Hi all,

Thanks to a huge patch from Harald (2 lines), the ELF vmlinux kernel
can now be booted from a NetBSD partition, using the new NetBSD bootblocks.

Steps to achieve this:

- Boot a NetBSD 1.4 Beta snapshot (see www.netbsd.org)
- use disklabel to create a small NetBSD partition, and a larger one
  for linux, (and swap...)
- Install a minimal system on /dev/rz?a, with the new bootblocks
- Compile your linux kernel, including my NetBSD partition patch.
- Transfer the vmlinux (ELF kernel, not the nbImage ECOFF image) to
  the root of the NetBSD partition.
- use the boot command below. Please not the dummy first argument
  before console=, the netBSD bootloader somehow eats the first argument.

The box said "Requires Windows 95 or better."
I can't understand why it won't work on my Linux computer.
