Hello Michael, I also work for a school district and have found udp-cast to be a great tool. I believe the problem you are having is similar to a problem I faced recently. Our district uses PXE boot servers but I got the same error you did. Here's what you can try: Open ISOLINUX.CFG on the CD and see if it looks like this: default linux label linux kernel LINUX append root=/dev/ram0 initrd=INITRD Your default, label, and kernel lines may be different but make sure the root=/dev/ram0 option is there. I have never made custom UDP-Cast CDs. I do not know how you would make these changes when making the image. Hopefully someone else will be able to step in and help.

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 ------------------------------ _______________________________________________ Udpcast mailing list Udpcast(a)udpcast.linux.lu http://udpcast.linux.lu/mailman/listinfo/udpcast End of Udpcast Digest, Vol 19, Issue 1 **************************************
