[comp.sys.ibm.pc.hardware] What do these setup options mean?

I've just gotten a 486 and in looking at the values in the extended CMOS setup
I'm not quite sure what some of them are.  I hope some kind and knowledgeable
soul out there will enlighten me as to what they mean and what values they
should typically have for a 25 MHz 486 motherboard.  The documentation I got
with the machine mentions what some of the settings should be but not what
is actually being set.

So here are the ones I'm not sure of.

Scratch RAM option:  1 or 0
Relocate option:     Enabled or Disabled
CPU Clock:	     CLKIN or ICLK
ICLK:		     CLKIN/3 or CLKIN/4
ATCLK stretch:	     Enabled or Disabled
Fast Gate A20:	     Enabled or Disabled
Cache Range:	     "16 M Cacheable area" is the default value

Thanks!
