Apparently, you can't put a 10 mbps hub between a 10/100 Netgear switch
and a 10mbps network card.  Taking the hub out, I got network booting,
NFS root, to work.  I guess I'm going to have to buy another switch to
replace the hub.  I thought that the hub made no difference, but I guess
the switch isn't smart enough to transmit at 10 mbps to a hub where it
is smart enough to transmit at 10 mbps to a network card.  I figure that
this isn't a bad hub issue because I tried another one.

I could ping in both directions even with the hub, but that didn't mean
that the hub wasn't a problem obviously.

BTW:
There seems to be a bug with dhcp, the linux kernel, or pxelinux that is
really annoying.  The root path gets ignored consistently and the kernel
boot defaults to /tftpboot/<server_name>.  I got around this bug by
making links to the proper directory named after the machines, but this
is sort of an ugly kludge.  I thought that my backup dhcp servers were
to blame, but unless the order of the options is the problem, all three
servers have the root path option.  Anyone solve this problem?
