I faced an issue on several laptops that have an American Megatrends EFI firmware. When I connect a K30 smardcard reader or PC Twin reader with a .NET card before to start the laptop, the firmware is frozen. When I remove the K30 USB stick, the boot is OK.
I faced the problem on different devices and the common point ids the EFI :
- Surface Pro 2 with American MegaTrends 2.15.1226
- Surface Pro 3 with American MegaTrends 2.16.1243
- ASUS Pro BU 401 L with American Megatrends 2.15.1236
- Clevo laptop with American Megatrends 2.17.1246
Other test :
K30 reader WITHOUT .Net card : OK, no freeze
PC Twin reader with .Net Card inserted : KO, freeze
---> this is really the combination Reader + .Net card inserted that is KO
I don't know if there is a workaround, but it's blocking at each restart our laptops.
Is anybody facing the same issue ?
