+How to flash:
+ * Download the firmware from:
+ http://support.fujitsu-siemens.de/Download/ShowDescription.asp?SoftwareGUID=6DB401B3-B0BD-43CB-A3AA-6278B23FBCB0
+ * Extract the .exe file with unzip
+ * Place RSB_S2.bin, RSB_S2.001 and RSB_S2_SINGLE.bin in the tftpboot
+ directory. Make sure that all three files are readable!
+ * Initiate the firmware-upgrade from the web interface:
+ - When upgrading from 6.x, flash the RSB_S2.bin file, which
+ will automatically load the RSB_S2.001 file in the process
+ - When upgrading from 7.x, flash the RSB_S2_SINGLE.bin
+ WARNING: NEVER FLASH THE .001 FILES DIRECTLY, THIS WILL BRICK YOUR BOARD!
+ * Modify RSB_S2_SINGLE.bin with 'firmware' and reflash ;-)
+ (Don't try to modify the other files)
