Hello, I currently have SuSE 9.1 Pro PXE/TFTP booting/autoinstalling working great with our 32-bit machines. My problem is that I can't seem to get this to also work with our x86_64 machines. I don't know if there is a graceful way to separate 32 and 64-bit stuff in the /tftpboot directory, so what I initially tried to do was make an isolinux.cfg menu option which specified an alternate (64-bit) linux and initrd, but when it loads the 64-bit kernel and initrd, the machine immediately reboots. I tried to boot it off the 32-bit kernel/initrd just to do the install, but as soon as it loads the data into ramdisk, it goes to a blue yast screen with the message "An error occurred during installation!" (very helpful) Lastly, I backed up the /tftpboot directory and blew it away, making a brand new one from scratch with the 64-bit distribution, and it behaved exactly like it did when I specified the alternate linux and initrd (rebooted). Now this situation suggests that setting up 64bit network booting the same way as with the 32-bit stuff doesn't work with my 64-bit systems, and that there is something special I need to be doing for them. Is there some documentation specific to 64-bit network booting / autoinstalling? Does it in fact differ from the 32-bit procedure (aside from having an x86_64 kernel/initrd/distro/control-files)? Has anyone successfully PXE/DHCP/TFTP/autoinstalled an AMD64 machine? Perhaps it is just a compatibility problem with my hardware? The 64bit systems I'm installing are Opteron 146's on Asus SK8N motherboards (nForce chipset). Thanks in advance, -Charles Smith
