Re: PXE boot and kernel module
Are you sure that plain Pelican 1.8 does not work? I don't know the details about this NIC, but Intel NICs usually work without any trouble. The I/O errors you see suggest that your CD/DVD drive may be dirty/loose cable/etc. It is possible to use a USB stick, just search this forum for "USB" and you'll get some hits. However, using USB will still leave you with the NIC problem, assuming that plain Pelican will not work.
I think there will be trouble trying to get the nodes to PXE boot if the driver must be compiled from source, since the kernel supplied to the compute node will not have the driver, and it will be difficult to figure out how to provide it to them. This situation does not fit into the scheme used by Pelican, and I really don't have a good idea about how to work it out.
Seeing the boot splash on the compute nodes is normal, you don't need to touch them, they will boot up after a brief period. The reason there is a pause is that it gives the opportunity to pass boot parameters.
Good luck!
