Booting Floppy to Bootable ISO.

Post by donggas90 »

I searched many pages and wikis but cannot solve my problem.

I have a booting floppy for my OS that sources are almost from this tutorial(http://www.brokenthorn.com/Resources/OSDevIndex.html). However it cannot use when try to test in real machine because it has not FDD. So need to convert CD or DVD thus tried to make an ISO to test before burning. but stucked this step.

That ISO was created with DiscUtils.NET(https://discutils.codeplex.com/) in C# with diskette emulation option. but it doesn't work at all. No emulation option as well. I'm using VMware.

Anyone can tell me step by step to make a Bootable ISO from Booting Floppy Image, Please?
Additionaly, I don't want to use mkisofs. I'm not familiar with linux.

Look up mkisofs and examples of using it.

I would recommend trying to use a USB stick rather than a CD. They're rewritable, and easier to deal with in many ways.

If you do a byte-for-byte copy of a hard disk image or a floppy image onto a USB stick, it will probably just work. I've certainly done this with a hard disk image, I think it should work with a floppy image too, though it might depend on the BIOS of the machine you're trying it on.

If you don't already have a tool on Windows to write to the USB stick, the Raspberry Pi project suggests Win32DiskImager. I afraid I don't remember what I used when I was on Windows - I switched to Linux a while ago, which makes this sort of thing much easier!

mkisofs is available for Windows - have a look at the Under Windows section of mkisofs.

Thanks for advise.

Yes, CD or DVD not rewritable in generally.
but I have some CD-RWs that rewritable. :lol:

BTW, I think CD or DVD is better media for OS.
First reason that many retail OS are selected CD or DVD for their install disk.
Then not rewritable characteristic is can be positive property I think.
because it can guarantee that distributed OS disk will not modified by any other SW or OS.
Someone can hack the disk but it is not general case, isn't it? :P

Finally, I'll using ISO only in developing state. so rewriting is no matter.
I launched a bootable ISO successfully with DiscUtils.NET. Thus I don't need another disk tools anymore.

Thanks!
