2.3 BFLASH (Kontron)
In this manual the abbreviation BF is used for BFlash. This also matches with the actual name of the tool
(BF.EXE). BF can be used to read and write data to and from BIOS flash. With this tool it is possible to up-
date the BIOS, change DMI codes, setup vendor codes and save copies of all data. The copies can be used as
master data for mass production.
Type
BF <ret> from DOS prompt to see the BFlash version number and the board version. Only the following
combination of command line arguments has been tested and should be used for the update process.
BF read <BIOS filename> 0 400000
BF write <BIOS filename> 0
3 Custom Logo
With a EFI tool you can create your own custom logo. Use a FAT16/FAT32 formatted device (e.g. a USB key)
and copy the logo tool and the image to the root directory. Then boot the KTA55 board and press the
F7 key
during the boot process (calls the boot menu). Choose the entry ' UEFI: Built-in EFI Shell ' and press Enter.
After the Shell is active type ' fs0: ' and press Enter if you use a USB key - for other boot devices this identi-
fier can be different. You have two options:
change the logo in the ROM-file and update after that the Bios or
change the logo in the flash device.
First option:
KTA55LOGO -i <Bios filename> <Image filename>
-i = input. Change the logo in the ROM-file (input identical with output file)
Note: do not leave any space between '-i' and the Bios filename
Second option:
KTA55LOGO <Image filename>
3.1 Image Format
The following color depths are tested: 4 bit, 8 bit, 8 bit gray scale and 24 bit. As file format you can use the
JPEG (file extension: JPG) or the Windows
® Bitmap (file extension: BMP) format. The JPEG format does not
support gray scale images. Only two resolutions are possible: VGA (640 x 480 pixel) and SVGA (800 x 600
pixel). For higher resolutions the image will be stretched to the display size. Summary:
❐

To activate the logo function in the Bios Setup the entry ' Boot Menu/Enhanced Boot Settings/Dark Boot '
must be ' Enabled '.
