Lenovo L430 is Compatible about 1vyrain HOT 11 CLOSED

Took another look at this, and turns out I was wrong and that the patches are compatible. My error was that the offset for where the 4MB BIOS begins is different, and after double-checking with binwalk I had success creating a modded BIOS.

You can extract your BIOS from the FL1 file with dd if=BIOS.FL1 bs=1 of=4MB skip=4325840 count=4194304, then patch it with UEFIPatch using this documentation for all the non whitelist patches.

For the whitelist patches, the L430 has slightly different offsets. Add these patches in addition to whichever other ones you want:

Once you've created your custom BIOS, just run 1vyrain to unlock your BIOS region (let it run and exit after telling you it is compatible - at this point your BIOS region is already unlocked), then flash your file with flashrom.

Great to hear! I'll investigate some more and see if the existing patches work on the BIOS.

Flashsize seems incorrect though. You sure it's 80 and not 8?

from 1vyrain.

Yeah, ran it again to make sure and got a flash size of 80 M. Gonna attach a picture of the result just in case I'm misinterpreting something though

Interesting. I'll take a look, maybe I messed up with printing it.

Your laptop is def compatible though so I'll take a deeper look.

from 1vyrain.

Good to know!
If you need the laptop for any reason, I'll be happy to ship this one over if needed.

@dte102 It would be highly appreciated if you ran flashrom -p internal:laptop=force_I_want_a_brick --ifd -i fd -r L430_ifd.rom and uploaded the L430_ifd.rom somewhere. You should be able to run this from a regular linux install with the iomem=relaxed kernel option, or the 1vyrain usb. :D

@digmorepaka Here's a zip of the rom file I got from running the command on the L430.

@dte102 wonderful, Thank you!

from 1vyrain.

Looked into the BIOS patches, and unfortunately none of them seem compatible with the L430, either the new BIOS or the older revisions. It is 100% doable for sure, but unfortunately the existing patches that we have seem to only work on the main line of ThinkPad products (T/X/W). I don't foresee having time to explore new patches by myself, so I apologize in advance; but if we find a better way to generate patches or eventually come back around to this, I will let you know.

from 1vyrain.

Gotcha, that's fine since we know that it's at least compatible and that at some point the L430 might get support. Thanks for looking into it!

(See #87 for further L430 discussion)

In addition to the patches above, one more is required:

because there's one more condition right after C8390E75620F
