Hello peeps,

I've been creating my own OS for a little bit now and i've finally come to the point where I'm sick of rebooting my computer all the time to see if the code i wrote works.

Until I reach the point where i can work in my own system to work on my own system, i'm stuck having to reboot.

I downloaded BOCHS to solve the problem and it probably would work if i could mount my floppy disk.

The problem is I directly write to the floppy disk using dd for now. There is no file system whatsoever on the floppy. So what do i *mount* as?

As funny as it may sound i looked around quite a bit and i haven't found the information i need. I looked in man too and didn't see anything that would allow me to mount something that doesn't have any file system. Maybe i'm going blind . If my memory is correct, there IS a *mount binary*, but it doesn't seem to work straight off the back. Maybe i'm going numb .

Thanks in advance for your help.

so what your saying s you dd a binary onot the floppy disk ?
well you cant mount anything.

you cant execute a block device, so you will have to dd the file from the floppy to a hard disk.

Well, that might be a problem because the first sector on the disk that is loaded by the BIOS at its usual loading spot loads the second sector of my floppy into memory address 0x10000.

Its not just one binary file; its actually 2. A bootloader and a kernel.

If i transfer the file to disk, then all my references to floppy reading and loading up sectors are out the window and my code just plain won't work.

What i have on the floppy is a bootloader in the first 512 bytes and a small forth kernel that isn't finished just yet in the second sector.

Or maybe it doesn't make any difference and i can make a single binary file out of my 2 binary outputs as if it was ready to be written as a single binary file to a floppy disk and i can tell BOCHS to treat the binary file in question as if it were a floppy disk?

can you not split the 2 binary's with the commands head and tail ?
just a thought.

seems what you are working on is over my head... hopefully someone else with more expertese will find this thead

good luck.

Hehehe,

No, the files are already 2 separate binary files. Hmm well in any case, i'll take care of the binary fusion if need be but, do you know if it's possible to mount a floppy as pure binary ( no file system )???

i dont understand what you mean...
to mount a disk is to attach its file system to the root firesystem.

to mount a disk with no file system is a paradox.

you can access raw data via its block device, but thats it.

Alright, all this gave me a few ideas

Thanks for your help .

Mounting means making it appear as part of the filesystem. So mounting a binary with no filesystem simply is a nonsense.

In your case, your only solution is to access the file /dev/fd0. *This* is your binary. And if bochs has a problem with /dev/fd0 being a special file, then simply dd it to a file in your home, and run bochs on this copy... if it is possible at all.

Good luck.
