README for Prisma 40 kernel patch set "p40-030801.diff"

These patches add support to run Linux/m68k on the Isicad
Prisma 40 diskless workstation. The diffs are against the
Debian 2.2.17 m68k kernel. The Debian kernel was built as
follows:

From ftp.debian.org in directory:
  /pub/mirrors/debian/dists/potato/main/source/devel/
Get the 2.2.17pre6 base kernel:
  kernel-source-2.2.17_2.2.17pre6.orig.tar.gz
And apply this patch:
  kernel-source-2.2.17_2.2.17pre6-1.diff.gz
Then get the m68k patch set:
  kernel-patch-2.2.17-m68k_2.2.17-0potato1.tar.gz
Unpack it and apply the contents in this order:
  2.2.17pre6-2.2.17.diff.gz
  mac68k-2.1.17-20001116.diff.gz
  bvme6000-rtc.diff.gz
  mvme147-config.diff.gz
  mvme147-initrd.diff.gz
  mvme147-scsi.diff.gz
  mvme16x-rtc.diff.gz
  serial167.diff.gz
  genhd.h.diff.gz
  8390.diff.gz
  NCR5380-reselect.diff.gz
  atyfb.diff.gz
  clgen.diff.gz

The Prisma 40 patches should then be applied using 'patch -p1'.

This is the first release of the Prisma 40 kernel, it has the
following features and bugs:

Features:
  Boots with root over NFS (tested using a Redhat 5.1 userland
    copied from an Amiga).
  Serial console on 'data terminal' port.
  Serial mouse on 'joystick' port (mouse port seems to have a 
    hardware fault on my system).
  Framebuffer support but no framebuffer console yet.

Bugs:
  Serial driver is a horrible hack, needs a complete re-write.
  No keyboard support.
  No boot-time hardware detection.
