I'd say you got it pretty well exactly right!...Did I get it or did I mess it all up (again)?
A lot of the terms in what you'd think would be a precise and logical field are ambiguous or even misleading; for example CMOS stands for Complementary Metal Oxide Semiconductors, an entire family of ICs and other semiconductors characterized by its extremely low power requirements (and thus ideal for battery powered uses), but in the PC world it refers to the chip holding the system's configuration (or the configuration itself); mind you, in even newer systems that info is actually stored in flash RAM, but of course it's still referred to as 'the CMOS'. See:
http://en.wikipedia.org/wiki/Nonvolatile_BIOS_memory
When 'configuring a BIOS' you are using a program in the BIOS ROM to change the system configuration in the Non-volatile RAM that the BIOS uses to do its thing. When the OS sends a command to the BIOS (e.g. read a disk sector on drive 0), the BIOS looks into the configuration RAM (or the PC/XT dip switches) to see what type of disk that is (or if it even exists) and handles the request accordingly.
No offence intended by the dyslexia remark; my typing seems to be getting more and more dyslexic as I get older, but fortunately I can still catch most of it when I re-read what I typed... yeah, pretty funny sometimes ;-)
