booting from a network

Hello,

I'm learning NetBSD/mac68k netboot with Booter 2.0.1a6.

My netboot setting(BootP) is based on "Diskless NetBSD
HOW-TO".

http://www.netbsd.org/Documentation/network/netboot/
TFTP server= Quadra800(4.99.4) is going to export
NetBSD-3.1.

With Booter 2.0.1a6, I get;
 >Booting...
 >TFTP transfer  done
 >transparent = 1
 >Boot error: This kernel is not in a format which the
booter can  
execute.
 >***** Boot Stopped. *****
 >Restoring Monitor settings...
 >Boot error: kernel_parse(COUNT_KERNEL) failed

I tried some kernels(netbsd-GENERIC.gz or netbsd.GENERIC.gz)
including 3.1, 1.5.2, 1.4.2 and 3.1 kernel gzipped in 1.4.2.
But I got same Boot error.

What is "gzipped ELF kernels (but only gzipped
a.out)" ?,
how can I make it ?

Thanks in advance,
Kazu Inanaga

I've finally got a success NetBoot with Nigel Pearson's
advice.

In the above case, TFTP transfer was 'not' done.
With proper bootp and tftp settings, now I get;
 >Booting...
 >TFTP transfer ............................... done.
 >transparent = 0
 >32 bit ELF format
(snip)
and "login:" prompt.

It's very simple and easy.

 >gzip netbsd
I was fool with "TFTP transfer done".

I also tried "floppy boot", but, my LC475 and
Booter 2.0.1a6
want some Open Transport Extensions. I can't make System
Folder
in a 2HD floppy disk.

NAD + Booter 2.0 in 2HD floppy disk works for BSD device.
NAD + Booter 2.0.1a6 doesn't work for NetBoot server.
OS7.5.5 + Booter 2.0.1a6 in a Zip drive = my setting, works.

HDD does't spin up, (HDD is needed for the internal SCSI BUS
termination, without Power supply). Zip is quiet after
NetBSD
booting up (I can eject Zip), so, my LC475 runs quietly with
large avail space. (LC630 with IDE drive is the server.)


Watching "TFTP transfer ....................
done." and it's
boot sequence is interesting.

Thanks so much to Nigel Pearson for kind advice,
Kazu Inanaga

That is probably a bug I should fix in the Booter, then.
If I still remember how to build and test it

I seem to remember an Apple minimal boot floppy that
had networking support in it, but that may have only
been AppleTalk, and not TCP/IP (Open Transport).

You are very welcome, Inanaga-san.

We should probably get around to importing the booter
sources inti the
NetBSD repository...

I understand, thanks!

In File menu of Booter 2.0.1a6, I see "Open and Boot
...".
(Booter 2.0.0 doen't have it.)
"Nigel's Home Page" / BSD/Mac68k Booter 2.0.0 and
2.0.1a6
http://w
ww.users.bigpond.com/pear_computers/
It works, but I don't have any idea how to use it.


My silly story.
Last month, I made a CCD box with 2 X 1GB old HDD for
/usr/pkgsrc.
That box had one more HDD and 2 big ventilator fans.
... I couldn't sleep at that night because the NOISE!!
(And also, my CCD=interleave was slower than one drive.:p)

Now I have quiet nights with NetBoot (and NFS). Thanks,
again.
I'm going to make 2 or 3 NetBoot clients.
There is an interesting "Some space-saving
techniques" in
"Setting up the filesystem, Diskless NetBSD
HOW-TO".
http://www.netbsd.org/Documentation/network/netboo
t/files.html

I worry about network security.
It's not easy work to setup ssh for NetBoot, is it?
