Hello to everybody!!!
This is a nettop pc (thin client) from China named Wanlida PC8001H, it has Intel Atom N270, 1Gb of DDR3, integrated intel graphic, wi-fi module etc. Motherboard seems like a laptop system board.
1. BIOS is Inside H2O ver. D0.05T45.35.07 (show on main menu), I backup it by Universal BIOS backup Toolkit 2.0,

2. Now opened 4 menus: Main; Security; Boot; Exit and hide Advanced and Power. photo:

3. I very need to change graphic parameters in advanced menu, but Advanced menu is hide.
I has tested many programs and choose Universal BIOS backup Toolkit 2.0 to backup BIOS, Flashit 2.0b to flash bios, EFI IFR Dumper to find what to change in bios and I used j-bios.py script to replace menu, but it has a error.
BIOS is not UEFI and I cann't use UEFI Shell.
I even try to disassemble my BIOS (thanks to Donovan6000's blog) and find that my skill in disassemling is bad
I'm not founded how to recover bad BIOS (if it will not works), but I can solder it and flash in programmer CH431A.
I ask to help me unhide Advanced menu or replace Security and Advanced menus, or say how I can change some bytes in bios like in UEFI Shell, important for me bytes is 0x57h, 0x59h, 0x5Ah
Thanks a lot!!!
