Today I recieved a in-warranty replacement for my
Diamond Speedstar 24X.  On the card I've noticed a few
changes; mostly there is a new jumper labeled JP5.
(The card is revision 5A)

My detective work has shown that this jumper simply
connects/disconnects the BALE line on the 64-pin part
of the ISA bus.

The question I have is simple:
To those people who own this revision of the Speedstar 24X,
what does the manual claim that this jumper does?

To anyone with an ISA-reference, what is the function of the
BALE line?

On a related note:
Are there any FTP sites which contain a descriptive reference to
the ISA bus?  My motherboard manual has a simple pin-to-signal-name
chart, but that is it.
