WHat model HP computer? (e.g., A6300F, etc.) There is a way, though
tricky, to get both the system specs and full motherboard info off
HP's website. The issue may concern the chipset that's used. If you
followup with the model number I can look it up and reply with the
data.

Depends on how you've setup your system (partitions, etc.). Can you
post the output of a "df" (from a terminal window)?
