MS-DOS 6.2 bootable cd

Specs: n/a, n/a
I had a search around and found an article of someone mentioning they got MS-DOS installation on bootable cd.

I am wondering if anyone who has done this to let me know how they manage to do this?

Best burning program is Nero Burning ROM. It specifies two types of bootable CD-ROMs:

1. CD-ROM (Boot)
2. CD-ROM (EFI Boot)

I guess if I have the floppy disks then the boot image data is easy to get. However if I only backed up my MS-DOS 6.2 files of the disks then I won't have the boot image data. If the latter is the case, can Nero still do sometime to make it boot up (like grab the Windows 98SE boot image instead). Then we have unseen problems such as whether MS-DOS setup/install requires data from A:\ drive. Hmm...

AFAIK MS-DOS 6.22 looks for the Disk Label of Diskettes 1 to 3 when installing.

NERO - well not much to do with MS-DOS

CDRoast is the DOS equivelent of NERO and can create a bootable CD

PC-DOS 7 was available on CD.

The fact the setup process checks for a disk label is the problem. There's two ways you may be able to get around that:

1) Bypass the setup command by creating a batch file to sys the drive, create a dos directory and then use the expand command to expand and copy the files to the dos directory.

2) It may be possible to edit setup.ini on the first dos disk so it doesn't check the disk label.

Then you'd create a bootable cd with all the dos installation files.

No version of MS-DOS or PC-DOS i have checks for the install label. A base version might not install if the installed DOS is different to the one being installed (ie you attempt to put PC-DOS 6.1 on PC-DOS 5.0).

You can quite simply copy all of the files from the diskettes to a single drive (which can be a subdirectory!), and run setup from there. If the DOS is an upgrade, you can first SYS the c:\ drive with some acceptable DOS (eg PC-DOS or MS-DOS).

For example, i have a cdrom, on which i have the files copied from the various dos versions of MS-DOS 5,0, 6.0, 6.2, 6.21, 6.22, and PC-DOS 5.0, 5.02, 6.00, 6.10, 6.30, 7.00 and 7.00B. You simply sys the c:\ drive, and run the install program from the load directory. So to install, eg pc-dos 6.10, you change to eg

cd q:\base\pcdos\610

and follow the bouncing ball.

It works with MS-DOS as well.

The dream we dream together is reality.

When installing 6.22 from floppies it does check for a disk label. If you use a disk with the correct files but an incorrect label you'll get a message to insert the correct disk. I'm not sure how many other versions also check the label.

I've never tried copying all the files to a cd and installing that way so I can't it wouldn't work. Perhaps having all the files on a single disk avoids the disk label check. The setup.ini file does mention the disk labels so I assume that's where the label verification process originates.

I did it the easy way.
Install DOS and all other progs you want to a small hard disk or partition under 650MB.
Burn a CD with this as the bootable image.

If you need to change anything, image the CD to .iso, open with MagicISO or similar, and alter to suit.

YES but this is a DOS Forum, why use Windows software dw33b............

I personally am still not sure wether the OP wants to:

A: Create an install CD, which autoruns and offers an install menu... (FREEDOS?)

B: A LiveCD, like what is available with Linux distro's

Whatever if this could undertaken under a non Windows/linux/anyotherO/S environment it would be great..

FreeDOS9 Install CD uses Linux to boot/autorun CD so either A: or B: does not seem feasible..

"YES but this is a DOS Forum, why use Windows software dw33b............"

Because the OP mentioned Nero, hence I assumed he was not limited to DOS in his software choices. Many of us have multiple PCs and boot a variety of OS, and DOS has largely changed into a specialist "tool" rather than a primary operating system. Why not use the tools available when none of us is restricted to DOS? If one is a Free Software purist one can still use Linux tools to manipulate FreeDOS files and images!
DOS is cool, but restricting the tools one uses to work with it isn't strictly necessary, nor IMO is mentioning those ways to get a DOS result off-topic. I'm not denigrating DOS in any way, and the use of one OS to manipulate files in another has a successful history.
Barts boot disks and CDs are examples.

Okay, I don't need MS-DOS 6.2 anymore since I found out that the best MS-DOS version was in Win98SE. So now am trying to build a MS-DOS 7.0 bootable CD & installation - BUT for games, not generic.

Here's what I found...

In Win98 \WINDOWS\COMMAND\EBD folder contains the Emergency Boot Disk (without the msdos.sys & ebd.sys files for some reason). I extracted the 1.44MB bootable image from the Win98 CD-ROM just to do complete. This is only an Emergency Boot Disk and not tweaked for games. However it's got a good selectable menu system.

In the Win98 \WINDOWS\ there are two files called:

MS-DOS Mode for Games.pif (XMS loading for games)
MS-DOS Mode for Games with EMS and XMS Support.pif (emm386 emulates EMS in XMS)

When double-click either files, they temporarily swap C:\autoexec.bat & C:\config.sys with optimized versions of autoexec.bat & config.sys for games. Why two different pairs of files? Some games were fussy whether emm386 was loaded and other games didn't like it.

So this is a very good idea to embed the differences in the EBD autoexec.bat & config.sys, since there's a choice menu system already programmed in the EBD autoexec & config.

Just needed to copy emm386.exe from C:\WINDOWS\ & also mscdex.exe (from I also changed RAMDrive to load 16MB (instead of 2MB). Tested CD and it boots perfectly, so user can boot a PC with no harddisk and still run programs that require writing to disk. If the user has a DOS sound card then he can add the drivers to autoexec & config files.

What I want to know is how to install this MS-DOS into a blank C:\ ? Does msdos.sys & io.sys files have to be in the first sector/cluster of the HD? I don't think copying the files directly onto the HD would work?

"dw33b - do you have an answer then to my response parts A: and B: for the OP ???"

I just xcopied (after partition/format/sys) the files over from my hard disk image CD. No menu required since all the tools are there.
In Nero, use the under-650meg hard drive image as your bootable image file.
If I were doing more installs I'd Ghost a loaded hard disk and burn to a floppy emulation CD using Nero.

For a live CD the hard disk image works OK. xmsdsk.exe is handy for setting ramdrives.
No reason you couldn't make a live CD that also had ghost.exe and a Ghost image if you wished. Winimage, MagicISO, etc are useful for adding and subtracting files in your base .iso.

To test your .iso, boot in Windows QEMU.

Windows QEMU is nice for testing live CDs, and you can download any DOS, Linux, or other live .iso to try out.

Thanks to the many posters without whom I wouldn't have found out about any of the above nearly as easily! :)

You did not specify "from scratch" earlier, nor did anyone else require "scratch" and exclude other options. I assume "scratch" meaning using purely DOS tools. Too much like work for me when quick and flexible alternatives exist to get a happy DOS net result.
I explained what I did (installed DOS to a small hd, imaged that to CD, and used that to xcopy itself to hd), and mentioned that Ghosting is also a valid install option.
I explained that the imaged drive on CD functions as a live CD, which it does nicely.
I added that you can use QEMU to test the result. That is a worthwhile option instead of wasting CDs.
Thoes "cobbled together bits and pieces" are standard, very common software tools.
Assuming OP has a Winbox, the methods above would be ways for him to easily whip up live, install, and live/install CDs to his taste.
They produce DOS CDs of whatever type one may wish, so what do you take issue with?
If the OP wanted an install CD, I answered that (less having a menu, but he didn't ask for one).
If he wanted a live CD, I answered that too.
With the tools above, OP or anyone else can swiftly add, remove, and change files in their gaming DOS CD image, test it, burn it, and enjoy themselves playing old school games.
