That should be easy. Create a floppy image with winimage, then create bootable CD with etc. ultraiso, and use the floppy image as a bootfile.

Edit: ok, i was too fast, it dosen`t work

Why exactly doesn't it work`? Have you tried creating a 1.44MB boot floppy (image) and using this as the image to boot when creating the CD?

I did so with DOS 6, but, with DOS 4- it didn't worked.
I just need to boot it on a floppyless computer to type in "sys c:"
lol
Thanks!

That`s exactly what i did. But all i got was a blank screen when i tried to boot the CD image in VPC 2007.

So... How must I do it?
Or... How can I install DOS 3.3 from Netpune?
It's a dualboot of a FAT drive, and Neptune
I may boot into neptune to mod files, and so.
I'd love to know how to set DOS 3.3 on it.
Thanks!

Any Ideas?

Create a primary partition that is not larger than 32 MB, format it as FAT16, and install DOS 3.3 on it by booting it from a floppy, running "sys c:", copying the rest of the files over and creating a suitable config.sys & autoexec.bat.

It's a Floppyless PC. That's the matter.
I already have a Fat16 32 mb Partition.

I don't think MS-DOS 3.3 supports FAT16. I'm pretty sure it only supports FAT12. However, one of us seems to be getting confused.

It does support Fat16, since it's able to handle partitions up to 32 mb ( I think so )
Windows 1.0x needs a HDD on such format to work functionally.
I've set it up on a bunch of machines, yet, this Floppyless computer seems to me more complicated
What I'm gonna do is to copy exactly all the files of one of the HDDs that work successfully and to set the MBRs to be alike
Hope it works.

MS-DOS 3.0 uses FAT16 but not the final one.
Look here:

That's why I'm using DOS 3.3
It better supports Fat16 and first supports 1.4 mb floppies.
I've tested almost every build I've found of DOS. lol

Wiki wrote: Final FAT16

Finally in November 1987, Compaq DOS 3.31 introduced what is today called the FAT16 format, with the expansion of the 16-bit disk sector index to 32 bits. The result was initially called the DOS 3.31 Large File System. Although the on-disk changes were apparently minor, the entire DOS disk code had to be converted to use 32-bit sector numbers, a task complicated by the fact that it was written in 16-bit assembly language.

The final version of FAT16 is first used in MS-DOS 4.0

Anyway, do you know how to create my bootdisk?
I need Dos 3.3 anyway, I'm pretty sure of it.
Thanks

As I said... I did!

It was a pain on the neck, but it finally worked out amazingly.
I had to use 8 other test images until the successful one.
Now, if u need I can do one for Dos 4 and maybe... dos 2 or 1 (I dunno of those)
This one is DOS 3.3A
