Device6 of Intel 875P?

The newest 82875P MCH has 4 devices (device 0,1,3,6).

https://developer.intel.com/design/chipsets/datashts/25252501.pdf


But when I scan pci bus, there is no device6. only device0,1,3
(Device0 = DRAM Controller, Device1=AGP Bridge, Device3=CSA Bridge)

How can I access device6(Overflow Configuration Register adhered to Device0)?

82865G/P/PE has the same problem.

Thanks in advance...

Reply by myself,

Dev6 can be enabled by Dev0.

The bit1 of register F4h enables Dev6.

It's the hidden register.

Bad Intel...

You can use selftest to find the device6!
The selftest software is downloaded from Intel!
Why not use AMD products???
