Have Intel disabled PAT from their i865 chipsets?

[Revo]

I was considering buying an Asus P4P800 or an Abit IS7 but I have been hearing that Intel have or are going to disable PAT on their i865 chipsest so that motherboard manufacturers cannot use their cloned PAT feature. Can anyone shed some light on this issue? Also, which board is the best for overclocking, Abit or Asus?

read about it. its a stinking google search. I could tell you everything about it... but then... you could just do the resarch yourself....

Thanks for the tip but, that could be said that for most of the topics in these forums. I always thought forums were for the exchange of opinions. If everyone said "its a stinking google search" then what use are these forums? I have conducted a search on Google and I have established that Intel may have disabled PAT on their i865 chipset but I wanted to understand whether any further developments had been made.

I would just like to suggest to you that in future if nothing positive can be said it is usually better not to reply. One last thing, if you hadn't figured it out, this is also a form of research.

I was out of place... Please accept my apologies...

Basically the deal is that PAT is disabled in 865 chips when the chip can read the apropriate fsb from the bios (or wherever). Asus, and then a few other manufacturers found that the vast majority of 865 chips are indeed capiable of succesfully running the lower latencies and figured a bypass. The bypass is to feed illegal information to the unique part of the chip that disables PAT. Since the FSB it "sees" doesent match anything its supposed to block, it lets it go and Viola. Pat is enabled. This pissed off Intel big time and it made a massive news splash... was it over the summer?

Hope that was of help. I was having a really bad day at work with a project that was going down the toilet and I shouldn't have even let myself near AT... again my apologies
