Even a single NIC computer does three(3) BOOTP-requests: - BootROM "where to get my kernel-image" request - Kernel "where to get my NFS root" request - FAI "where is the FAI info" request On a multi NIC computer, FAI has to check every netdevice, because the BOOTP server could anywhere. > >I agree we should test if the query is correctly answerd (ie with T17? >options) to stop asking bootp servers. >I also agree that, with my patch, you can query twice on the same NIC. > >Am I broken ? ;) Not complete aware doesn't mean been broken.
