After upgrading the BIOS to the version 2.32, I have the following problem: First, the network card Intel 82579LM didn't work and only got into the network after disabling and reenabling it, similar to this issue report.
- Since downgrading the BIOS is not allowed and made impossible by HP, I tried reflashing the newest BIOS v2.32 first, didn't help.
- Then I tried reinstalling Windows 7 x64 and the necessary drivers. After that, the network card didn't start at all (Code 10), even after disabling and reenabling it in the device manager.
- I reset the BIOS using the CMOS clear button. It did reset all settings, but the network still doesn't work.
- I noticed the Management Engine Firmware Version in the BIOS was not shown, so I tried updating the Firmware. Both the Windows 7 firmware update tool and the DOS update Tool do not work and abort with the error "Error 8193: Intel (R) ME Interface : Cannot locate ME device driver"
I assume that the ME firmware is necessary for the network card to correctly initialize, and the newest BIOS doesn't work correctly with whatever old ME firmware is currently in the flash. How can I downgrade the BIOS back to an old Version to try to get the ME Firmware updated and the network card back running?
