The reason it was added is PAT PDC only initializes boot and console devices. The RESET_DUMP_DEVs was added to initialize a list of devices so IODC could be used in the HPUX dump path. > where dumpdev is the list of all "struct device_path". > It would be really interresting if someone is able to > find the "parisc 2.0 I/O firmware" doc, it would gain > a lot's of time to poor little programmers like me. Best is to scrounge through HPUX source code. With docs, it's often difficult to know *where* to find the right info. grant
