I don't have a floppy drive and I want to boot from a cd. Only problem is I can't figure out how to read from a cd.

by the way I did check google.

I figure that you use int 13 and use the right drive number I think. But what would be the cd-rom drive number.

If you wanted, you can just use use emulation to run the floppy image from CD. i.e, using your CD imaging program, just create a new bootable CD, and use your floppy image. MagicISO is great for this.

This is the easy way of doing this though.

What's the hard way.
I'm actually looking more for how to write code for it.

You can do the same thing from the command line: Bootable CD

Oh so your saying that the code for loading from a floppy works the same on cds?

As has been said, that's "the easy way". Check El Torito.

Oh thanks. This clears it up a bit.
