it turned out that I need to build a new isolinux boot disk. booting off of the first cdrom for x86_64, apparently does not allow a kickstart over the network. I built and burned a iso from the contents of /isolinux on disk1 and I was good after that Thanks JD --- Bogdan Costescu wrote: From: Bogdan Costescu Date: Tue, 19 Apr 2005 19:01:08 +0200 (CEST) To: Jason DePaul Cc: amd64-list@redhat.com Subject: Re: Opteron 252 install On Tue, 19 Apr 2005, Jason DePaul wrote: > linux ks=nfs:xxx.xxx.xxx.xxx:/var/ftp/pub/kickstart/ks.cfg ksdevice=eth0 I'm too lazy to search HP's site right now, but if these computers have more than one network interface (which would explain the ksdevice presence on the command line), try using ksdevice=link instead of ksdevice=eth0 I seem to remember some opposite order of finding network interfaces between i386 and x86_64 kernels in my own tests, but as I changed a lot of them, I'm not sure anymore - it shouldn't hurt anyway. -- Bogdan Costescu IWR - Interdisziplinaeres Zentrum fuer Wissenschaftliches Rechnen Universitaet Heidelberg, INF 368, D-69120 Heidelberg, GERMANY Telephone: +49 6221 54 8869, Telefax: +49 6221 54 8868 E-mail: Bogdan.Costescu@IWR.Uni-Heidelberg.De
