

Also in #4 above, the dos prompt lines that appear are coming from autoexec.bat. They're just echoing some blank lines. If you add @ECHO OFF as the first line in autoexec.bat that should stop, although it still may pause momentarily on a dos screen.

DAVE IN CAPS,

Thank you for your post.

I will edit the autoexec.bat as you suggest.

Your comments regarding Network Adapters are interesting.

I creatd a Bootlog.txt (via F8 Key at boot up)which I analysed using the utility program Boot Log Ananlyser.

I checked the box marked Show Failures and this revealed:-

LoadFailed = ndis2sup.vxd

This is the network adapter.

Thre is an article regarding this issue on the Microsoft support site:

http://support.microsoft.com/kb/q127970/

and also on Computing.net (of course ! )

http://www.computing.net/windows95/wwwboard/forum/66985.html

It would appear that whilst this is a failure it need not be treated as a problem.

However this may be what is delaying the boot process whilst a network adapter is being sought - just as you suspected.

Whether this is what then causes the double beep is uncertain (but quite likely).

I am going to try and obtain a manual for this notebook which I suspect will provide enlightenment on this issue.

After I have edited the autoexec.bat as suggested I will consider this issue resolved.

Dave - Thank you for your help.

Everyone who has posted - A Big Thank You !

I have been able to considerably enhance my knowledge thanks to your help and guidence which is greatly appreciated.

Whilst some of the issues regarding this notebook may remain mysteries for ever (the missing Config.sys and the U.S.A keyboard to name but two) this is the cost that comes with buying a notebook for just £8 .

Best wishes and thanks to you all,

Trevor

Missing config.sys (or autoexec.bat) is no issue unless you use DOS programs such as games. Sometime virus checkers have a boot scan in autoexec.bat so it is needed for those cases.

You mentioned USA keyboard. Have you tried Control Panel/Keyboard/Language. If you are from the UK then so am I, so I might be able to help further if necessary.

Derek,

This notebook is curious - it actually has a U.S.A Keyboard fitted( I mean that in the hardware sense of the word).

Perhaps at sometime during it's life something was spilled upon it and a non uk keyboard was fitted as a cheaper repair option.

This should not be an issue as the only difference between the keyboard layouts would be the location of the @ and " key (which are transposed).

However what I do find curious (and problematic)is that the \ key will not work in (true) DOS mode.

Obviously trying to work efectively in DOS ( such as editing a file) is not possible if the \ key is undetected.

When I am working in Windows, as I am a two handed one fingered typist at best, remembering to look in a different place for the @ key and the " key is not a particularly onerous task.

I was tempted to load Linux on it instead of Windows ( Damn Small Linux would be my Distro of choice for this unit).

However as I do not have a ( Bootable) CD drive I would not be able to test hardware detection prior to installation.

Thus I suspect that I will leave it as it is.

Trevor

Well, presumably you've tried switching to keyboard USA in Control Panel.

As far as DOS is concerned have you tried either of these commands from the prompt?:

keyb uk
keyb us

From memory I think the space is necessary but you could try without. I don't think the full path is necessary but if need be you could try:

c:\windows\command\keyb uk
(or us).

Otherwise, yes, sounds complicated, so I am out of ideas.

Derek - Thank you for the advice.

I am certain that when I checked via control panel that the Keyboard was set to USA. However it is not impossible that I overlooked this (or saw what I expected to see) so I will re-check.

Thank you for the advice regarding DOS which was appreciated.

Unfortunately I have found it practically impossible to exit from the DOS command prompt with this notebook.

Previously when using DOS on my other desktop systems I have simply quit the application and program (using the appropriate program command)to return to a C:\> prompt and then switched off power to the unit.

However this notebook will not quit DOS unless I remove the battery and leave it out for a few minutes.

Thus whereas I am usually keen on using DOS to undertake many tasks (I enjoy it's simplicity) I am a bit reluctant to return to the command line on this particular notebook.

However if my courage should return I will certainly try using your suggested commands.

I am still unable to understand why the \ key will not work in DOS as this is identical in both U.K & USA keyboards - another mystery!

When I purchased this notebook I felt guilty for bartering the vendor down from the asking price of £10 to £8 - I do not feel that way any more !!

Once again, my sincere thanks for the interest that you have taken in my problem(s)and the valuable help that you have provided.

Trevor
