I have used coreboot before, but I got a laptop with a weird chip layout that is going to be difficult to coreboot. I found a few workarounds, but I am having trouble understanding them. Would anybody here be willing to help?

Coreboot is hell. I have a few years of college in some Computer fields and I won't touch it.

The first time around I tried building myself and wasn't able to produce a working image, so I did it using a prebuilt rom (skulls) and had no issues. I think I would have a bit more luck now.
>>16609
Thanks. Basically the issue is that there are two bios chips (1 4MB containing bios and 1 8MB containing gbe, fd, and intel me), but only the 8MB chip is accessible. One of the workarounds involved changing the chip layout in the flash descriptor to contain the bios in the 8MB chip, something like this https://ch1p.io/coreboot-t530-one-chip/

The other solution, which I didn't fully understand was this https://doc.coreboot.org/mainboard/lenovo/w530.html

The third solution, which I came to by myself, was to extract blobs, reduce ME, and unlock ifd on the accessible 8MB chip, build and spilt the coreboot rom, flash to 8MB chip, then internally flash to the 4MB chip using a USB with 1vyrain.

I ultimately decided to go with 1vyrain, which isn't full on coreboot, but it allows me to do a soft-disable of the ME and implement other custom bios features while retaining the ability to boot UEFI or legacy (I was planning on going with UEFI via tianocore, but I prefer to retain the ability to do both using 1vyrain). I still might open up the computer and run me_cleaner on the bottom chip, but I have not decided yet. I think I understand the process that would go into that, but I am not entirely sure.

I've only corebooted systems or motherboards by following clear + defined instruction tutorials for that system or motherboard tbh.

If there are no tutorials for your specific system or you're coming to solutions by yourself then you're a couple of levels beyond me.


If there's anyone else reading this interested in trying coreboot you're in luck. A massive number of cheap chromebook models became coreboot compatible in the last few months. They can be found for $40 or less secondhand, schools have millions of them. It's extremely simple to wipe chromOS off them, flash coreboot as the new bios, and install whatever distro or OS you want.

They are amazing, Cheap, rugged little hacking terminals. Now with coreboot. What's not to like?

Nobody else surprised at this? Coreboot devices cheap and available everywhere. People used to fantasize about this a couple of years ago.

Just got a $10 usb c to hdmi adapter for my $40 2019 (ex-educational stock) chromebook that's now running latest coreboot and fedora silverblue. It's got 2 usb c and a usb 3 port. yoga hinge and touchscreen too. It's also rugged af, I would honestly be happier throwing it in a rucksack than a thinkpad somehow.
Pretty cozy sitting back on a hot couch in the evenings with a wireless keyboard watching it play HD x265 on the big screen like a champ.
Painless install too compared to corebooting thinkpads.

Nah I meant because it actually seems more rugged than a thinkpad, crazy as that seems. These things are designed for kids in school. They are so solid.

Doesn't having one of these with the latest coreboot and a secure OS almost solve all the mobile security and privacy issues that exist with cellphones?

I can't understand how people are so wild about corebooting thinkpads for ultimate security but there doesn't seem to be much interest in almost free chromebooks with the same functionality and an easier install.

Sounds good, maybe this'll be my next laptop purchase. I haven't been following stuff on chromebooks, how does it perform? Could you play something like 30fps HL2 on it?
>Doesn't having one of these with the latest coreboot and a secure OS almost solve all the mobile security and privacy issues that exist with cellphones?
Mostly yeah, it's the metadata that does the work. Plus I remember some thread a few months back where someone was advertising some mobile phone equivelant of corebooting if my memory is correct.
>I can't understand how people are so wild about corebooting thinkpads for ultimate security but there doesn't seem to be much interest in almost free chromebooks with the same functionality and an easier install.
Plenty of people pretend to be tech jesuses but in reality they really are just follow trends, it's like with many other things like cars where one of the models gets a cult following despite there being a much better alternative.

Don't think i mentioned specs anon. Performance will depend on the specs of whatever model you get. In the last few months hundreds more models have become coreboot compatible so it's looking good.
>Mostly yeah, it's the metadata that does the work.
With this setup you control almost all the metadata, compared to a phone.
>I remember some thread a few months back where someone was advertising some mobile phone equivelant of corebooting if my memory is correct.
Now that sounds interesting. I can't find anything on it, link?

Yeah well I guess, it's easier as wellbbut you can also technically control metadata on your phone by using it in a really conservative way. Like using a completely different writing style etc. with the whole thing wrapped in foil.

A nightmare because of Chromeos? I never used it. If the screen is broken you can probably still flash coreboot onto the firmware headlessly, install your distro, and connect it to an external monitor as a media pc or whatever.
Another use is to install a router OS like pfsense an use it headlessly as a router.
>Worth repairing?
Depends on the specs of the device and the cost of repair. List model or specs if you like. I would usually say that shit is worth repairing.
Guys, I'm coming at this from a certain position. I had the gear lust. I was spending time obsessing about shitty gpd handhelds for $600 that didn't even have coreboot. Dreaming about boutique phones with mechanical pop out keyboards for $700. Then I fucking find out that I can install coreboot and every distro on an indestructible military grade (educational grade) 10 inch yoga touch screen netbook that I got second hand for $10? My mind is blown. Yours should be too.

i will have to dig it out but the main thing i remember having issues with was the shitty hardware. i understand it was a cheap laptop (it got delivered to me on accident because the ex-tennant there was running scams but he went to jail and i moved in) but the keyboard was trash and in a non-standard format iirc and maybe even had only a left click button, not a left and right.

Many chromebooks can be corebooted without an external device, by just disabling the write protection depending on the model.

Yes it is less free because Coreboot includes binary blobs (non free parts) while Libreboot does not. Libreboot also completely removes the Intel ME while coreboot only "cleans" or disables the ME via a program called me_cleaner. me_cleaner leaves parts of the IME code on the chip and the IME actually starts alongside the bootup on Corebooted machines but in theory it has all functionality removed.
