I'm trying to run a blue and white G3 machine diskless to see how

I've got fairly extensive experience with netbooting and running
diskless, enough to know that minor details can really cause problems.
I'm following the diskless docs as well as this one:
It seems as if the bootloader is being booted OK, but once it's loaded
it can't find the kernel.
This is what I used at the firmware prompt to get the bootloader
0 > boot enet:,ofwboot.xcf
This seems to work.
This is what I get after the bootloader is loaded via tftp:
NetBSD/macppc OpenFirmware Boot, Revision 1.11
(builds%b7.netbsd.org@localhost, Wed Jul 29 21:44:51 UTC 2009)
CLIENT: XXXXXXXXXXXX 192.168.1.3
SERVER: XXXXXXXXXXXX 192.168.1.254 Using IP address: 192.168.1.3
root addr=192.168.1.254 path=/home/sylvester/root
open /netbsd: Unknown error: code 60
The /var/log/messages file does show that DHCP activity is coming from
this client machine, but it shows no errors.
You should see nfs traffic.
I've been fiddling with the dhcpd.conf since it seems like the problem
is in there.
This used to work, even with the busted firmware in my beige G3.
On the other hand, I got similar problems netbooting my iBook G4 and
got around it by having OF load the kernel directly, without
ofwboot.xcf. I'm not sure if your OF version understands ELF binaries
though, and even if it does it will barf on binaries bigger than ~4MB
so INSTALL or GENERIC won't work.
Unfortunately I'm not at all familiar with the boot loader. Any chance
to try an older loader from - for example - 4.0, just to see if it
even tries to load a kernel?
It can't be too busted though, netbooting via ofwboot works fine on
sparc64 and the nfs code should be shared.
