Re: ELKS on Amstrad PPC 512

[Dan Olson <dano@agora.rdrop.com>]

It took me a minute, but I finally figured out what makes this system
"different" enough that it won't run ELKS, it only has 512k of RAM!  This
may not mean that it's impossible to get ELKS running on this system, but
the pre-compiled versions of the OS expect 640k or RAM.  I suppose someone
else can better answer this, but I believe there is a kernal option that
can be changed at compile time to use less memory.  Being a laptop, I
suppose sticking a little more memory on the bus isn't that easy (on a
machine with ISA slots, a memory board could be added).
