P3 Firmware Alert

We recently discovered that P3s shipped in approximately the first half of December, 2010, may have been loaded with an early engineering version of our firmware boot loader. This has no affect at all on the general operation of your P3, but it does look unusual during a firmware upgrade.   Click here to read a .pdf file on how to determine if your P3 is affected and what to do about it.
