Hi alwaysasking!

Personally, I would recommend Libranet 2.7 Classic Free Edition. Redhat 7.3 is not bad (in fact, it's the best one from Redhat in my humble opinion). But you might be having difficulties in getting your hardware well supported with an older kernel.
You can download Libranet
here. A review of Libranet is found here

The installation, boot loader and stuff is pretty simple nowadays, specially with a distribution as Libranet. You might want to check
Linux homepage for general info and intro into the amazing World of freedom that Linux offers...
