I honestly do not know. There is little info on the Gimp export bmp format around.
As a guess.
Exporting an image with an alpha channel the both a1 and x1 options are enabled
Exporting an image without an alpha channel, then only the x1 option is enabled.
Best guess, for an image with alpha channel, x1 disables the alpha bit.
As a note:
If you are feeding these into another application check the compatibility option. I use bmp format with a linux command line application Autotrace, which needs that turned off. Weird, but there you are.
