Anyone familiar with the HP VEi7 ... what processors are supported?

[Kwad Guy]

I have a HP VEi7 desktop computer. The one I have came with a
Celeron processor. However, I have seen VEi7 machines advertised
with Pentium processors. Does anyone know if the motherboard in this
machine supports both Celeron and Pentium (flip-chip version,
obviously)?

Also, does anyone know which (how fast) processors are supported
on this motherboard using the most recent BIOS flash from the
HP site (middle of last year)?

I can't find the answers to these questions on the HP site (no
surprise...)
