By default, coreboot will not produce a full firmware image, so one must only flash the BIOS region. With a recent enough flashrom (v1.1 onwards), it's just a matter of adding the `--ifd -i bios` arguments when flashing coreboot. Moreover, the R500 does not use the Intel GbE controller inside the southbridge, but a Broadcom PCIe NIC. Its MAC address does not reside in the flash chip, so it is not easy to change.

[coreboot] Re: Lenovo R500
It's a bit not obvious, but by searching at ./coreboot/src/mainboard/lenovo$ find . -type f -print0 | xargs -0 grep -n "R500" - I could see that R500 is a variant of Thinkpad T400: i.e. " ./t400/Kconfig.name:10:config BOARD_LENOVO_R500 " . Since this board_status table mentions each board type once, only T400 appears there. So your R500 is supported by coreboot, almost certainly blobless. coreboot's installation is identical to libreboot: you simply flash a compiled BIOS image. Tool to change a mac address: I haven't checked if it could be found in ./coreboot/util/ - but almost certainly a libreboot's tool should be compatible with coreboot, and maybe libreboot project took this tool from somewhere else where there's an even newer version On Tue, Jun 16, 2020 at 11:41 AM trabajo3 via coreboot wrote: > > Hello!, I wantt to know if the Lenovo R500 has coreboot support without any > blobs > https://phoronix.com/scan.php?page=news_item=Coreboot-4.10-Released > Here it says that is supported > but > https://coreboot.org/status/board-status.html > doesnt appear > and in the tree also no > > Another question is if there is any tool like in the libreboot proyect to > change mac address and if there is any complete video tutorial to install > libreboot, because in youtube there are full videos about libreboot but for > coreboot i didnt find anyone with good explanation. > Thanks for ur time! > Best Regards > > > Sent with ProtonMail Secure Email. > > ___ > coreboot mailing list -- coreboot@coreboot.org > To unsubscribe send an email to coreboot-le...@coreboot.org ___ coreboot mailing list -- coreboot@coreboot.org To unsubscribe send an email to coreboot-le...@coreboot.org
