Re: [Trisquel-users] extract rar file freely?

Don't trust 3rd-party BIOS modifications. I don't see it necessary to remove  
the white-list of X61/T61/R61. There are two powerful Atheros cards  
authorized by Lenovo's original BIOS, namely AR5424 and AR5418. Be sure to  
purchase one with FRU ID (i.e. original Lenovo part) and you won't be blocked  
by the white-list.

To unpack proprietary RAR packages, I don't find anything better (freer) than  
"unar". Just download the latest version from Debian's testing/unstable  
repository, as long as your system meets the dependencies.
