you need a old time floppy drive plug into motherboard use a ps2 keyboard not usb press Ctrl + Home floppy will start up and flash with amiboot.rom
Many THX for your help but I just try with old, readable FDD and PS/2 keyboard Ctrl+home with no success. Same above screen. Before, I acidentally flash it with TA790GXE 128MB I found that if there is no AMIBOOT.ROM file in USB Flash/USB FDD/FDD, the system did not start Recovery (black screen only). If AMIBOOT.ROM file exist, it start Flash Recovery but no success.
I had a very similar experience with a gigabyte motherboard sometime ago. The motherboard was manufactured with different version numbers. I was trying to recover the bios using version 1.0 on a version 2.0 motherboard. Once i had realised my mistake and downloaded the corect version 2.0 bios the recovery process worked. Are you sure you are using the correct bios for your motherboard eg TA790GXE 128 version xx
Yeah! Sure that I downloaded correct BIOS version to recover. I only made mistake first time of flashing.
