Hello, Fernando. Do I understand correctly that this method does not work on Award (legacy bios) (non-UEFI)/(non hybrid EFi)?
I tried to do as described on this site with my GA-890GPA-UD3H motherboard (rev. 2.1) (bios 89GPAD32.FF, I also tried to use 89GPAD32.FgF) and SSD Kingspec NX-128 2280 (vid 1E4B, did 1202). But the SSD is not detected in the bios.
I also tried using the OProm ss950.bin, but when I use it, I can’t log into the bios. After the bios information window, a black screen opens with a flashing white line in the upper right corner of the screen, and it does not work to enter the bios, the same situation was with the second SSD kingchuxing.
When I tried to do the same with the GA-970A-DS3 rev 1.0 motherboard, everything worked out (there is a hybrid EFi on this board).
I added modules using CBROM32_1.99.exe.
