I remember when I added something similar to the lapic series that both of my C2D systems (Merom + Woodcrest) reported that they didn't support the feature in the HW. Since those were fairly new, which ones *do* support this (out of curiosity), or is there a microcode update floating around out there ;). -Greg ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
