If you want to get your BIOS recovered, then you will need to download version 2.0 of the BIOS package found on the support page. Extract the AWD.rar archive twice and then extract again the archive you found (5008-141.003). You will have a BIN file which you will need to copy to a CD or USB stick and then start the computer. Enter BIOS setup and choose Flash or Recovery from advanced menu. Insert the CD or USB stick and start the procedure by choosing the file from these storage devices and wait for BIOS to flash. The computer will restart eventually and you will be able to boot again. At first, booting will take place, you will enter BIOS again to perform configuration and then you can start it normally.
