BIOS Caching

[Roger]

I ran SiSandra and one of the suggestions was that I should cache the
BIOS. I went into the board "setup", but could not find any reference to
caching the BIOS.
Does someone have an idea where I might find the setting, and secondly,
would the change be worth the effort ?? Thanks

In the bios (each BIOS is different) there should be something called
'System BIOS Cacheable" this can be set to Enabled or Disabled. Having the
BIOS cacheable will only copy your BIOS into your RAM on boot.

Personally I would use this program instead and it doesn't have you alter
your BIOS.

The book "The BIOS Companion" ISBN 0-9681928-0-7 discourages enabling ANY of
the various BIOS cache options, to include Video BIOS, System BIOS, Video
RAM, etc.

SiSoft SANDRA's recommendations are not in line with this info - so, who do
you trust?

It's not a matter of who I trust. If I trusted a specific source, I wouldn't have
asked the question !!!

Video and BIOS cache usage is absolutely safe or the
manufacturers of the motherboards and bios would not let
this feature be used on all the motherboards I have owned
for the last 15 years (at least.) I have it enabled (when
received from manufacturer) on everyone of my systems (4
laptops and 3 desktops currently personally owned and those
I set up at work.) It significantly speeds up the access to
the video bios and system bios and doesn't take a lot of
memory (System RAM) to do so. I can see not putting VRAM
cached into main memory since VRAM is in itself memory
almost exactly like the RAM in your computer. The bios for
both the system and video are slower responding types of
memory that stores information while the system is off.
When the operating system accesses this "read-only" type of
memory (yes it can be changed by flashing it) it will
significantly slow down the system if a lot of access is
made.

Computers with 32-bit operating systems like Windows XP do not use the
system BIOS or the video BIOS at all after booting, except to run 16-bit
programs. So BIOS caching will not affect performance one way or the other.
