I've been using Slitaz ( which ain't no sloutch ).
Tried Porteus about a year ago with ( for some reason ) no luck.
Tried again now and it's working great.
I was going to simply boot and run off the USB, but couldn't resist
trying install to HD, and works fine.
This is for offline PC in my laboratory.
1) Runs DATS (woofer tester) with Wine better than Windows
2) Changed Slax .sb extention to .xzm on Minicom and runs fine.
3) Plays mp3's fine.
4) Boots fast.
5) On the USB stick (ext. 2) runs great with persistence.
( One of these days I am going to do a USB only PC ( no HD ))
Thank You !!!!!!!!!!!!!
