OS Helpers and Drivers

Provide common interfaces to interact with system drivers/commands

Mostly invoked by HAL modules

Directly invoking helpers from modules should be minimized

Helpers import from BaseHelper

Override applicable functions – default is to generate exception

I/O, PCI, MSR, UEFI Variables, etc.

Create a New Helper

Helper needs to be added into the helper folder with a folder structure like: chipsec/helper/<type>/<type>helper.py


The new helper should be added to chipsec/helper/new/newhelper.py and should import from Helper Base Class

from chipsec.helper.basehelper import Helper
class NewHelper(Helper):

    def __init__(self):
        super(NewHelper, self).__init__()
        self.name = "NewHelper"
