<p>Hello everybody,</p>
<p>I bought an Elitebook 8570w few years ago, and ever since I've been trying to set up some features to make it work better. However, the BIOS configuration utility is pretty bald, so after reaching out HP Support with no luck and having googled for years,
I'm still wearing nappies.</p>
<p>The main problems are two: ASPM and Intel HD4000. Even though MS-Windows manages to turn off the discrete NVidia K2000M and start using the Intel card, (although in a subtle way, as it won't provide any information about the device in use), I haven't been
able to make it work in Linux (OpenSuse); moreover, it's not even shown with 'lspci'. This means I'm not able to disable dGPU in order to use Intel one for lower power consumption purposes.</p>
<p>As for ASPM, I couldn't find a way of turning it ON other than overriding FADT from the EFIShell. If I do it this way, and add 'pcie_aspm=force' as boot parameter, I still see 'ASPM: Could not configure common clock', and ASPM appears 'disabled' in most
of the devices listed with 'lspci'. Actually, the few that appear 'enabled' if I override FADT will also show that way if I don't. On the other hand, If I don't override FADT, I get 'ACPI FADT declares the system doesn't support PCIe ASPM, so disable it' and
some others.</p>
<p>Few questions: Assuming it's possible to flash the ROM to use 'coreboot' instead of the firmware provided by HP, would I be able to enable at least this two features? will I need to de-solder the ROM chip to do it?, would I lose other functionalities? I
mean, is it possible to know whether all other devices are also supported?</p>
<p>Following the guide I found in FAQs, I attached bellow what I understand is necessary to answer this questions. Please let me know if it's not complete.<br>
</p>
<p>Thanks in advance!</p>

Writes have been disabled for safety reasons. You can enforce write<br>
support with the ich_spi_force programmer option, but you will most likely<br>
harm your hardware! If you force flashrom you will get no support if<br>
something breaks. On a few mainboards it is possible to enable write<br>
access by setting a jumper (see its documentation or the board itself).<br>
