UEFI BIOS brings faster boot speed and new hardware support. BUT, as your know, I have an old GA-P67A-UD3-B3 mb, gigabyte website gives UEFI bios as version U1d. I found the UEFI bios have a bug: the pcie 4x will work down to 1x with the UEFI bios(it works 4x with F9 legacy bios) (NOTE: my all pcie 1x are empty)And a small note:
I installed one of these cards:
“dodocool PCI-E Express Card with USB 3.1 and Type-C Ports 15-Pin ConnectorSuperSpeed Gen II (10 Gbps) for Windows 7 / 8 / 8.1 / 10 Linux Kernal”
Purchased from Amazon: https://www.amazon.com/gp/product/B01C59TB0I/?tag=tonymacx86com-20
The speed of the Type C port is really good however on this old system, old BIOS the card is not fully initialized until the OS is up and running; meaning I could not boot an SSD that was attached via SATA to Type C adapter. Where as on current UEFI tech system the same SSD set up was bootable and the speed was very good.
May have any advice about this problem?
