Configuraton register settings

Hello forum, been away for a while...work...we all know how that goes.

Question. I am finding a hard time remembering the Configuration Register settings, does anyone know of a list, or has anyone put a list together?

0x00 loads ROM monitor
0x01 Loads ROM
0x02 specifiesa default boot file name

I get lost when it come to the 0x02 range, for example - I believe 0x2102 is used to perform password recovery.

thank you,
Cheers

0x2102 boots the IOS in flash

0x2142 ignores the startup-config in NVRAM to perfom password recovery.

oh gosh...you are so right, then you for catching that Net. Do you know where i can find a list of settings, or are these pretty much the only two i need to know for now?

Thanks.

for the test, you need to know the main values. like 0x2102 0x2101 0x2142

here is an okay whitepaper on it.

How is the CCNP studies coming? Which part are you doing first?

I just started BCMSN. It's actually going really slow. The first two chapters are very deep and dry. All these business/architecture models that are like brand new to me. I'v never worked for a large enterprise so I don't have any personal experiences to base my understanding on. It's all kinda abstract at this point, which makes it pretty difficult to sink in. Slowly but surely I'll wade through it. After the first couple chapters, I think the more interesting technologies and configurations will start.

Good luck to you
