I got:

Code: [Select]
C:\Documents and Settings\Owner\Desktop>md5sum Arduino-COMBINED-dfu-usbserial-atmega16u2-Uno-Rev3.hex
374845d004d03c6ca0535bb4b6f19235 *Arduino-COMBINED-dfu-usbserial-atmega16u2-Uno-Rev3.hex

Same as before:

Code: [Select]
MD5 (Arduino-COMBINED-dfu-usbserial-atmega16u2-Uno-Rev3.hex) = 374845d004d03c6ca0535bb4b6f19235
