apparently Gigabyte has/had some strange ideas about UEFI.
sadly i didn't know this and couldn't shop other than through
the phone line talking to someone so i had to rely upon them
selecting a motherboard for me. don't really want to sent it
back either.
I have two Gigabyte m/b's I've been using for some time and only
recently got things, sort of, figured out. Here are a few suggestions
and I hope they work for your m/b:
- disablbe IOMMU support (more on this in a moment)
- specify "UEFI and Legacy" for "Boot Mode Selection"
- specify "Legacy first" for "Storage Boot Option Control"
- specify "Legacy OPROM" for "Other PCI Device ROM Priority"
- though this will depend on your installed hardware
- I have switched "SATA mode selection" to "AHCI" instead of "IDE"
- your choice
- If you decide to _not_ use EFI, __ALWAYS_ go into the boot menu to
select the BIOS mode boot for the USB stick you are using.
- Once in the Debian installer boot menu:
- in BIOS mode press the "TAB" key (I __SO__ wish I had found
out about this months ago)
- add the following to the "linux" command line:
iommu=soft
- if you are going to create a raid array (mine is
raid5) also add this to the "linux" line:
rootdelay=10
- press the <ENTER> key
- if you choose EFI boot mode, edit the install command line as
above
Until I started using the above I couldn't get any of the USB ports to
function and the raid array to come up properly.
YMMV.
