Ther's nothing complex to it. DOSSTART.BAT only exists if you create it. That's all.
And, in fact, by my method, you don't even need it, unless you want the automagic.
Otherwise, just type DOSDVD <Enter> ant the prompt, when you get to it, and you're all set.

BTW, using Exit to DOS.PIF is yet another of the many possibilities to do it, and ought to work, as well.

Thanks a lot Dencorso!
I'll try this as soon as I find time.

My drives are IDE.

I also noticed my config.sys it's written "device=..." and not "devicehigh=..." and someone posted a command starting with "LH mscdex...". Do "devicehigh" and "LH" make any difference?

Short answer: No.
Long answer: If you have EMM386.EXE loaded from config.sys and DOS=UMB, they may, space permitting, load things in the UMBs instead of in low memory, releasing more conventional memory to DOS applications. Most of the time you'll not notice any difference with that, unless you go out of your way looking for it. On the other hand, if you really have a line like DEVICE=EMM386.EXE ... in your machine's config.sys (give it a look), you might as well edit it to read instead REM DEVICE=EMM386.EXE ..., to test your setup without it, because, generally, Win 9x/ME is much more stable without EMM386.EXE loaded, and Windows really doesn't need EMM386.EXE at all.

Short answer: Yes. ;)
Long answer: You have 640 Kb of lower memory available. How much of it is free after booting to DOS? How much memory do you need in DOS for programs you run? Sometimes a few Kb moved to Upper Memory may make a difference, most of the time it doesn't.

Sure. I have used ALGOL programs punched in cards. I have used QEMM. And I like a finely optimized DOS setup with UMBs. But, by now, as most of the time I'm in Windows (9x or XP), when I do want such a setup, I boot from a floppy.
I have banished EMM386.EXE from my config.sys some years ago and have no regrets whatever about it. :yes:

For what it's worth, here's a pointer (link) to a freeware program capable of opening and closing the CD door in DOS, and to another freeware one that does precisely that in Win, too, just in case. I find them pretty useful, so I think maybe so will you, too.

OK, Fred, I did some testing, and here's how it's done:

=============
Preparation Steps:
=============

1) Download DEVLOD7.ZIP (from the great Jim Kyle himself!), grab just DEVLOD.COM from inside it and drop it into the C:\WINDOWS folder.
2) Go to this page at cdrom-drivers.com, scroll down, complete and send the Re-Captcha, download Oakcdrom.sys and drop it into the C:\WINDOWS folder, too.
3) Go to this page, download SHCDX33E.ZIP, grab just SHCDX33E.COM from inside it and also drop it into the C:\WINDOWS folder.
4) Open notepad, copy the quoted text below to a text file, save it as DOSDVD.BAT and drop it into the C:\WINDOWS folder, too.

@ECHO OFF
C:\WINDOWS\DEVLOD C:\WINDOWS\OAKCDROM.SYS /D:MYDVDS
C:\WINDOWS\SHCDX33E /D:MYDVDS

==========
Normal Usage:
==========

1) Go to the Start Menu and "Restart in MS-DOS Mode"
2) As soon as you get to the prompt, type DOSDVD <Enter>
If all goes well, now both your DVD Recorders should be recognized and usable.
3) When you finish, you may simply turn off the computer with the power button, or reboot, or type EXIT <Enter> at the prompt, and this will result in a full reboot (because you've loaded resident DOS drivers, so you cannot just go back to Windows, without a full reboot). Notice that if you type EXIT <Enter> before issuing the DOSDVD <Enter>, in this case you get back to Windows without a full reboot, because no resident DOS drivers were loaded yet, so a full reboot was not needed.
4) If this procedure fails to work OK for you, my first guess is that your internal DVD-Recorders are not IDE, but SATA, and in this case, you'll have to substitute OAKCDROM.SYS for another apropriate driver (look for them at MDGx's).
I say this because you've never confirmed (nor denied) that your Recorders are in fact IDE. I'm guessing here.
5) Now, if you don't mind always having to do a full reboot on EXIT, or prefer not to have to remember running DOSDVD every time you "Restart in MS-DOS Mode", before being able to use the DVDs, then simply copy DOSDVD.BAT to DOSSTART.BAT (that also must be located in C:\WINDOWS), and the system will automagically load the DOS drivers for you, every time you "Restart in MS-DOS Mode".
N.B.: I'm also supposing that your %windir% folder is C:\WINDOWS, if this is not true, adjustments have to be made for it, too. I didn't use %windir% in the batch file, because this environment variable doesn't exist outside Windows, that is, in True DOS Mode.

HTH.

I have an IDE CDROM instead of a DVDROM. Would this work for me or would it have to be changed?

It's probably been updated since dencorso made that post. The new version should be fine.

You actually do not NEED that file. MSCDEX.EXE is provided with Windows and should work for your CDROM.

There is some disagreement about MSCDEX vs. SHSUCDX among myself, dencorso, and jaclaz. :angel I prefer to use MSCDEX, they prefer SHSUCDX. But either will work for your project, so it's for you to decide. :yes:

Are there any spaces in this statement? Also I'm going to have to change to SHCDX33F since that file has been updated. I'll be glad when my network card comes in this week and be able to download directly to my Win95 computer instead of shuffling disks.

Actually there is NO disagreement whatever.
MSCDEX is "crystalized" in time to it's last release, which was BEFORE a number of changes happened to the ISO 9660 standard (and it's integrations)
SHSUCDX is continuously updated

If you are in the usual nostalgia trip and want to - say - explore an AOL CD :w00t::
http://www.tomshardw...iscs,11854.html
MSCDEX is more than OK :thumbup .

If you want to access data written to a CD (or DVD) more recently it is possible :rolleyes: that MSCDEX will choke on it.

As said elsewhere :whistle: :

I won't get involved in a flame war about MSCDEX.EXE vs. SHSUCDX.EXE or mkisofs vs magiciso or whatever, they all seem to me like King Kong vs. Godzilla (and JFYI, the dinosaur can get rid of that grown up chimpanzee with one hand tied behind his back, anytime ;))

Well, I don't see how you can say there is no "disagreement" when we still each recommend the opposite program. :angel

However I do agree there is no reason to debate it. But since you "quoted for the record," so must I. ;)

...
MSCDEX has NEVER ONCE failed to work for reading ANY OPTICAL DISC that I have wanted to use.

I see no reason to change it simply based on someone saying "SHSUCDX is better."

And I! I refuse to be the only to resist quoting that thread, although I too see no need to debate the issue! :P

[...] MSCDEX has NEVER ONCE failed to work for reading ANY OPTICAL DISC that I have wanted to use. [...]

But it will, rest assured it will!
And while I agree with jaclaz:

I won't get involved in a flame war about MSCDEX.EXE vs. SHSUCDX.EXE

and I much less want to be the starter of such a flame war, I'll say that the reason for recommending quite strongly SHSUCDX is simply that it was written to be much more forgiving than MSCDEX, so that it can read many optical media that are beyond MSCDEX strict format requirements. Even if you don't feel like testing it right now, do have a copy of it in your toolbox, because, sooner or later, you'll find it quite handy. And because it's open source and very well documented (although you'd have to gather at least three versions to have access to all existing documentation: John McCoy's 1.4b, Jason Hood's 3.02 ...

... and Jack Ellis' 3.03F, which is the current one), confirming it remains supported and actively developed. :yes:

Good :).
But that was three years ago, you have just been told how, besides being "better" :angel, SHSUCDX also uses lots less memory, so you now have TWO reasons to keep nonetheless using MSCDEX.EXE.

Then do me this one favor. C'mon... hit me. Before i lose my nerve. Let 'er rip.... :blink:

Ok, so i can't also mention that although SHCDX33F can be used standalone, it's also integrated and synergistic with that author's CD/DVD driver UDVD2.SYS and his XMS manager XMGR.SYS, all of which take up less memory while having more options than their equivalents and are all in an active state of development? Darn....

To be serious for a moment, i really hope that there hasn't been... and won't be... any kind of war over this issue (i haven't followed this or any similar thread). My feeling is that we're all free to make our own choices, be they data-based, emotion-based, sentimental, aesthetic, political/economic, nihilistic... whatever. After all, on this forum, aren't we all using Win9x, an arguably "outdated" operating system in many opinions, that we struggle to make as useful as possible? Sure, we have our reasons, but in the end, isn't it our choice?

On the other hand, my belief is also that *everything* is always open for debate. Not necessarily to convince any of the posters active in a given thread, but just for the wider dissemination of information and opinion in general. That's one of the ways we learn. And maybe some other person who will read it will get some good info to make a decision on.
