booting NetBSD i386 with grub

Hello,

in a multi-boot setup I need to boot NetBSD i386
with grub. With some google-search I found the
grub docu but I couldn't figure the complete lines.

What I got so far: grub finds the kernel, the kernel
goes through the hw but then falls kind of helpless
and asks for

- root-device
- dump-device
- file system
- init-path (/sbin/init)

I can enter these all manually and NetBSD finally comes
up correctly. Has anyone the complete lines for
grub to automate this and make it simply work?

There has been a bit of a discussion about this the last
couple of
days on netbsd-current list - check gmane if you want to
have a look.

This is my menu.lst file (the first four lines do not work
with the
version of grub from pkgsrc - they are from a Solaris setup,
but don't
cause trouble here):

You get this, if you have kernel --type=netbsd, as in my
entry No.3 .
The parameters do not get passed if MULTIBOOT is disabled in
the
kernel.

The easiest is to use the entry No.1 - chainload. The NetBSD
kernel
does not have any knowledge about grub.

My default entry, as you can see, happens to be No.2 - this
requires

options         MULTIBOOT       # Multiboot support (see
multiboot(8))
options         MULTIBOOT_SYMTAB_SPACE=1048576

in the kernel, you get:

...
 NetBSD 3.99.20 (M0) #2: Sat May 27 00:54:24 BST 2006
        rootmaggie:/usr/src/sys/arch/i386/compile/M0
multiboot: Information structure flags: 0x000007e7
multiboot: Boot loader: GNU GRUB 0.97
multiboot: Command line: /netbsd console=pc root=wd0a
multiboot: 638 KB lower memory, 523200 KB upper memory
total memory = 511 MB
avail memory = 495 MB
...

multiboot messages, but unfortunately there may be some side
effects -
as happened to me a few days ago - if the kernel had
'pseudo-device
ksyms', then netstat would not work. (One certainly could
ask more
questions as to what else doesn't work...)

I guess, use chainloader.

Thanks for the advice, that worked directly
as expacted.
