Ah, yes, I didn't mean to imply that the incompatibility was only
between grub and the console emulation. All (well, ok, that's only
grub, lilo, and pxelinux) the bootloaders that I've tried have wackiness
with the console emulation such that you are way better off just using
their built-in serial support.
Alas, with pxelinux, you pretty much have to do per-box config stanzas
in your dhcpd.conf, so as to either set a specific IP (which would let
you have a special pxelinux config file for them), or use the
You could try the newer combios. I found that it made the pxelinux
stuff somewhat more legible (but not really enough for use).
