At which stage do you want to enables these ports? in the OS? or during boot? if the latter, which payload do you use? Zheng: I want to enable these display port during boot. The payload is SeaBIOS. Zheng From: Nico Huber Sent: Saturday,

Re: [coreboot] Lenovo X220t variants with SMD-Flash-ROMs

Do we have any idea what exactly they do to update the firmware internally? The wiki says once coreboot is flashed you can flash it internally. I suppose this means the blockade protecting the flash can be switched of somehow, as the vendor's have to do it to install firmware-updates. Am

Re: [coreboot] Lenovo X220t variants with SMD-Flash-ROMs

Hi Philipp, It is just a wson-8 flash rom, whose soldering plates are compatible with those for soic-8 chips, often found on thinkpads produced when 8MiB soic-8 chip are hardly available. The common way to deal with wson-8 chips is to blow it off with hot air blower, suck up its content, and

Re: [coreboot] About Paging, Realmode and what is going on

in the akaros virtual machine code, we set up a simple 1:1 map and start linux at the 64-bit entry point, at which point it builds its own page tables. So entering a payload in long mode is certainly possible and IMHO ought to be the standard on amd64 -- not that anyone cares what I think anyway

Re: [coreboot] Lenovo X1 carbon 3460 Screen stays black

Howdy, In your config file you have: # CONFIG_VGA_BIOS is not set in coreboot, which will mean that coreboot doesn't setup the display, but in your SeaBIOS config you have: CONFIG_SEABIOS_VGA_COREBOOT=y which will try to reuse whatever coreboot has setup. So as you might understand, this
