I'm experimenting with Linux once again -- want to use it as a networked workstation. I installed Mandrake 7.1 without a hitch, but ran into problems when upgrading. I followed the advice on the Mandrake Update website, and tried to upgrade the kernel manually. Downloaded rpms, and used rpm -Uvh. Everything worked fine until I rebooted the machine (running in dual boot right now). Got the following error: Booting 'linux' kernel (hd1,4)/boot/vmlinuz-smp root=/dev/sb5 Error: File not found What to do? More importantly, what did I do wrong in the upgrade to cause this? Are there explicit instructions somewhere on how to upgrade the kernel using RPM? Thanks, Bryan ----------- C.
