Hi
Sorry on my bad english !

I have COMPAQ Quick Restore CD.. This CD is for reinstalling operating system on computer if something goes wrong or u just want to reformat ur hdd..
Actually when u put this cd in ur cd rom drive, and reboot computer, it boot from this cd instead from ur hdd..

I know its bootstrap that is on CD, and maybe its made in assembly. What I dont understand actually is how this thing work ?

When u boot from this CD , u can see some blue screen, and informations, etc etc.. and this thing work without any operating system..

So, is it just regular EXE file on cd that is booted from botstrap, or the whole thing is made in asm ?

Actually my question is, how can I make something like that on normal floppy.. I read a lot of bootstrap tutorials, but all of them just hang computer and thats it.. So I cant figure out how to connect this bootstrap with a program that for example I made in plain C.. ( i found on this forum example in C that dosent need any operating system.. it show simpple "Hello World" on the screen, but author says that u dont need any operating system for that"..

I guess if I compile this thing in exe with C compiler, how can it work without perating system.. but how can I actually connect that thing from bootstrap that I made in asm..?

Huh, i think that I can understand myself now ;-)


I create simple bootstrap in ASM >> I create simple Hello world app in C that dosent require any operating system = how to connect these two things so I can boot that from floppy ?

thanx
