x86 assembly floppy disk driver.

Post by cvdcamilleri »

Hi, I'm writing a kernel in x86, but am getting stuck on the floppy disk driver. How would I read/write to a floppy in pure assembly.
(No BIOS, I'm in protected mode)

The code that used to work some 25 years ago may fail to work on modern hardware.
The BIOS may be your best choice.

What about a hard disk driver?

Check the wiki - there's plenty of information there.

You're making life harder for yourself by using assembler rather than a high-level language, but that's your choice.
