Coreboot Lands Updated ME_Cleaner, Purism TPM & Other Updates

As azdaha says, it was added. It's a Lenovo X131e that came with 4GB. I replaced the memory and the wireless as part of the conversion.

As a chromebook, it would only see 8GB of the 12GB which is what Intel claims for the CPU itself. So, that was clearly a software limitation in place rather than a true hardware limitation. So, I'm not sure if you could get a 'chromebook' with 12GB based off of this platform. There were other firmware modification options that kept support for the chromebook. It's possible that some of them would remove the DRAM size limitation. I did not explore those options as I had no interest in keeping the chromebook functionality around.

Interesting.

Thanks.

I wasn't aware there were Chromebooks where the RAM wasn't soldered on.

I'm unsure of what CPU that device actually has. According to specs online it can have a Celeron 1007U which in hardware supports up to 32GB of RAM https://ark.intel.com/products/72061...Cache-1_50-GHz

Or an i3 that supports 16GB https://ark.intel.com/products/59798...Cache-1_40-GHz

So the 8GB limitation sounds like an artificial bullshit limitation. It's VERY common for laptop manufacturers to place artificial ram size limitations in their firmware. I've seen piles of HP laptops where the processor was supposed to see 16 or even 32GB of RAM and the laptop would refuse to boot (or see) more than 8 or 16 GB.

In general, the ARK site does not lie, it lists the actual hardware limitation of the processor's RAM controller.

How is performance compared to default firmware? Any regressions?

No real way to tell as the default firmware won't boot linux, just chromeos.

You're right, it was the Lenovo page that said 8GB was the limit--which seemed to be accurate. The ARK did show 32GB, so I had hope that with a clean BIOS, it might support more than 8. Fortunately, it did.
