Re: [N8VEM-S100:242] Bootstrapping Lunux on the S100/68K...

I was under the impression a 68000 can't run true Unix because of problems with restarting instructions after page faults.  And that was fixed in the 68010.  Not true?

Not sure if Linux's architecture had this issue or not.

G'Day all,

I spent a bit of time last night planning my approach on the
Linux/68K/S-100 bootstrap solution.

I think I would like to break it down into three distinct phases with
the ultimate goal of a full fixed-disk bootable Linux with memory

So starting with a baby step, phase 1 would look something like this:

1) Build a bare-bones XIP -mcpu=68000 -nommu kernel with:
  1.1) No-MMU support.
  1.2) Hack up a device driver for the Interfacer-4 async card.
  1.3) PPP/SLIP kernel module linked in.
  1.4) RAM disk kernel module linked in.
  1.5) Implement some kind of h/w timer + kernel support.
