what part of the configuration-register identifies location ios?? 1

[Prizmm]

I have run into this question a few times and the only answer i can find is "the lowest 4 bits" is this correct? If so, can anyone explain? Again, here is the questions:

"What part of the configuration-register identifies the location of the IOS?"

Thanks

Bootstrap code always checks the low order first 4 bits of the config register to find out how to boot the router.

It is the lowest 4 bits.

so if it is ox101, what are the lower 4 bits? Thanks

Remember this is written in hex, so the 101 in 0x101
are hex-numbers.
The last 1 in 0x101 is the hex-number 1 that
translates to binary 0001, this are the 4 last bits.
So if you want to write the whole 0x101 in hex it
would be something like 0x 0001 0000 0001
Hope I explained this so that it's possible for you to understand it ;-)
