This is my first attempt at building an operating system and my first release. Any Testing or help with the project would be appreciated.

Thank You for you interest.

Tested in Bochs, QEMU, Virtual PC, and VMWare.

QEMU:

A lot of hex numbers and then some information about floppy drives. Appeared to freeze at "reading..." though.

Bochs:

Many more numbers than QEMU printed. Seems to be stuck just printing numbers, and then it makes it past the "reading..." text to read in the bootsector et al. Made it to a shell (the floppy drive is still spinning, btw).

I like the output from "ls", especially the dates - though I'm not too sure about "_~1.TRA" - that might be a deleted file that you haven't checked for in your directory parsing code.

I got confused when I tried "read", as I thought it was like "cat" - where you have the file passed on the command line (Also, it couldn't find test.txt?)

Virtual PC:

It worked well (hardly any numbers output). Much slower to read the floppy though, have you thought about caching the read directory listings and updating the cache whenever something needs to be written? Other than that, it ran smoothly.

VMWare:

Pretty much the same as VPC.

It seems to be a very good first attempt (I am interested to know how much is actually your code though) with a couple of things that could be fixed up (mainly that directory code).

Also, if you type special characters the command doesn't match properly, and you can also backspace into the ">" .

Good effort

Virtual box seems to develop the same problem as QUEM

Thank you for your interest, All of the code is mine but it used Brian's os development tutorial to get me started. Ive made some changes to the code and would appreciate any testing that you could do, for comparison. Thank you for all your feedback.
modified version:

Thank you

well just about everything worked fine. the LS command didn't though, it locked up the OS and I had to reset it.

your shell seems to be sturdy enough, i wasnt able to do any simple overflows.

just FYI, if you enter a command name, and then press any other key, even if you delete it, the command doesnt get registered.

i hate to break it to you... but its not ALL you and Bran's code. Theres lots of stuff from other tutorials on osdever.net in there:

floppy detection, some of the floppy read/write

i swear i've seen some of the CPU detection somewhere too...

on the plus side, the code that is yours looks pretty nice.

Test:

froze on "reading..." when i tested with Qemu (windows default binaries)

bochs successfully read the floppy, quite quickly actually (which is impressive). Shell seems to be secure, but your read command didnt seem to work for any file. It also failed to give me any errors. your format command also failed on bochs.

Thanks for spotting that lukem95..

@xarnze, You're making use of my CPU detection code, but you're clearly violating my licencing agreement.

I didn't ask for much, all I asked was that you retain my licence... it's not permitted for you to strip my licence off like that and introduce your own, both morally and legally.

You don't even add anything to the existing code base to warrant your name to be listed in the copyright notice.

I ask you to replace the header with the my original licence, and discontinue distribution of the unauthorized relicensed files.

Many apologies Brynet-Inc, i was given a copy of your code without the header on it the code has now been given its proper header. Almost all of the code that has been pointed out by lukem95 is no longer present in my code base as it was only included in order to test other functions i was writing until i had re-written them, these sections have been rewritten but unfortunately i submitted an old copy of the code to CVS and source forge accidentally, I'll update it as soon as possible.
