The 22MHz upgrade is for the 500s and 600s. Basically the standard motherboard
is swaped for a 700 motherboard. The clock speed goes to 22 MHz and you
get the entire WE32200 chip set (including 32206 MAU). I believe this upgrade
will not work with 310s and 400s because they use different memory cards
( without ECC like the 500, 600, and 700). The upgrade package include a new
facepate with the designation 3B2/522 or 622 accordingly.
