I am new to Linux. I have installed Debian and am running the 2.20 kernel. I downloaded the network install version.
I would like to upgrade to 2.4 or 2.6. The main purpose for doing this is to run iptables.
So now for my questions: How do I preserve the hardware configuration I currently have during the upgrade? I am not entirely sure of what hardware is running on my computer or what options were used to compile the kernel that I have, but the current kernel works. I have run make menuconfig and was presented with options that I have no idea the correct answers to for my system. Does anyone have any thoughts as to where on my file-system I might find the .config file that was used for my current installation, if this could be used for the 2.4 kernel compile? Or ideas for a safer, albeit larger, kernel configuration that would give me the iptable functionality?
Many thanks in advance.
