The BIOS was dumped using Universal BIOS Backup ToolKit 2.0, the manufacturer doesn't have any BIOS available on the Internet.
That file is the BIOS.BAK made by SWinFlash. The program don't let me flash it, it says that the BIOS present in the computer and the dump checksums match.
@Serg008 thanks for the quick reply. I tested the version you posted and I have some problems with it. 1.) When the computer boots up ( with the new card in ) it halts and returns lots of conflicts ( see image 1 ) View attachment 18577 2.) When windows boots up it lists a lot of unknown devices but the atheros card is nowhere to be found and all of them have hardware id 0001 and device id 0023 ( as seen in this image ) View attachment 18576 PS: it works with the old card without an glitch and in windows it does not show up lots of unknown device. Thank again
