I have a problem:
I want to load my kernel from disk into memory.
I have used a number of boot sectors which all
support fat12 and are capable of loading the file
"kernel.bin" into memory, the trouble is, if my
kernel just waits for a key and then reboots, it
works, but anything else, like printing something
to the screen, it just prints out garbage, ascii
characters.
I've used the same kernel on both boot sectors and
get the same result.
Is anyone willing to look at the code and my kernel
to see for themselves ?
It would be a great help.
Thanks
Oh and the boot sectors are by alex friouze and
i think josh macdonald

Have you got your code posted on the net somewhere?
If you want, you can send it to me at
[email protected] and I can see what I can do.

No garauntees though, dude... I'm workin' two
jobs right now, and don't have too much free time

I'll do my best though!

  It's OK. I can see the problem. You haven't set your data segment register. The foolproof way to do this is:

push cs
pop ds

  If you really want help with this, please go to the OS dev board at http://www.flashdaddee.com. There are plenty of other people over there who will be willing to help you, including me.

Sorry about the   tags, I'm so used to using them to indent my paragraphs when I post that I assumed they would work here, as well!
