HI guys, suddenly my computer wont detect displayport. Only hdmi, then I messed up with Compatibility Support Module (CSM) from Enabled, and PCIE setting to UEFI instead of legacy. Now I dont have any display, and Motherboard (Asus Deluxe X99 II) shows the q-code A2.

Right now tried remove the CMOS battery for 30 mins, hoping all settings would reset, but no avail.

Now I'm trying USB BIOS Flashback via this website https://www.asus.com/us/support/FAQ/1013998/
https://event.asus.com/2012/mb/usb_bios_flashback_guide/

but it only shows the X99 first generation, I own the second one X99 Deluxe II, and it wont work since it had a file name for the X99, not the X99 II.

Will be looking forward for your reply. Thanks so much!
