I followed the instructions for making a Bootable Dos CD-Rom (single boot image) [updated! nov 4, 2002]

Now this will work and make a Bootable cd for me but I wanted to add one program to the disk

I added the dos program to to "cds\cdromsi\files\" folder. and made another cd

This cd will not boot at all.

HELP PLEASE!!!!

The file size for this program is 1,367 kb

Do you have a link to these instructions?

http://nu2.nu/bootcd/#cdromsi

I think the main problem is the file size. How can I get more space than the 1.4 floppy space?

Is these a larger size dos iso file somewhere?

The El-Torito floppy emulation standard allowed three size of images:

1. 1.20
2. 1.44
3. 2.88

recently it was found how the above is not true , and the standard actually supports images up to 36 Mb BUT mkisofs won't make them.
Details (including test image and procedures) are here:
http://www.msfn.org/board/topic/152399-on-...oppy-emulation/
IF the 2.88 floppy is enough for your use you can use mkisofs "normally" with a 2.88 Mb floppy image.

Can you profide a link for an 2.88 iso file that I could use?

No.
For several reasons.
The first one is that you don't want/need a "2.88 iso file" you want a "2.88 ima (floppy image) file" which you use, once filled with the whatever you need/want to put on it, to build the .iso file.
The second because the image needs to have a boot sector for the specific OS that you want to use (which you did NOT specify).
The third one is that you should learn HOW to do things.

Now, if you post some info on the actual OS you are running/have available AND which OS do you want to put on the floppy image, I could assist you in making one yourself.

Simplest would be:

Though not really "unique" anymore....

I am sorry but i am new at this and do not understand just what is needed to accomplish this.

I do want to make bootable cd dos disk with some dos programs on it that I can use if possible.

I can run xp pro and a have dos installed on a another hard drive that I can run.

I also have Window 98se

Sure seems like he did.

Topic title: HELP with dos bootable cd and


Does this help? dos

Does it matter if it's ibm dos or compaq dos or dr dos or microsoft dos or freedos?

Yes, it does, as there are several different versions of each, they also have differently named boot files, some may need a specific file order, the corresponding PBR code may (or may not) be able to boot from an El_Torito 2.88 Mb floppy, etc. etc.
As an example, within MS-DOS, all versions up to 6.22 included NEED to have IO.SYS (and possibly MSDOS.SYS ) as FIRST files in the filesystem, later don't (and the command line is simplified).
And this applies to the hypothesis that the image is built by the OP (i.e. it may affect the set of instructions I will give later), BUT since OP asked for a "ready made" image, you may well understand how being my crystal ball in the shop for maintenance I would have NOT been able to fulfill the request, even if I wanted to, or I shoud have produced a few tens of images and let OP choose the one containing the actual OS he wants to use.

@tuc
Go here (already given):
http://www.nu2.nu/mkbt/
download the mkbt.
READ the page, when you get to "How to build a bootable 2.88MB floppy image file (without the drive)" click on it, you will land here:
http://www.nu2.nu/bfi/
and download the bfi.

You should ALREADY have a 1.44 Mb bootable floppy image of the Win98/DOS7.1, let's say that it is in C:\myimage\w98floppy.ima.

1. Have a subfolder in it like C:\myimage\contents\
2. put in C:\myimage\contents\ ALL the files you want on the 2.88 floppy image, including the dos 7.1 system files
3. extract mkbt and bfi in C:\myimage\.
4. open a command prompt and navigate to the folder.
5. issue:
   
   
   CODE
   mkbt -v -c w98floppy.ima bootsect.bin
   
   [ENTER]
6. a new file bootsect.bin will be created, 512 bytes in size.
7. Now run:
   
   CODE
   BFI -v -t=288 -b=bootsect.bin -f=my288.ima C:\myimage\contents\
   
   [ENTER]
   
8. Done.

Hello,

to manipulate Dos floppies you need few tools:


http://www.winimage.com/winimage.htm

http://www.winimage.com/download.htm
http://www.ezbsystems.com/ultraiso/
http://www.isobuster.com/

http://www.imgburn.com/index.php?act=download


run all your DOS floppies (images) from a bootable CD :

http://www.ultimatebootcd.com/

Nero can make a bootable CD from a bootable floppy image or Disk.
http://www.nero.com/enu/downloads-nero11-trial.php

there are also lots of Links to (ghost) bootable CD and floppies on this forum
go down the page and choose hot topic

Regards Ben

@Ben_Mott

Noone of the tools you mentioned are actually *needed*.

To access/modify/create a floppy image under XP or later there is IMDISK:
http://www.ltr-data.se/opencode.html/
or Ken Kato's VDF:
http://vfd.sourceforge.net/
But as seen the mentioned command line tools by Bart are OK for what was asked.

Gilles Vollant (Author of the Shareware Winimage) provides also a Freeware "Extract" that can do many things with images:
http://www.winimage.com/extract.htm

In pure DOS, worth mentioning is DCOPY:
http://users.telenet.be/jbosman/applications.html


Almost *any* Freeware burning app can do (with much less bloatware) what Nero (Commercial) does.
The suggestion is for IMGBURN:
http://www.imgburn.com/
which is lightweight AND freeware.
I know you mentioned it , but it should be something like:



Unless I am mistaken, Nero 11 is currently over 360 Mb of bloat (compared to less than 6 in latest - already bloated - version of IMGBURN)
Previous versions:
http://www.oldversion.com/ImgBurn.html

In the mentioned thread:
http://www.msfn.org/board/topic/152399-on-...oppy-emulation/
there are links to a couple lesser known CD burning utilities that allow the making of "supersized floppy emulation" CD's.

As a general rule, .iso files should NOT be edited, expecially bootable ones, unless you know where your towel is, it is usually faster (and definitely safer) to re-create the .iso than to edit it.

hello again ,
thank you for the information.
here is a good instruction how to use imgburn to make a bootable CD.

I STILL NEED HELP!!!!!!

I do not get it it.

I have made many bootable cds that boot but NONE of them have the added program on it that I want

I just tried the ImgBurn and got the same results.

Can some give me step by step instructions? I have invested hours into this and still do have it right.

See this posting for that. http://www.911cd.net/forums//index.php?s=&...st&p=170272

How many steps did you do? What was your result of each step?

Compare with the standard litany:
http://homepages.tesco.net/J.deBoynePollar...ard-litany.html
Right now you are in the "I'm ill, doctor. Help!" stage.

Unless somehow you do not make clear WHAT the problem is and WHAT you have done, there is no way anyone can help you.

You do not pay a fee per word you post , without being verbose you can well post the EXACT DETAILS.

I posted some EXACT instructions on how to make the 2.88 Mb boot floppy.
Did they work? (report as per Ed_P post above)
Have you checked the floppy contents?
Have you tested it in a VM?

Or the floppy is OK but the issue is making the .iso out of it?


jaclaz

I know this is STUPID but I did all that without any errors but now what!!!!!!!!!!!!!!!!!!

SORRY BUT I do not know the next steps

This is NOT AT ALL "stupid" , it is "LAZY" (which is different).

If Ed_P asks you:


You should reply posting the §@ç#ing result of EACH §@ç#ing step , AND NOT:


Personally I use a (rather common) convention along which if I add at the end of a sentence a small hook sign like "?", it means that that is a question for which I NEED an answer (to better understand YOUR problem and try and help YOU).
Now I posted 4 (four) of those:


For which I would like to have 4 (four) corresponding answers AND NOT:

Which may be - possibly - a very unpolite (you should NOT SHOUT at people that are only trying to help you ) answer to ONLY question #1 (or you may need a complete overhauling of your keyboard, as you seem to have the exclamation mark key STUCK ).

Comeon, it's not the difficult, I assume (I can do nothing but ASSUME) that you have succesfully built the 2.88 Mb boot floppy image.

Now you (probably) need to create a bootable .iso out of it.

Ben_Mott kindly posted a link to a video illustrating HOW to do that.
Had you spent 5 (five) minutes on the IMGBURN site, you might have been able to find this step by step tutorial with pictures:
http://forum.imgburn.com/index.php?showtopic=1779
now if you VIEW the video and READ the above post you shoule have no problem whatsoever.
OBVIOUSLY, since now you have a 2.88 Mb floppy image you DO NOT want to select "1.44 Mb floppy image", but rather "2.88 Mb floppy image".

Please do understand the fact that IF - by any chance - the answers to questions #2 or #3 are either "No" or "I don't know", there is NO point whatsoever in attempting creating a bootable .iso from a possibly NOT bootable floppy image.


jaclaz

I am sorry if I offended anyone. As you can tell I am very new at this.

I did not know how to use the ima image file to make a disk.

Yes the video did the trick - I now have a bootable cd with the files I want on it.

Thanks for putting up with me.

I have one more question - how can I get more than the 2.8 size?

That's the tricky part , you need to go back to post #6:
http://www.911cd.net/forums//index.php?sho...=24663&st=5
and follow the given link.

It is a rather new (and "advanced") approach BUT all the needed info is in there.

READ the whole thread (you will need some time).

Basically:
go here:
http://www.msfn.org/board/topic/152399-on-...on/page__st__27
and get a pre-made 36 Mb floppy image
go here:
http://www.msfn.org/board/topic/152399-on-...on/page__st__34
and read it (you need to "populate" the image with the files)
go here:
http://www.msfn.org/board/topic/152399-on-...on/page__st__44
and try the experiments in there

If you have SPECIFIC doubts/questions, feel free to ask about them , possibly SPECIFICALLY and providing meaningful details.


jaclaz

. You didn't. You may have annoyed our curmudgeon but we all do at some point, some repeatedly.


Excellent!!


Kids today. You give them an inch and they want a yard.

And the curmudgeon RARELY gets offended , at the most he becomes grumpier than usual and starts SHOUTing


Naah, kids today. They are used to LUXURY, Why, in MY day .... :

Check the size of file every file copied in new cd or not.
