io and irq settings in Linux 6.2

Wel, first of all, what do you mean by Linux 6.2? Which distribution is it? Most distributions have different configuration tools.
'linuxconf' is one way to go. Start linuxconf, and go to 'networking', then 'Host name and IP network devices'. Thereyou can fill in the hostname of your PC and the info for the ethernet adaptor. But you may still need the IRQ and IO adress.

One way to find this out is going into windows and looking for the IRQ and IO there. (If you have a dual boot machine that is). But normally the IRQ of all (PCI)cards should be shown at startup, before the system itself starts booting. Otherwise, and this may be the most complete option, just type 'cat /proc/pci' at the shell prompt. You'll see all info about all your PCI cards rolling over the screen.

Also, you're going to have to find out what brand network card you have, so you know which kernel module to load. (Most of the time you just have to tell the kernel what module it has to use, and it'll find the IRQ and IO by itself, I think). A list of modules can be found in the Ethernet-HOWTO.

Hope this helps...
