I have another 2400 with the newer 240mhz and I used to get that message. I don't think that it has anything to do with enabling the card bus as I got the message and the card bus was not enabled on that unit. (it did not have the yellow trace wires) Willie On Apr 11, 2004, at 8:11 AM, Ernesto Forcadilla wrote: Is the disabling of the card bus has anything to do with this loss of Backside L2 cache? How can I restore the 1 MB L2 cache?
