Hey, it's a lot easier than back when I first started playing with networking, in the 1990s. Granted, it was normal then to install off a CD, but on the flip side, it was normal to need to get specific drivers for your actual card. We got to know a few reliable cards (Realtek network cards, ET6000 video cards, and such) that would always work with our beloved OS/2, and if anything went wrong, I'd go to my stash and grab one. Otherwise, it was a matter of transfer by floppy disk, or pulling out the LinkWiz cable and moving data through the computers' parallel ports. (Or their serial ports, if we didn't feel like unplugging the ol' noisy. So much slower that way, even though LinkWiz would (ab)use quite a few of the pins for extra data.) These days, the face-palm DOH! moment usually comes from ssh'ing to a box and then ifconfigging the network interface down. Yeah, that one gets annoying.
