IDEDirCache
This sets the amount of computer memory which will be used to remember what
i
s on a hard disc. The default value is 8K. If you have plenty of memory in your
computer

*configure IDEDircache 16K will improve disc access speeds.
Drive
The command *configure Drive 4 will cause drive 4 to be selected when
you turn your computer on. This will be your IDE hard disc, assuming you have set
I DEFS to be the configured filing system.
HardDiscs
The command *configure HardDiscs 0 tells the computer that you have no
ADFS hard discs fitted. Use this if you are fitting an IDE hard disc as a replacement.
I DEFS operating system commands
A list of all the IDEFS commands can be seen if you give the operating system
command *Help IDEFS .

*IDEFS
This command makes IDEFS the current filing system, as has already been
mentioned. You will rarely need to use it if IDEFS is your configured filing system.
*IDEProtect
This command protects an IDE hard disc from being written to, and is effective
until the computer is next reset.
*IDEUnprotect
This command reverses the effect of *IDEProtect .
*IDEPowerSave
Some IDE hard discs can be told to stop spinning in order to save power if they
have not been accessed for a given length of time (the 'timeout period'). This
command is followed by a number in the range 0 to 255, which sets the timeout
period in multiples of five seconds. *IDEPowerSave 6 sets the timeout period
to 30 seconds, while *IDEPowerSave 0 turns the feature off.
Some hard discs will ignore settings below a certain value, such as 12 (for 60
seconds). The command will have no effect on discs which do not support power
saving.
