Hi Ivan.
Thank you for your response.
The way to retrieve the ROM file is very simple.
Please run Vx20-120.EXE and see "C:/Users/xxxxx/AppData/Local/Temp/_xxx.tmp"(It is possible on any PC)
There should be 4 files there.
7C4D1P39.ROM
FoxAwdWINFLASH.sys
FoxAwdWINFLASH64.sys
WinFlash.exe
1.2.0 7C4D1P39.ROM
1.2.4 7C4D1P43.ROM
1.3.0 7C4D1P45.ROM
Oh, I gave it a wrong file name.
The file name is incorrect, but 7C4D1P43withXeon.rom is based on 1.2.0.
When looking at 7C4D1P43withXeon.rom in binary, you can check 7C4D1P39 at the file end.
