Someone help(Linux)

[Eponick]

Ive been trying a couple days now can I cant figure out how to put the bootsector and a kernel into an image.
Ive tried:
dd if=BOOTF.bin of=/dev/fd0
cp kernel.bin /mnt/floppy
dd if=/dev/fd0 of=image.img

Then running the img in VMWare
But it just hangs at startup.
Can someone please help?

So, let me get this straight... You are neither mounting nor unmounting the floppy disk filesystem, and you just expect it to work?

You need to mount the floppy disk to /mnt/floppy before copying the kernel in, and unmount it before taking the image.

The boot sector should be where it should be anyway.
But the kernel might be somewhere on your harddrive then
And can your boot sector handle the filesystem?

I finaly got GRUB to work, but it keeps saying it cant use the kernel, unknown file type or something. Im compiling it into binary but its just not working.
I cant get the sample kernel to compile correct either.
Can someone tell me the args to use for GCC and LD?

There are many tutorials out there for how to do all of this.

If you're using Linux as your development platform, you *need* to know how it works and how to do all the tasks you'll need (creating and writing images to a block device is one such task).

To get your OS to boot from GRUB, it has to be multiboot-compliant. Normally, you'll give GRUB an ELF image, but it can handle binary images if they are multiboot-compliant.

There are no args to use for GCC and LD that everyone needs. I put lots of -W flags (namely -Werror -Wall, because I don't like things wrong with my code) on GCC, and I use a linker script for LD that does everything I need. You'll likely have something different.

In short, RTFM
