This one in particular is on the MBX860 board. It relocates the I2C parameter ram when SCC1 is used for Ethernet. I have since become smarter, and I am now making Linux install it's own microcode patches. This is necessary because drivers have to be modified to know such patches exist, as the programming interface physically and logically changes. It is now appropriate to reset the CPM and remove all existing configurations. > and then on a reset or when a NMI exception is generated, does that > mean that no reset of the CPM must ever be done. I don't remember the effect of external resets on the CPM. I am travelling right now and don't have the book handy. -- Dan ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
