some prerequisites

• knowledge base: pci, kernel modules, initramfs...
• determine muxless or mused: lspci -nnk
• fake a battery: SSDT1.dat
• seemingly no need to hack vBIOS now
• win11 necessary: tpm and secure-boot

a terrible script but include some useful cmd

• TODO: make it more clear, not now though...
