Hello,
After performing a BIOS reset and installing a brand-new BIOS downloaded from the HP Software and Driver website (using my PC's serial number and the corresponding .bin file), I installed it via FreeDOS.
After the installation was successful, I checked the system information in the BIOS and noticed that my integrated MAC address is missing. It now shows as FFFFFFFFFFFF, which is the reason my Ethernet adapter is not working.
Can you please assist me in restoring the MAC address or provide a solution to resolve this issue? I am unable to get the Ethernet connection working due to this problem.
