cd-rom not working under dos

[achter]

My cd-rom, I found out, is not recognized under dos. I use it fine under win98 but under dos it gives not valid drive spec trying to find the d prompt. I reloaded the drivers and still no luck. What could cause this?

[Ed_S]

When you reloaded the drivers, was this the Windows, or dos, drivers?

For the CD to work in dos, the device driver must be specified in config.sys and the mscdex.exe command must be in your autoexec.bat

[achter]

The dos drivers are in. The config.sys has the device= statement and the autoexec.bat has the mscdex statement in it, but it is still not recognized in dos. I loaded win98 straight from the cd onto a fresh HD. Would this cause the problem? I started with the win98 cd-rom boot disk with the fresh drive. Maybe I am not loading the correct info onto the new HD.

What Ed said plus /?:MXX0001 this string must match in both of those lines. Also if you are still getting the invalid drive watch as everything loads by taken out the echo command and watching as the mscdex.exe is loaded if it doesn't specify a drive letter than either the above is wrong or the driver is the wrong one for this CDROM or the Lastdrive=c is set too low try "z". These are the only solutions I know of for this error.

Post your config.sys and autoexec.bat files here.

My files are as follows:
config.sys

DEVICE=C:\CDROM\SGIDECD.SYS /D:MSCD000

AUTOEXEC.BAT

C;\WINDOWS\COMMAND\MSCDEX.EXE /D:MSCD000

The weird thing is I find the cd fine when I boot to a startup disk.

Two things that can cause this problem.. either you have a parameter problem (ie. /p:170s and I:14 ) or you have the wrong driver.. installed

What to do ... what to do... is to.. first check z:\ see if it works.. if not. .then boot with the win98 cd.. and then see which driver is being loaded correctly by 98 and copy the file and lines off the 98 boot disk.. and put them into the autoexec.bat and config.sys.

Hi Guys,

I think that there are two posts on this so maybe we should close one of them.

From your other thread...

The no valid... line indicates that the driver is not where config.sys is looking for it (c:\cdrom\sgidecd.sys). Do you have a c:\cdrom directory? If you do, does it contain the "sgidecd.sys" file? If you do, it's like jin vitas said, wrong driver. If you don't, you need to get it and place it in your c:\cdrom dir.

you can try adding this change to you autoexec.bat file

C;\WINDOWS\COMMAND\MSCDEX.EXE /D:MSCD000 /L:E

Thanks for the input. Yes I checked the cdrom directory. This is what is stange. In dos the file cdrom\sgidecd.sys is there. But, if I look in windows explorer under cdrom directory it is not there. And, on the driver disk the file is there checked in dos but not in My Computer a: drive

[MadMax]

You can't see it in W98 because you have system files hidden in explorer, no big whoop.

You have definitely got the wrong driver for your cd. Jin Vitas has it again! Follow his instructions about using the system disk driver.

Check back if you don't know how to do this.

Thank you all for your help.
I loaded the oakcdrom driver from the startup disk to the c drive and wrote the appropriate lines for it in the autoexec.bat and config.sys files and it worked.
Wonderful, Thank You

Aftermath...

As I have not loaded Win98(if it ain't broke...) so forgive me if I have made a wrong assumption but...

If Win98 is anywhere similiar to Win95, then loading and enabling these real mode Dos drivers (especially MSCDEX) directly on the autoexec and config would affect the CD-ROM performance in Windows?

Would it not be only beneficial if, upon startup, you directly boot into DOS?

Is there the "dosstart" ability in Win98?

I would personally start a real Dos session (not under Win95) if I had to play something in Dos.

[MadMax]

Yes.

Yes.

Yes.
