I'm finally getting accustomed to using FASM. My original goal in learning assembly was to build an operating system. Does anybody have the following things:

1. Basic code for bootable CDs (CD-R or CD-RW).
2. Resources for beginners to learn how to make their own operating system.

If you take a bootable floppy image, you can burn it to a CD-R or CD-RW by clicking on the make disk bootable option, available in most burn software.
The CD will then be bootable, it works by emulating a floppy, thats how most bootable CD work.

PS: You can also do the same with a hdd image.

It is my code, but you don´t need to make a header. I know what I´ve done, so the other can use this code as they will!

Hi all!!!!

I am thinking of using C + ASM to code my kernel, I have DJGPP for Windows. I use GCC to compile and found a problem.

When I link using LD to produce a flat binary output, the output always 1024 Bytes in size. also, there are always 90h (NOP) added.

When I used Linux version, it didn't.

How to solve this problem?? Can you suggest a better linker that support flat-binaries???

Thanks!
