# Keyword types

The keywords for a CG 6565E board describe that board's configuration. Some keywords are read/write; others are read-only:

Keyword type | Description
Read/write (editable) | Determines how the board is configured when it starts up. Changes to these keywords become effective after the board is rebooted.
Read-only (informational) | Indicates the board's current configuration. Read-only keywords cannot be modified.

A keyword has the general syntax:

keyword = value

Keywords are not case sensitive except where operating system conventions prevail (for example, file names under UNIX). All values are strings or strings that represent integers:

- Integer keywords require a fixed range of legal numeric values.

- String keywords either require a fixed set of legal values or accept any string.
