M68k Kernel - 2006/06/18 10:53 Hi, I was always fascinated with the old Macs, Sega Genesis’s and Atari STs. This is because the Motorola 68000 Processor powered them.

Now I want to make a kernel that would work on that processor. I have only found the programmers manual by Motorola which is a very good find but I need a way to *implement* it. Like a boot sector or something that can load my kernel into its memory and then execute it. I have a Mac Classic II is there a document or a tutorial to load custom kernels in there? Once I get it to boot I should be just fine.

Can anyone help out?

Re:M68k Kernel - 2006/06/19 11:12 Hi Mike,
my first idea was to just look up how linux does it. Unfortunately the m68k branch (Linux/m68k) however seems to use a technique that start linux from a running system, just like any other ordinary application. That's probably not what you want..
Searching the Linux m68k site, I however stumbled accross an obviously quite new loader called emile, that seems to be capable of booting a linux system nativly from a floppy. It's based on lilo and, even if you can't use it for your own kernel, you might be able to get the necessary information from the code and/or by asking the emile developers for further assistance.

Once I get it to boot I should be just fine.
Now that's the right attitude

From what I can see that documentation about your platform seems to be more than just poor. Writing anything usable probably won't be that easy..

regards,
gaf

Re:M68k Kernel - 2006/06/20 15:03 Thanks man! Well the Mac Classic II is just a starter.
The above links seem to work good and should feed me the information that I need.

Re:M68k Kernel - 2006/08/31 19:03 I've put the Alpha port on the backburner and begun focusing on this port now since I have a Mac Classic II machine. Which is having some isssues but I'll figure it out. I have contacted the author of the bootloader and I am waiting a response from him. I'll post stuff about how this is going as I progress.
