Got the F5A bios for this board and set to hybrid.
Now all of a sudden there is advanced chipset in the bios menu that was not there before.
In this menu are:PCIE_16_1 Gen2 speed mode
PCIE_8_1 Gen2 speed mode
PCIE_1 GEN2 speed mode
PCIE_2 GEN2 speed mode
GFX7 GEN2 speed mode
GFX9 GEN2 speed mode
Choices are: auto, disabled,
SW switch,
HW switch
another setting (sub menu)is PCIE Configeration
and SB700 SPREAD SPECTRUM

Weird thing is that yesterday the advanced chipset entry was not there.
