Tutorial Not Working!!!

[PlayOS]

Hi,

Has anyone got the tutorial about paging to work. http://osdev.neopages.net/tutorials/paging.php I dont think that it does work, I have tried it many times but without luck, does anyone know where there is some decent and working code.

Thanks

i have pg setup that works at
http://cvs.sourceforge.net/cgi-bin/view ... cvs-markup , http://cvs.sourceforge.net/cgi-bin/view ... cvs-markup ,
http://cvs.sourceforge.net/cgi-bin/view ... cvs-markup

but i'm not sure this is simple enough to be considered as a tutorial ... According to me the tutorial *should* work.

I have tried this tutorial and was unable to get it working, even though it appears to work like the code that playos posted.

hmm, just in case:
- do you have A20 line enabled ?
- do you have a page fault handler (just in case) and a correct IDT ?
- do you have a hamster (err .. no, this don't qualify ;p )
- do you have 0-aligned DS (otherwise, address translations are required) ?

[PlayOS]

What is meant by 0-aligned?

[Pype.Clicker]

What is meant by 0-aligned?

i mean the base of your segment is 0 (and thus logical addresses - as NASM assemble them - are identical to absolute addresses - as the CPU need them for some special registers like GDTR, IDTR, CR3, etc.)

[PlayOS]

In that case my DS is 0 aligned, however when nasm assembles the file I have [ORG 0x20000] because my second stage loader is put at 2000:0000, does this cause a problem?

Yeah i too tried it and couldn't get it working

Hey, if you can't get it working email me. My email is all over the site([email protected]). I will mess with the code ASAP and try to figure out what the problem is with it.
