Since updating my Alienware 17 R4 to BIOS version 1.18.0 (16 May 2022), I getting followed error in my Linux =
DMAR: [Firmware Bug]: No firmware reserved region can cover this RMRR [0x000000003b800000-0x000000003fffffff], contact BIOS vendor for fixes DMAR: [Firmware Bug]: Your BIOS is broken; bad RMRR [0x000000003b800000-0x000000003fffffff]
It makes boot time up to 2 minutes more than on version 1.17.0.
Question to Dell's employees, what you trying to do?
Hi @bacaTM welcome to this free user-to-user Alienware laptop discussion forum.
This forum is not Dell Support and the old Alienware 17 R4 has no Dell warranty.
The Alienware 17 R4 Drivers & Downloads are specifically for Windows 10, 64-bit, there is no support for Linux. BIOS versions should not be updated if there are no additional features for your system. BIOS version 1.18.0 was released on 16 May 2022. Alienware 15 R3/17 R4 System BIOS | Driver Details | Dell US. Perhaps installing BIOS version 1.18.0 again might fix your Linux boot time problem, or make it worse? There is no option to install an Old BIOS version. Perhaps waiting for the next BIOS version update is prudent?

Fortunately, after removing a few parts from this laptop, everything is fine with it. Of course except BIOS. "Problem" is not only with this one BIOS installed on exactly this laptop. Is the same "problem" with the rest devices produced by dell too. From functional point of view problem is what this BIOS trying to do in specific configurations and what it doing in the rest of configurations.
Personally I think that dell can be good example/side in the case.
BTW, it is good that you mentioned warranty here
Regards
PS. If it is not dell's forum at dell.com domain so where I should will send technical report about this BIOS? Everywhere?
