Programming with NASM / Re: debug nasm os

« Last post by debs3759 on March 13, 2019, 11:00:05 PM »

If you want to see a fully documented FAT12 bootloader in nasm, check my thread at https://forum.nasm.us/index.php?topic=2265.0

It reads a text file from the floppy (it can be very fragmented) and displays it. It is easy to change it to load and execute a second stage loader, and converting it for FAT16 or FAT32 would be trivial. I need to get back into coding and update it, my OS died when I got too ill to code.

Dunno. Consult the Bochs documentation?

Hi serrrgggeee.

Welcome to the forum.

Why are you looking at code you don't understand? An OS is an advanced project. Not suitable for a beginner. You'll only frustrate yourself! I strongly suggest starting with something simpler and working your way up.

Having said that, the MikeOS page:
http://mikeos.sourceforge.net/handbook-user.html
seems to suggest Bochs for debugging. Good luck!

Best,
Frank

Programming with NASM / Re: Compiling subroutines only when needed

« Last post by RuudB on March 08, 2019, 06:02:24 AM »

Hallo Frank,

You can "%include" files, ... I guess I didn't make that clear...

No, you made that very clear. The problem is, I already have this file with goodies. If I just pick the needed subroutine, the original COM is just a few hundred bytes. If I include the file with goodies, it becomes 19 KB. 19 KB doesn't sound much in this time but when having to work on a Commodore PC1 with just one 360 KB floppy drive, size does matter.

But just in case I did misunderstood you, I'm sorry and any help is welcome!

Hi Ruud,

Right, "-f bin" does not produce a linkable format. You can "%include" files, or if you want to assemble the separate files first, "incbin" should work. "global" doesn't work ether but is silently ignored - really should be an error or warning. I guess I didn't make that clear...

Best.
