Lenovo B50-30 80ES WIndows 7 ACPI problem
#1
Hi together!

After obtaining a used B50-30 I tried unsuccessfully to install w7x64pro, it always ran into an ACPI error before installation dialog.
Boot error 0x000000a5 acpi
I can only choose w8 or above for BIOS optimizing.
I also tried disable secure boot and disable UEFI and enable legacy.

My question, is there any hidden ACPI or W7 menu in this actual and original BIOS?

https://download.lenovo.com/pccbbs/mobiles/9ccn35ww.exe

Thanks

kind regards, Thomas

Hello!
This issue is not moddable!Sad
I have some problem with my HP laptop dv6 model, it's not support WinXP.
ACPI tables not supported by XP, it's limitation by vendor.
Your limitation like whitelist is worst in Lenovo policy, many users sold their laptops and bought another without same restrictions.

Please,do not post requests me in PM.Bios modding is very dangerous work.If i provide you confirmed modded bios, please donate for my dangerous work https://goo.gl/98BgtO.Thank you!
