to set this size in the fuse bits… You can also redirect the reset vector
to point to your bootloader instead of address 0x0000 in Flash so that the

<p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size:
12.0pt'>Regarding the bootloader ; I know if I can select its size in the
fuses and this much then take up x amount of EPROM ( I am guessing, I am have
not had chance to read any of the app notes yet). SO my question is that when I
address the EPROM i.e to save variables can I still go from address 0 to the
end? Or does the complier not adjust for this, thus starting at address 0 would
write over the bootloader.<o:p></o:p></span></font></p>
