In the previous post I talked about my attempt to create a script to automate the kernel patches installation procedure on Slackware (stable) and I reported the quick ‘n’ dirty instructions to run it, with also a video demonstration.

My attention is focused on this specific USB device: Toshiba DVB-T TV tuner P/N PX1211E-1TVD. I got it together with my old laptop in the summer of 2006. Albeit this DVB-T TV tuner comes with a standalone mini antenna, I usually prefer to connect it directly to the TV antenna cable using the adapter. This ...
