AGP/PCI locking system

Why P4 motherboards have this AGP/PCI locking system while Athlon XP motherbaords don't have? Is it because the motherboard manufacturers don't want to implement it or it's VIA/SIS/AMD chipset (for AMD cpu) limitation?
Thanks
 
I don't think that they don't want to do it, they just haven't gotten around to it. The P4 chipsets for new P4's were designed after the AMD XP ones (KT266/266A uses one of the newest AMD chipset designs; the KT333 is just an updated KT266A) ... The i845/i850 chipsets are a bit more recent. I could be wrong however, but I don't think it is by any means intentional by motherboard manufacturers, and perhaps it isn't possible to do on AMD XP's right now...
 
no its not in the chipsets - its in the clock gens and they have to be hardcoded for it.
for you to have the option in the bios, it would also need to be softcoded.

its possible thats it is there - but not softcoded for it.

So what you mean is that the motherboard manufacturers don't want to implement it ?
 
I think Asus and MSI are more on INTEL side because if u see, their motherboard for AMD CPU have only 5 PCI slots while for INTEL CPU they implement 6 PCI slots 🙂 except EPOX 🙂

yep - its the same story on the i845 boards that dont have a 3:4 ratio. its there but its not softcoded.
