I can actually see the data on the > SMbus happening but I don't ever seem to get a result back. ah, richard, it just occurred to me. A lot of the spd code starts the op, and waits for the 'active' bit to go to 0 in the status. If the CPU is too fast, it will sample the 'active' bit before the smbus hardware starts to do anything. Then you read back bad data. As I found on some chipsets, the CPU can be too fast, and it should: 1. start op 2. wait for 'smbus active' indicator to go to 1 3. wait for 'smbus active' indicator to go to 0 is this by any chance your problem? ron _______________________________________________ Linuxbios mailing list Linuxbios@clustermatic.org http://www.clustermatic.org/mailman/listinfo/linuxbios
