815 chipset drivers , fifo and dual fifo

[sciport]

Hello,
We are looking at chipset drivers and
contemplating upgrading.
The question of fifo and dual fifo came up
and I'm not sure what that is regarding
IDE.
We are at fifo right now.
Could someone provide a layman's description
regarding fifo and the benefits?
Thanks in advance for any assistance.

FIFO

Also see named pipe (somtimes referred to as a "fifo").

"In computer programming, FIFO (first-in, first-out) is an approach to handling program work requests from queue or stack so that the oldest request is handled next. LIFO (last-in, first-out) is an approach in which the most recent request is handled next and the oldest request doesn't get handled until it is the only remaining request on the queue (or in the stack). Although LIFO seems "unfair," it may be more efficient. A stack that is handled using LIFO is sometimes referred to as a push-down or push-down pop-up stack or list."
