For the XM, the Numonyx part is at 165Mhz, and the Micron part is at 200Mhz. I'm using u-boot with a configuration header, and there I have set the new CTRLA, CTRLB and RFR values (and I did compare the values with the Micron data sheet; apart from the TCKE value they are all identical). But are you saying that the values set by the boot loader are preserved by the kernel? (In that case I wonder what the sdram-micron header file is for :) Thanks, Orjan -- Orjan Friberg FlatFrog Laboratories AB
