This package contains 2 BIOS modifications for Lenovo ThinkPad X220 laptop.

** Lenovo X220 v1.46 Modified Bios (no whitelist only) **

- Whitelist removal only
- Re-signed with custom key to get rid of 5 beeps on boot

** Lenovo X220 v1.46 Modified Bios (full-blown) **

- Whitelist removal
- Unlocked AES-NI on "no-encryption" machines
- Unlocked hidden advanced menu
- Unlocked memory speed (supports DDR3 1600 and 1866)
- Disabled package c-state lock at MSR 0xE2 (for Hackintosh)
- Re-signed with custom key to get rid of 5 beeps on boot

this is my first time updating and flashing my bios and I know it can brick my machine so I want to make sure I'm doing this right.

my x220 is currently at 1.42.  Do I have to update to 1.43 > 1.44 > 1.45 > 1.46 in that order then update to 1.46 custom bios?
