It cannot look at the configuration file when it cannot even load the IOS. It will go to rommon and I do not think it will tell you that flash is bad, but you might get a "magic" number fail or something that might indicate a flash format error of some kind. It will go to rommon.
NO, not necessarily. If the device goes directly to rommon, it just means it had no IOS to boot thus falling into rommon. The hardware could be perfectly fine but with no IOS to boot it will go to rommon.
I agreed w/ Roberto that if the flash failure, the POST still passed. But cannot load the image from flash. You can imagine that the image is crashed, when it is being load from the flash to the DRAM, it can't complete. So the image cannot be used and the router will try to look for another image in the network via TFTP. First of all, if you have basic configuration (e.g. IP address)& TFTP server w/ IOS image, then the TFTP will work, otherwise, if it is a clean config., you cannot download the image from TFTP.
