splash.bmx – what’s a bmx file ?

Take a look at the CEPC bootloader disk images for CE 6.0 (C:\WINCE600\PLATFORM\CEPC\SRC\BOOTLOADER\BIOSLOADER\DISKIMAGES\BOOTDISK) – you will notice a file called splash.bmx which would appear to be some form of bitmap file but can’t be viewed in the Windows Explorer – so how do you view the bmx file, or a better question would be how to replace the existing .bmx file with your own bitmap.

Windows CE 6.0 Platform Builder tool ships with a command line tool called bincompress that gives you the ability to compress/decompress bitmap files to/from the bmx format.

Here’s how the command line looks…

Compresses/Decompresses BIN images to be used with BIOS loader

Usage: bincompress /C|/D infile outfile

/C     compresses <infile> and writes the results to <outfile>
/D     decompressed <infile> and writes the results to <outfile>

So, you could use bincompress to decompress the existing splash.bmx file like so…

Decompressing   : 100%
Input file size : 4582 bytes
Output file size: 10678 bytes

and here’s the output file “foo.bmp”


Of course you can also use bincompress to swap out the Windows CE logo with your own custom logo…

    Hey Mike… Is this a feature of the ce 6 cepc bootloader? I was wondering if I can do this in e-box 2300 bootloader as well.

  2. Mike says:

    there are two eBox bootloaders (actually these are the same as the CEPC bootloaders), the bootloaders are LoadCEPC (which uses MS-DOS to give a menu of boot options), and BIOSLoader.

    So, yes, you can do this on the eBox.
