Update!

Not only had I used tcpdump, but I also captured the entire bootp sequence
with a Dolch network analyzer to see if there was a difference in the way a
rev A and a rev B were sending the bootp request. I didn't look at the sniff
very closely (I preferred the trial and error method in this case) and would
you believe that the problem with the non-booters was in the bootptab after
all? Here's an entry that doesn't work:

:ht=1:ha="00:05:E4:10:E9:7D":\

and the fix:

:ht=1:ha="0005E410E97D":\

I actually thought I had tried that earlier, but perhaps a kill -HUP bootpd
didn't do the trick. by omitting the colons in the ha entry, I am able to
netboot B & W G3 rev A and rev B, as well as my G4 that is also running Open
Firmware 3.1.1

My next trick is to take the custom 1.5.2 kernel I constructed and make the
G3 a stand alone install. Previous attempts to boot from the 1.5.2
netbsd.ram.gz did not detect the IDE HDD, and booting netbsd.GENERIC locks
up the USB keyboard at the login prompt. Any ideas on how to make a CDROM
with my custom kernel on it? When I tried to construct a iso9660 cd-rom, it
is readable from windows, mountable with mount_cd9660 /dev/cd0a /mntcdrom in
netBSD 1.5.2, and I can read the files with dir cd from Open Firmware
3.1.1... I get an invalid disklabel when I try to run boot
cd:0,\ofwboot.xcf. If anyone else has any insight on how to accomplish this,
I'd appreciate the help!

Thanks in advance and a very Happy Holidays to all!

Matt

Just to let you know that I netbooted my Blue and White OF 3.1.1 just
fine following the
howto's, readmes and other posts that you need to find :)

Using a tool such as tcpdump or Ethereal (www.ethereal.com - free) are
very nice for
seeing how far the packets go.

In fact since neither FreeBSD or OpenBSD will run this box it will be
Mac OS X and NetBSD
alone for now :)
