- It is not just drivers that need to be rewritten. Have you though about
- changes required for the different hardware interrupt stack frame,
- interrupt masking structure, the MMU (BTW, the 68000 machines do not
- usually have one of these. This makes the porting task much harder, not
- easier), system call invokation sequence, etc?

- You should read the series of articles from Bill and Lynne in Dr Dobb's
- Journal about the porting of 386BSD. You are basically doing the same
- task for the
- 680x0 architecture as he has for the 80[34]86. After reading the
- articles,
- you may change your mind and decide to wait and start with BSD4.4 which
- already has some support for various 680x0 machines.
