This is a gigabyte mobo not msi, this is the f21 bios from january 2017
https://www.tonymacx86.com/media/img_3244.188126/fullI can not find anything about pci inside, can i boot to uefi ? I m pretty lost, i can flash it to f22 but i m pretty sure it won t change anything
I don t know if it can help anybody to find a solution but here are the specs
1. 1 x PCI Express x16 slot, running at x16 (PCIEX16)
* For optimum performance, if only one PCI Express graphics card is to be installed, be sure to install it in the PCIEX16 slot.
2. 1 x PCI Express x16 slot, running at x8 (PCIEX8)
* The PCIEX8 slot shares bandwidth with the PCIEX16 slot. When the PCIEX8 slot is populated, the PCIEX16 slot will operate at up to x8 mode.
3. 1 x PCI Express x16 slot, running at x4 (PCIEX4)
* The PCIEX4 slot shares bandwidth with the M2H_32G connector. The PCIEX4 slot will become unavailable when an SSD is installed in the M2H_32G connector.
4. 4 x PCI Express x1 slots
(All of the PCI Express slots conform to PCI Express 3.0 standard.)
