Hello!, I wantt to know if the Lenovo R500 has coreboot support without any blobs https://phoronix.com/scan.php?page=news_item&px=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

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

Yes, this is a known problem of board status.

This is untrue. 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.
In any case, there's documentation in coreboot: https://doc.coreboot.org/mainboard/lenovo/montevina_series.html
