sudejau kaip parasyta buvo faile:

# Fuse atmega8 high byte HFUSE:
# 0xc9 = 1 1 0 0   1 0 0 1 <-- BOOTRST (boot reset vector at 0x0000)
#        ^ ^ ^ ^   ^ ^ ^------ BOOTSZ0
#        | | | |   | +-------- BOOTSZ1
#        | | | |   + --------- EESAVE (don't preserve EEPROM over chip 
erase)
#        | | | +-------------- CKOPT (full output swing)
#        | | +---------------- SPIEN (allow serial programming)
#        | +------------------ WDTON (WDT not always on)
#        +-------------------- RSTDISBL (reset pin is enabled)
# Fuse atmega8 low byte LFUSE:

#        ^ ^ \ /   \--+--/
#        | |  |       +------- CKSEL 3..0 (external >8M crystal)

kaip suprantu su ponyprogu tai kur TUSTI langeliai ten = 1
