How are you?

I have used NetBSD/mac68k-1.2 on IIsi.

I can have used commands (ps, vmstat).

Then, I install GENERIC-20 from
ftp://ftp.netbsd.org/pub/NetBSD/arch/kernel/ to my IIsi.

But, I can't use command (ps, vmstat).

  #ps
  #  kernel size illigal...
  #vmstat
  #  not find __????, __???? in kernel

And, for I do compile kernel, I use 'config' command in
/sys/arch/mac68k/conf.

But, error error error... and stop.
  #config GENERIC
  #can't open arch/mac68k/conf/....

I want to do command(ps, vmstat).
I want to do compile kernel.

How to do?
