In order to flash the laptop, you will need to have access to two EEPROM chips

After the flasher is ready, connect it to your machine and ensure its ready to use:

After the flasher is ready, plug it into a USB port on your machine (leave the clip

|

/>
|
||||
|
||||
Flashrom should report that programmer initialization was a success.
|
||||
A matching line (e.g. `Bus 001 Device 00X: ID 1a86:5512 QinHeng Electronics`)
|

confirms the programmer is plugged in and the host recognises it.

Next, extract the original rom from both EEPROM chips. This is

done by attaching the programmer to the correct chip and running

the subsequent commands. It may take longer than expected, and

ensuring the bios was properly extracted is important before proceeding

further.

Next, extract the original ROM from both EEPROM chips. Do the **4MB (top)

the clip to the **8MB (bottom) chip**.

Each chip is read twice so the two reads can be diffed to catch flaky
