UBC is an UEFI BIOS Configurator based on GRUB2 with setup_var
Most laptop manufactures lock down their BIOSes very securely with RSA signing nowadays. This bypasses the dillema of finding a bypass to flash a modified BIOS and instead modifies the NVRAM registers instead.
USE WITH CAUTION AND ENSURE YOU HAVE EXAMINED YOU ARE ACCESSING RIGHT SETUP VARIABLE OR YOU WILL RISK BRICKING YOUR COMPUTER!!! I AM NOT RESPONSIBLE IF ANYTHING HAPPENS TO YOUR COMPUTER, INCLUDING BUT NOT LIMITED TO: SPONTANEOUS COMBUSTION, IMPLOSION, THERMONUCLEAR MELTDOWN. YOU HAVE BEEN FOREWARNED!
Okay in most cases you can recover by removing the CMOS battery or reflashing the eeprom with a programmer no matter how messed up your nvram is. BUT NO PROMISES.
I am not responsible for any losses or damages caused by the use of this program. USE AT YOUR OWN RISK.
