There is no question of "if", only "when" you will need it, like a reboot that needs you to press F1 or something. Attempting to perform this kind of upgrade without that would be very foolish. If it's Dell you can add a DRAC card (used ones are not that expensive), or any other brand name will have something similar. If it's not a brand name you can get pretty close using a Lantronix Spider and a remote power switch. The system board might already have a BMC with some ability for remote access. Fix the remote access problem before trying the 64-bit upgrade. ❧ Brian Mathis
