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
The 2.6 kernels apparently don't accept "symbolic" names for root devices (such as /dev/ram0), or at least they don't with the .config that I am using for udpcast. For the 2.4 kernel it is just the contrary, oddly enough (understands /dev/ram0, but not 01:00)
Today's udpcast release adresses the issue by passing a numeric root device identifier (root=01:00) if the kernel is a 2.6 kernel and symbolic (root=/dev/ram0) if 2.4.
Could you try whether it works better with today's version, and if the problem still persists, could you post a more complete error message (say, the 5 last lines displayed before the panic)
