i5 5675c, z97 Killer 3.1, bios 1.30 : no linux

Hello,

I try to install a linux on a second drive with no luck (except with fedora 22) because in bios 1.30, the motherboard doesn't have (yet?) the intel microcode 0x13 (see here: https://bugzilla.kernel.org/show_bug.cgi?id=103351). I wish asrock will release a bios for this motherboard with the corrected microcode from intel for this processor (broadwell). Do i have to contact support for this ? Is there a way to do this (install microcode) by hand in the bios ? Thanks in advance.

Is this microcode update only for Linux compatibility? That seems obvious since you could use Win 10 with your Broadwell processor and the UEFI/BIOS update provided by ASRock.

Is it typical for Intel to have different microcode updates for Linux and Windows? Obviously Intel does not (or cannot) combine them into one microcode release.

Since most ASRock boards do not officially support Linux, that is why you won't find a UEFI/BIOS update with a Linux compatible microcode.

There is no point in waiting for a UEFI update that contains a Linux compatible Intel microcode for Broadwell, since no Linux support is provided for your board. That kind of update will simply not happen, unless the microcode is also compatible and needed for Windows. Simply pointing this out as an FYI, sorry to say.

Nice work modifying the UEFI yourself, the UBU tool is great.

Two warnings or FYI for you:

Microcode is not normally updated in a UEFI/BIOS update, so you should be able to apply future UEFI versions without ruining your microcode change. That is of course if the new version does not have a microcode update as part of its change.

Whenever you change to a new or different UEFI version, ASRock does NOT recommend clearing the UEFI/CMOS immediately after an update. The UEFI will be in a cleared state after any UEFI change, with default values set for all options. You can select the Load UEFI Defaults option in the Exit screen right after an update, although that should not be necessary, but hurts nothing.
