I have an acer nitro 5 AN515-52-77S9 laptop. The driver page has listed a new BIOS update which says "1. Add ABST support. 2. Update Microcode to 0x96" Can someone please explain what does ABST mean? I assume microcode is something related to intel drivers. Is that right? Also, in case the new BIOS causes some instability, can i revert it back? Thanks in advance.
