cisco 877 ios upgrade

Hi All

Bit of a basic question but i cant find an idiot guide or this.

How do you do an IOS upgrade on the 877 ?

There is no boot command that i can find to tell it where to

boot from.

I will have to delete the previous IOS before i can put the new one

in - do i just do that and it just uses the IOS in the flash ?

Any help appreciated as i dont want to end up in rommon

The 877 is limited on flash so it can only hold a single IOS image in most cases.  As you said, you will need to delete the existing image in order to store the new.  I tend to configure the boot system variable out of habit but the router should load the new image by default.
