But I can't believe that in case when booting from SD card, that then 
you'll first copy from SD to NAND before copying from NAND to RAM. So I 
still suggest:

a) In case you'll boot from SD card and see that you want to flash the 
bootloader, copy image "splash.rgb16z.flash" instead of "splash.rgb16z" 
from SD to NAND while displaying dark red and empty screen.

b) In case you'll  boot from SD card and see that you will not flash the 
bootloader, copy image "splash.rgb16z" from SD to RAM and display this.

c) In case you'll boot from NAND, you don't have any other chance than 
displaying image "splash.rgb16z.flash" from NAND.

bootloader. Then you will know...

No, in case bootloader version of SD card and NAND are identical, I will 
not know if I did something little wrong with formatting the SD card or 
copying MLO and thus getting booted from NAND instead of SD. But I want to

OK, I'll try what happens.

Best regards
