Check processor and EFI firmware compatibility

I am currently running MX Linux on an HP Chromebook 14. I downloaded and ran the script. It gives the following output:

$ ./ host
Checking if host is capable of running Clear Linux* OS

SUCCESS: 64-bit CPU (lm)
SUCCESS: Supplemental Streaming SIMD Extensions 3 (ssse3)
SUCCESS: Streaming SIMD Extensions v4.1 (sse4_1)
SUCCESS: Streaming SIMD Extensions v4.2 (sse4_2)
FAIL: Advanced Encryption Standard instruction set (aes)

Does this indicate that I will not be able to run Clear Linux* ?

Correct. AES is currently a requirement however there is discussion on loosening the requirement here:

Yep, I found out the old-fashioned way. I created a bootable USB and the boot failed.
