I'm having boot failures from the DVD ISO I wrote. Did get the boot to work one time and validated that the DVD image was good. Then remembered that I had not saved off a couple of files and I have not been able to boot from the media again. It complains that it can not open VolGroup00/LogVol00. I did a boot command of: linux root=/dev/VolGroup00/LogVol00 Which is what is in the grub.conf file. This system is a dual opteron with a 3ware raid SATA system. Just in case I did try acpi=off which did not help. The other option I have explored is a PXE boot, but have not found any decent instructions for the set up of this configuration. I put in the dhcpd.conf file: next-server 10.2.2.2; # PXE TFTP server Then copied the two pxeboot files vmlinuz and initrd.img to the tftp server directory. Finally I created a symlink 0A020207 -> vmlinuz.
