Testing the xOS kernel [MY OS!]

This is my new kernel(xOS) that I have been working on for about 3 days now. It is coded entirely in ASM! It is currently just a DOS program (starting at 100h), but is independent of any OS as long as it's a x86. It uses all BIOS interrupts (10h, 16h, 33h). I'm also working on a bootloader to run the kernel, however I haven't had much luck. Anyways the commands go as so:
help: displays help menu
echo: clone of DOS echo command
print: currently broken, but sends text to first printer
cls: clear screen
restart: restarts prompt
quit: (only for dos) but an int 20h to exit
alert: (my favorite) creates a messagebox printing the text typed after the command

If you want to help with this project, leave a comment below :)

[taejamhaha]

is that an OS???

seems to be alike with C++.

seems to be not an OS but a program that runs in an OS

@taejamhaha This is my old kernel, written in assembly, running under FreeDOS. The structure of my kernel is identical to a MS-DOS com file, therefore it can operate in any realmode environment (with the exception of the loading segment being something other than 0060:0000 causing a few memory problems).

@acount134 aw...

so if you're to make an OS...

also think about your hardware.

Windows seems to fit in everything ^^

[acount134]

@taejamhaha well first off it's in Linux, but it's still irrelevant. My code uses the BIOS, but is being emulated through a program called DOSemu. As for hardware, see my latest video for I posted the source in the description as well.

@acount134 please post a video tutorial how you made this!! THANKS!!!!

[acount134]

@taejamhaha Check out my latest OS video. It has the source in the description.

@MrApplseed Sorry for the late response, I use a program called Winimage. Winimage allows you to create virtual floppy images and choose the bootloader option and format the disk in anyway you please.

[MrApplseed]

@acount134 Yup, the bootloader and the kernel are separate. I know I could just write it to the first sector of a floppy, but how do I compile all of this into a floppy virtually?

[acount134]

@MrApplseed Are the bootloader and kernel separate? If your bootloader is your only part of the OS, then just write it to the first sector of a floppy; otherwise you have to choose either to use FAT12 to load your kernel or write in consecutive sectors.

[MrApplseed]

@acount134 Well, I wrote my own bootloader...
