Hi everyone,

I have just equipped my Aspire A515-43 with a Samsung 980 SSD PCIe Gen 3 x4. But it delivers only 1800 Mb/s instead of the nominal 3500. I guess it's because the Bios is set to x2.
Too bad ! But it's impossible to change it in the normal Bios.
How can I access to the hidden Bios ?
Thanks in advance for your help
