[rescue] bootp and dhcp - conflict?

[Dan Moisa]

The conclusion here is that the 3/80 is just slow. It works fine with
SunOS 4.1.1, though for that I gave up on the instructions for how to
set up netboot from the installation files, and just installed to
harddrive and copied the directory structure/etc out of it. Nothing
complex worked otherwise - X, patches, the upgrade.

The main problem right now is that NFS gets dropped after roughly half
an hour. Anyone know what kind of keepalive is needed here? I'm
looking for something that basically keeps the connections open
indefinitely.

Thank you all for your knowledge and patience on this!

PS: for NetBSD, on Sun4 and onwards it looks like boot.net tries BOOTP
(dhcp) first, which on modern stuff gives you nothing. It's relatively
easy to change the code to move bootparams first, which makes
everything work like butter on an unsegmented network.
