PRESARIO CQ58-100SL: FAULTY BIOS, IS POSSIBLE TO DOWNGRADE IT SAFELY?

Nicely,
I'll report my problem and I performed the steps in debugging.

Intro: Win10 already installed and updated with all devices properly installed and works perfectly, I decided to update the BIOS to the original and very old F.02 to a last F.29 (AMD platform).

Since then, cord realtek nic has disappeared from the windows Device Manager and:

  1. In the BIOS, in the command menu boot device (legacy and uefi), the cable network is the only one marked with an exclamation point (e.g.! network card)
  2. A device for the next conflict appears in Device Manager Windows: pci\ven_1022 & dev_43a1 & subsys_00001022
    The error message is: the specified device generates a resource conflict. (Code 12). To use this device will need to disable one of the other devices in the system.

I tried to:

  1. Reinstall the operating system
  2. uninstall the device in conflict, and then restart the operating system
  3. run windows update check if AMD has seem some drivers updated on its website; the only ones available are those for the chipset: http://support.amd.com/it-it/download/desktop/lega cy? product = legacy4 & os = Windows 2010% 20-% 2064

Consider that:

  1. another user of this forum has the same identical problem with the same bios F.29
  2. previous versions of BIOS fixed lan similar questions about win8 nic so I think that this could be a similar case
  3. Win7 does not suffer from this problem

My questions are:

  1. I can downgrade the BIOS by using a safe procedure or would be risky?
  2. I can draw attention to HP about this problem (and how) or would be useless because the laptop is 4years old?
  3. I try something else to solve the problem without flashing the BIOS again?

Any help would be very much appreciated.

Thank you.

Hi @Mrstenter,

I didn't have the HP_TOOL partition because I just installed a new SSD so the Recovery Manager did not start using the key combination.

In any case, it was enough to download F.27 previous BIOS version and run the HP update from windows and... the network device conflict has been resolved!

While I did not understand the syntax to allow the performer Forum take command of the mention, in any case this isn't a big problem.

Thank you.

Damiano
