Freebie Operating System
AWESOME NEWS: Romtoc (not on Scratch) has made us a mirror site! http://bucuresti.romtoc.net/mirrors/freebie/!
Hey guys, I'm making an OS called Freebie in assembly. I just started it today (11-20-11), so it isn't much yet.

Website:
freebieos.tk (freebie.goodluckwith.us)
How to edit:
Download an 8086 assembly editor (such as emu8086) and open the .asm file in the source. That's all you have to do!
Download source:
Version 0.0.2: http://freebie.goodluckwith.us/0.0.2/fr … rce002.zip
Version 0.0.1: http://freebie.goodluckwith.us/0.0.1/fr … rce001.zip

DB new_line, 'Press any key to reboot this computer.', 0 ret
Basically, since it is so simple right now, it has a simple script (which BTW you can boot to if you put it on a floppy!) which includes the boot record (needed to boot to), and some lines of code that tell it to print some text on the screen.

Well, you have to compile it and put it on a floppy, or you can use the emulator in emu8086.

Yeah but what if I don't have any compatible floppies I'm not using? Huh?!

Compile it into a .ISO and make a empty virtual PC in VirtualBox, and finally, load the .ISO into the virtual machine.

This could help me with writing WindozeNT Software Operating System...
Ever since Misc was killed, I've pretty much stopped going to Scratch Forums...

Sorry dude (msdosdude) but after this statement, this isn't that cool after all
I'm gonna dump that code after I learn more assembly.

Re: Freebie Operating System
Really cool. That website you got help from is really old. You know assembly Operating Systems can be booted without a floppy right? I am going to try it with a disk...

Re: Freebie Operating System

It only existed to right for a really old computer processor!
Intel 8086
