DVMT and 0xE2 fix

English | 中文

Instruction

MX150 Only!

0. SUPER IMPORTANT! Modifications only checked on BIOS 603. Neither @FallenChromium nor Cyb is responsible for any damage, all is working for us, but you're doing all on your risk.

   • After several tests, I found that the script is safe for 0906 BIOS.

1. IMPORTANT - Make a backup file using backup.cmd, save output file mybackup.bin somewhere in the cloud. This is a proof-of-concept and not stable revision.

2. Before any other manipulations, make sure PowerShell scripts execution is allowed on your Windows machine. Further info here. I set all of policies (CurrentUser and etc.) to Unrestricted and only after this executables worked for me.

3. Execute bios_unlock.cmd before making any further changes to BIOS.

4. Execute DVMT_set.cmd to make DVMT=64mb. You need to restart to let it work. You can't apply all the patches and restart aftetward as it would apply only the latest patch.

5. Execute CFG_unlock.cmd, restart again.

6. Execute bios_lock.cmd to lock BIOS settings for security.

7. Delete DVMT patches

• Open /EFI/CLOVER/config.plist, delete the following code:

<key>framebuffer-fbmem</key>
<data>AACQAA==</data>
<key>framebuffer-stolenmem</key>
<data>AAAwAQ==</data>

8. Delete Clover MSR 0xE2 patch

• Open /EFI/CLOVER/config.plist, remove the following code:

<dict>
    <key>Comment</key>
    <string>MSR 0xE2 _xcpm_idle instant reboot(c) Pike R. Alpha</string>
    <key>Find</key>
    <data>ILniAAAADzA=</data>
    <key>Replace</key>
    <data>ILniAAAAkJA=</data>
</dict>
