When I try to create the UPD File, I get a error: C:\Kontron\tools\$$_BootLogo_4_UEFI_V1.05\V1.05>UefiModL.exe /MC /S D3633-S1.UPD /T LOGO.UPD /LOGO_SRC FJ-Logo_new.bmp UefiModL Version 6.75 Copyright (c) 2017 Fujitsu Technology Solutions Target file write error I run the cmd elevated (as Admin). Write rights are checked. Any Idea, whats wrong? I tested on two win10 and on one w8.1 installations - always the same problem. EDIT: I installed now a 32bit Windows 10, because all other machines where 64bit - but I get the same error. Can somebody remember the Windows version used before? I also checked with Process Monitor if that tool trys to create the LOGO.UPD file - but no, there is no note about that. I see, that the tool reads the source and logo file, thats is.... Also checked with a older source upd file from an older bios version - again the same.
Windows-version doesn't matter. Perhaps your image-file is too big for the .upd-file or has not the right resolution. Please attach your image-file and upd.-file, i will try to generate an update-file. It is also possible to change the bootlogo permanent without the tool, manual editing in hex-editor and UEFITool will do the same, but bios has to be flashed with Intel Flash Programming Tool.
I have absolutely no idea, why the tool is useless for now: I tried several different machines with Windows XP, 7 and 10 and got always the same error as you "Target file write error". I'm very sure it worked in the past. Perhaps an update made it useless. For luck, you should be able to flash the bootlogo directly without modding the .upd-file with the crappy UefimodL-tool: (partly copied from MANUFACTURING TOOLS-How-To) Hope it will work. Attached is the actual default bootlogo-file, after download change the extension from .txt to .bmp! I extracted it from the bios-file with uefitool.
Thanks, that is working Code: C:\Users\User\Downloads\Kontron\D3633-S1x.R1.12.0\Windows\DeskFlash64Bit>DskFlash.exe /UPDATELOGO /ARB /O=FJ-Logo_new.bmp Configuring environment ..
