PXE booting 7.0-R

Mon Jun 9 06:50:47 UTC 2008

I've tried also specifing the IP for root-path, but as it seems, the hosts
defaults to server-name or next-server (these are the same for me), so it's not
neccessery to specify the IP in root-path.

Also the fileserver and the dhcp server are the same. You should have seen this
in the included config I gave.

Furthermore, meanwhile we've noticed that loader fails to get the pxe variables
when the onboard raid is enabled, and it notices the PXE environment when the
disks are not included in any RAID setups. Quite strange.
