Run the BACKUP_Tools program to obtain a backup of your BIOS (it’ll create results.rar archive on desktop). Also, I need a copy of your BIOS variables (run "GET VARS.bat" from this archive and share with me the output file "vars.txt").
The results archive weights only about 100 kilobytes, so it is almost empty. Something went wrong. Please, backup with this: FPTW 12.0.32.1421.zip.
i dont know how to backup with fptw, only can create biosregionDUMP.bin
but tried to use fisrt backup tool and its file nearly 10mb so hope it will work
thx for answer and help

This is BIOS mod for you: yhaohming.zip. Extract the contents of the archive to a separate folder.
1. Run “SET VARS.bat” and reboot.
2. Run “FLASH.bat”.
After that, please respond whether the process went well or there are some errors interrupting it. I’ll try my best to provide you with proper support.
It takes courage before flashing, it’s work.(yeah)but it doesn’t have ram setting or video config.
THANK FOR TAKING YOUR TIME AND HOPE YOU HAVE A GOOD DAY
you help someone without seeing them, you’re good guy for me
@yhaohming
I’ll fix this promptly…
EDIT: Sometimes still forgetting to save changes. 
While you were managing to generate the second archive, I was making a mod for BIOS version 1.08, but yours turned out to be 1.04. And so it happened.
Re-download.
