Installation on GIGABYTE GA-970A-DS3P mobo

Post by Surefire » 2018/09/21 06:19:59

Hello,

I'm trying to install CentOS 7 on the motherboard listed in the subject from an .iso I burned to disk. I was initially able to complete a minimal installation successfully but, after a power cycle, could not boot into the system. During POST there are usb-related errors which are apparently (and unfortunately) common with this mobo but I can't find a way to troubletshoot what's truly preventing the system from starting.

Any recommendations on where to start would be appreciated.

Thanks!

When you see the grub menu with the list of kernels, hit 'e' to edit the default one, locate the linux16 line for that kernel in the correct kernel stanza in the file and append a space followed by amd_iommu=on to the end of it and then hit Ctrl-x to continue booting.

You may also need to turn on iommu in the BIOS settings.

No luck, unfortunately. There must be other settings that need to be adjusted.

Adding this info in case some other poor, dumb soul lands themselves in this same situation.

BIOS settings required:

Ensure IOMMU is enabled, XHCI handoff is enabled, EHCI handoff is disabled, USB Legacy support is enabled. OS type I have set to Windows8 but have CSM enabled "Compatibility Support Module" so Linux will boot via BIOS emulation instead of UEFI.

This link was super useful: https://gist.github.com/2E0PGS/fdfefb89 ... 1a1c9cb980

Then install the OS in basic graphics mode.

After that, then you can hit 'e' and edit the GRUB file.
