This will be a problem in notebooks due to space considerations, so i expect that a clock upgrade will also be in the works. PCI was specified before there was abundant silicon that would support 66MHz, but AGP has opened that door. jan lambert ----------------------------------------------------------- [log in to unmask] ----------------------------------------------------------- Do you want to signoff PCBUILD or just change to Digest mode - visit our web site: http://nospin.com/pc/pcbuild.html
