What is the difefrence between write-through and write-back
policies for CPU cash in BIOS Setup?

So, having had it set on 'write through' as long as I've been using it, I 
looked it up...

Write-through caches ensure that on each write to the cache, there is a 
corresponding write to the main memory. Therefore, whatever is in main 
memory is what the processor thinks is there.

Write-back caches only write the data from the cache to the memory when the 
space in the cache is required for something else.

Statistically, it appears that reads are much more likely than writes, and 
that read-modify-write is more likely than write once and that's it. The 
snag with the first system is that there is a slow write cycle on *every* 
write, though the data is still in the cache if it is required again in the 
near future. With the second system, the write only occurs after a read 
instruction needs its space and it has to be cleared down.

This suggests that depending on program source, the write-back is generally 
a quicker option. I shall have to try it.

There's always the possibility that the hibernation code doesn't see the 
exact code in memory that should be there...but I can't believe that they 
would have implemented it to save without flushing the cache first.

Write-back: A cache architecture in which data is only written to main memory
when it is forced out of the cache. 
Write-through: A cache architecture in which data is written to main memory at
the same time as it is cached. 

Write-back is faster.

Waterfall Pro and Libretto

Hi all, 

I have just downloaded Waterfall Pro 2.0 and am trying to get it running on
my 110CT.  Waterfall Pro needs to know the model of the mainboard during
its Setup.  Does anyone know what this is for the 110CT?

Thanks,
Martin
