X220 BIOS 1.44 (Spectre patch)

[Puppy]

https://support.lenovo.com/cz/cs/downloads/ds018807

Code: Select all

<1.4-1.24>
 UEFI: 1.44 / ECP: 1.24
- [Important] Enhancement to address CVE-2017-5715.

Any experiences?

and one more question - is there a way to revert patch?
I've accidentally updated bios with this microcode through lenovo update center.
I doubt this vulnerability will ever affect my work with x230 so do not want to lose in performance.

There is a way to flash older BIOS, but not through Lenovo's official tool. I never tried, but I know some folks here have the know-how.
