Is the PCI slot of Z77 motherboard native?

We all know that B75 motherboard supports native PCI function, but chipset Z77 doesn't, so why do we see that Z77 motherboard has PCI slot on some manufacturers' motherboards?

The reason is that ASMEDIA's ASM 1083 PCI bandwidth conversion chip is added. ASMEDIA's ASM 1083 PCI bandwidth conversion chip makes Z77 not supported by native PCI devices. Asmedia ASM 1083 chip can switch the bandwidth of PCI-E to PCI slot, thus supporting PCI.

If users need a PCI slot for business purposes, or suggest buying a B75 motherboard that supports native PCI, the non-native use will be affected more or less, just as the non-native SATA3.0 interface cannot be used as a boot disk, so the performance will also be lost. ;
