Global symbol "%options" requires explicit package name at pcData.pl line 19.

That means that you use strict;, but you didn't declare the %options hash variable, typically with my.

What options in %options are possible and how I can/should configure it?

The module documentation should describe what options are available. I took a quick look through Sys::Info and its other modules, but I didn't find anything relevant. You can look for example code usages, for example in the "t" test directories that come with the distribution. You can also look through the source code. If that doesn't help, contact the module author

is there a nicer way to get this informations?

The SEE ALSO section mentions more alternatives than you can shake a stick at.
