Jpv was faster and more accurate! Thanks!
I was still reading..... =)

@MadCrow:
Sonnet 1.8 is fast but believe me mdd 1.25 is a little faster..! This because L3 cache inside 1.25 (Sonnet hasn't) and a data bus faster (not so much: 133 mhz vs 166).
Your G4 should be enough for MorphOS since this os needs no monster speed. Why don't you look for a sonnet 1.x too? There are some of them on ebay and are cheaper than a 1.8. And fast.
