Re: [coreboot] booting from msata on t420/how to change boot order
Hi Marcus, I have a running T420 with coreboot running from an msata ssd. Works like a charm. However, I have grub as payload. Do you intend to run windows, or why do you want seabios? Hope that helps. Cheers, Ari signature.asc Description: OpenPGP digital signature -- coreboot mailing list: coreboot@coreboot.org https://mail.coreboot.org/mailman/listinfo/coreboot

Re: [coreboot] Thinkpad T420 Thermal Management
Hi > Anybody tested Thinkpad T420's thermal management and fan speed control? I'm running one albeit with an i7-3740qm - which is too much thermal load, runs up to 2.9 GHz for me reaching 93°C (70K to ambient) with fan set to disengaged, normal auto fan control works and allows up to 2.5 GHz. with that CPU RAPL does not work, thermald does but out-of-the-box settings gives me less performance than with fix limits, and I'm sure as hell not going to configure something with an xml config file. used to have a 2720m which worked without any issues AFAIR, but the 3740qm effectively gives me double the cores that are a little faster. anything else you want to know?

Re: [coreboot] t420 CPU Upgrade
Hi chub, I have a 3740qm in mine, runs fine with the minor constraint that it isn't completely full-load-stable - apparently something decides to shutdown the machine at 100°C core temp before the cpu reduces boost from 3.5 GHz - happens to me in the third run of a kernel build with make -j8. regards, arian On 27.08.2016 06:08, c...@tuta.io wrote: > https://www.coreboot.org/Board:lenovo/t420 > > How stable is the i7-3720qm CPU Upgrade in the t420?

Re: [coreboot] How to use properly the GRUB payload?
Hi Ioannis, I ran into a quite similar problem - I think the wikipage needs quite some overhaul. anyway: I also have grub2 as coreboot payload. It seems to have a memdisk, but I don't know how to change this. There is a workaround: a grub.cfg gets into that memdisk, which sources (cbfsdisk)/etc/grub.cfg - find for that in the coreboot tree. the solution then is to add a grub.cfg (and other files, like additional grub modules, background image, ...) to cbfs (in coreboot tree root): ./build/util/cbfstool/cbfstool build/coreboot.rom add -f mygrub.cfg -n etc/grub.cfg -t raw actually it's a good idea _not to_ put etc/grub.cfg at first - if you have errors in that you may end up softbricking your device. put it somewhere else and source it from the grub command line. regards, Arian On 24.07.2016 20:43, Ioannis Koutras wrote: > Hello John, > > And thanks for replying.

[coreboot] grub2 payload: not including additional modules
Hi all, I try to build coreboot-4.4 with grub2 payload for a thinkpad T420. Which largely works, but I'm unable to get it to build coreboot.rom with extra grub modules, in particular cryptodisk.mod relevant .config: > arian@jira:coreboot-4.4$ grep GRUB .config > CONFIG_PAYLOAD_GRUB2=y > CONFIG_PAYLOAD_FILE="payloads/external/GRUB2/grub2/build/default_payload.elf" > CONFIG_GRUB2_MASTER=y > CONFIG_GRUB2_EXTRA_MODULES="luks cryptodisk crypto pbkdf2 extcmd procfs > archelp" (I put in the additional modules since I thought it's maybe dependency resolution, but of these crypt, pbkdf2, procfs and archelp make their way into the image, while luks, cryptodisk, and extcmd don't. There is no error. I think this is a coreboot problem since the modules themselves are getting built, I can find them in payloads/external/GRUB2/grub2/build/grub-core/cryptodisk.mod Could anyone help?

Hi Huno, not terribly knowledgeable and speaking from T420-experience > I've read and used the blobs from the "damaged" custom BIOS. I'm not sure if > this can affect the functionality of Coreboot. Apparently, it does not. If you had damaged the ME firmware, you would not reach coreboot or any other firmware - the blob is signed If you had damaged the NIC firmware, ethernet would probably be broken, so that's clearly defined. > /(Let me know if anyone of you need details/help about/with the HW flashing > in this type of chip (MX25L6406E/MX25L6408E)). refining the wiki would be a good thing to do > *3.1) RAM speed:* > --- > *=> So, if I'm understanding it correctly, current 667 Mhz is not the maximum > ***speed *supported. > Any idea on how I can get higher speeds?* That's RAM _clock_ not data rate which is double the clock rate (-> DDR) - you're not any worse off than with the original firmware. signature.asc Description: OpenPGP digital signature -- coreboot mailing list: coreboot@coreboot.org https://www.coreboot.org/mailman/listinfo/coreboot
