For some unknown reason, Linksys decided to underclock the NSLU cpu at
133Mhz (half its spec'ed 266MHz speed). Here's a link on how to restore
the cpu to full speed.

Probably for power consumption or heat production reasons.

 

I had a Athlon XP box I ran at half clock cos its PSU was a piece of s*** and it would crash at any higher speed.
