First let me thank you for udpcast, it has been a valuable tool for my school district. And now to what I'm here for, we have gotten a new batch of computers from Gateway with Marvell nic cards not supported with the current version of udpcast. I have attempted to build a custom iso with these new drivers following the instructions on the website. I used the 2.4.26 kernel sources and the rpm's from the site. I can't get the computers to boot to determine if the new drivers work. I'm sure I've just overlooked some small detail but I haven't been able to determine what. I downloaded the linux driver from the Marvell site; installed in 2.4.26 src tree and built kernel according to instructions on the site. I created the iso with the following command: ./makeImage -k /usr/local/lx/2.4.26-udpcast/linux-2.4.26/arch/i386/boot/bzImage -c udpcast1.iso --fullbox the resulting iso is then burned to cd and when booted gives the following error: Please append a correct "root=" boot option. kernel panic not able to mount root Thanks, Michael -- Michael Williams Haywood County Schools Technology Director Instructional Technology http://www.haywood.k12.nc.us (828) 627-8314
