Whatever, I can not list here all the models, below is the method to find such filename info:
1. Extract ROM file from EXE: xxxxx.exe -writeromfile;
2. Use a tool decode the xxxxx.rom to xxxxxx.bin;
3. Open xxxxxx.bin by Winhex, Ctrl + F search "hdr", F3 search for the next, it's easy to find the string with ????HDR.?????HDC.?????BIN;
That will be the right filename which can be used for the BIOS recovery.
