And finally, I added an oscilloscope to the voltage shunt and a logic analyzer to serial lines, for good measure.Īfter checking connectivity to the bootrom and that I was getting power traces, it was time to dive in.

I also attached a ChipWhisperer with a shunt sensor board to the EC's power line. I've then attached an STM32F303RE on a Nucleo board as a general interface board to the EC's serial and reset. Let's break this thing! I've etched a new board that lets me access important pins (serial TX, RX, CLK, BUSY RST and power lines) without having to fiddle with the previous hacky breakout board. After another long hiatus, I've come back to this project. After procrastinating for a couple of years we now have the flash dump of the EC, which we are now reverse-engineering. We have so far dumped the BIOS from the FWH memory on board, reverse engineered it enough to find out it uses the EC (a Renesas M306K9FCLRP 16-bit micro) in order to check the password and password reset response. As a long-term goal we're thinking of porting Coreboot to them. The aim is to uderstand the laptop boot process better, with an immediate goal of writing a keygen for its' challenge/response mechanism, allowing us to actually boot them and use them as a lightweight Internet access platform. Since they are enterprisey laptops, we cannot just reset their password by unplugging the CMOS battery. We have acquired a bunch of BIOS locked Toshiba Portege R100 laptops. What you need to do, is remove the jumper and. When you find the jumper, look carefully. Most of the manufacturer label the jumper as CLR, CLEAR, CLEAR CMOS, etc.
