There is a question floating around that says "when the running-config directs the router to do so"... this is utter rubbish, how can the running-config tell the router to do so when there is no IOS?... no IOS means no running-config. To answer your question about when would the IOS held in ROM be used to boot the router?... when the IOS cannot be found by the Bootstrap it will eventually look in the ROM for it. It will look in the default location in the flash memory, if there is no IOS in the flash, then it will try to locate one from a TFTP server. If it still cant find an IOS then it will look in the ROM for a scaled down version of the IOS and load it from there. I hoep this put an end to the other false answers that are floating around.
