Hi all.
I'm new on asm and os construction. But a senior hll programmer. I'm trying to load my kernel from my own boot loader. But without success. I think that the problem is on a combination of factors, such as use16, ORG 0x7C00, and that my kernel resides in other object file. Some cases, when I make: Code: use16 ; for boot loader extrn labelname call labelname it simply doesn't compile. But, if a make in a test file : Code:
use32
extrn labelname
call labelname
It compiles. More. If I TRY to Code: use32 ORG 0x7C00 ; The BIOS loads the boot sector into this memory location extrn labelname call labelname It doesn't compiles, too. Please, explain WHY this happens. How I can load my kernel written in C from my own asm bootloader? I don't want to link both together. I just they resides in separate binary files. I wanna understand the bits. The code is attached. Please help-me. Thanks in advance. Best regards, Marco Alves.
