戴尔DELL 2021-02-03

OptiPlex – 9020 – Catalina

Tested on:

  • OptiPlex 9020m

You need to run

setup_var 0x263 0x03 and setup_var 0xDA2 0x00

in Grub to update DVMT settings first and after everytime you reset your bios.

请在放置EFI前在Grub中修改DVMT设置。默认8Bit的显存容量不足以引导系统启动。

This command works FOR 9020 ONLY!

此命令仅对9020有效,在其他电脑上运行可能会损坏BIOS。

Use this on other model may damage your computer!

 

FileVault加密不可打开,开启会导致无法启动。

NEVER enable FileVault on a hackintosh.
