The P6.61 BIOS is available to download through the JZelectronics website, but we do not recommend trying as it has not been officially released by ASRock, nor it has been publically announced by the manufacturer.While it may run, it will not be ideal as now all new features of the Zen 3 architecture are supported by the 300-series chipsets. There's also no PCI Express 4.0 support of course.
