I'm looking to reflash the BIOS software on the motherboard for a Pavilion Desktop - 550-153na.

 

It is not detecting boot devices (SATA SSD or USB).  The BIOS detects the SSD in the storage menu, and will carry out the hardware checks with no problem.

 

The UEFI diagnostics (booted from USB) did not identify any hardware faults.

 

Attempting to run the BIOS recovery goes through a process of various beeps, but fails to complete, with a blinking LED of 2 long and 2 short beeps, which I understand means that the recovery has failed due to the BIOS being corrupt.

 

There are no drivers or BIOS firmware listed on the HP support page any more.

 

The motherboard is ipm17-dd rev 1.04

 

thanks in advance

Below is the link to the parts list for your PC.

 

It has the HP 'Odense' motherboard which has a SSID of 2B47.

 

Below are the info and exe file links to the latest BIOS update HP has for your PC (A0.20):

The problem is I don't believe that there is any way you can run the update without being in Windows.
