by José Domingo Torres Montoya 02 Jan '23

02 Jan '23

Hi, thank you in advance for your excellent work on coreboot for chromebook computers, the UEFI version is working well, but now I need a modification to be able to manage ACPI, I need the computer to always be on, and what if it has Loss of current, when the power supply returns to the Computer, turn it on again without having to press the power button If this modification is possible or already exists, tell me the cost for the feature Thank you again in advance and I look forward to your prompt response. -- www.mrfichas.com <http://www.mrwisp.com> García, Nuevo León.

Press ESC for boot menu
by Mahmut Olger 27 Dec '22

Hello, We are using intel atom C3558 denverton_NS platform. This platform is booting with coreboot4.16. Payload of coreboot is Seabios. Openbsd running in our board. Coreboot is booting successfully. I press ESC key when I see "Press ESC for boot menu" print but I can not select boot device. It is booting automatically. I think the keyboard could not be enabled. How can i solve this problem. You can find seabios config file above and coreboot config file. Mahmut ÖLGER Embedded Software Engineer.

LinuxBIOS
by The Original Linux Fan 27 Dec '22

27 Dec '22

Hi all, Many years ago I was tracking the LinuxBIOS project and was very keenly interested in it. Now, it seems that systems have gotten ten times slower to boot. I have an HP Z840 workstation. It is a 56 processor machine and is very slow to boot. I don't have a lot of money and wouldn't want to brick it, but I am interested in attempting to get one machine working with coreboot. Anyway, if anybody has any time for a newbie, I would appreciate any comments. 73, Linuxfan

Cisco Meraki use coreboot in some MX products and will not provide the source code
by Hal Martin 22 Dec '22

22 Dec '22

Hello, Several Cisco Meraki products (MX84, MX250) are using the coreboot bootloader. Meraki are also distributing coreboot builds for these products via their update mechanism. In October 2021, I requested the corresponding coreboot source code for the MX84 from open-source(a)meraki.com. Another individual requested the coreboot source code for the MX250 around the same time. We own the devices in quesiton. To date, Meraki have not provided the source code or provided an explanation as to the delay in providing the source code. The last reply I received was in January, and they have not replied to any of my follow up requests. As coreboot is GPL licensed software, I wanted to inform the coreboot community that I believe Cisco Meraki are not acting in good faith and are, in my opinion, violating the GPL by not providing the coreboot source code upon request. Kind regards, Hal Martin

There was always microcode
by Peter Stuge 20 Dec '22

20 Dec '22

Recommend these great posts with technical detail and history: https://www.righto.com/2020/06/a-look-at-die-of-8086-processor.html https://www.reenigne.org/blog/8086-microcode-disassembled/ https://www.righto.com/2022/11/how-8086-processors-microcode-engine.html If ever there was a textbook example of a temporary solution becoming permanent then 8086 must be it: "Because the iAPX 432 was behind schedule, Intel decided in 1976 that they needed a simple, stop-gap processor to sell until the iAPX 432 was ready. Intel rapidly designed the 8086 as a 16-bit processor somewhat compatible with the 8-bit 8080, released in 1978." 45 years later, https://justine.lol/ape.html says: "Outside phones routers mainframes and cars, the consensus surrounding x86 is so strong, that I'd compare it to the Tower of Babel."

[coreboot - Bug #444] (New) Flaky gitconfig tests are breaking builds
by Martin Roth 20 Dec '22

20 Dec '22

Issue #444 has been reported by Martin Roth. ---------------------------------------- Bug #444: Flaky gitconfig tests are breaking builds https://ticket.coreboot.org/issues/444 * Author: Martin Roth * Status: New * Priority: Normal * Target version: none * Start date: 2022-12-20 ---------------------------------------- The gitconfig tests are failing when they can't delete a directory they created in /tmp, and this is causing builds to fail randomly. Because it's not a part of the test itself, but part of the cleanup, the failure doesn't get captured, and jenkins appears to be failing for no good reason. Someone should figure out what's causing the rm -rf to fail and fix it so that the builders stop failing. -- You have received this notification because you have either subscribed to it, or are involved in it.

Wanted to track this bug outside of the mailing list since that will probably get lost. I've even cross compared to the X250 and everything looks normal. Am I missing a GPIO? Is there something wrong with the PCIE detection? Perhaps a conflict with the wifi which is on the same PCIE root?
