DVMT and 0xE2 fix

English | 中文

MX150 Only!

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.
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.
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.
Execute bios_unlock.cmd before making any further changes to BIOS.
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.
Execute CFG_unlock.cmd, restart again.
Execute bios_lock.cmd to lock BIOS settings for security.
