AVR-Chat

I am attempting to program an ATMega16 with a serial booloader using:

1) AVRStudio 4.16(build: 628), connect speed lowered to 9600
2) AVR Ice-Cube JTAG device
3) GCC produced HEX file with SW from
http://www.siwawi.arubi.uni-kl.de/avr_projects/ 

I verified that AVRStudio is connected to the processor (I can read the
signature, lock bits, etc.)

Fuses: Bootsize 512, BOOTRST checked, No lockbits set (yet)

I am not vaery familiar with the encoding of the ".hex" files but "main.hex"
looks like this:

:103C000011241FBECFE5D4E0DEBFCDBF10E0A0E69B
:103C1000B0E0EAE7FFE302C005900D92A036B107DD
:103C2000D9F710E0A0E6B0E001C01D92A03EB107B8
:103C3000E1F70E94201E0C94BC1F0C941F1E0895D7
....
:103F400080E38CB95D9BFECF88E314C0933761F4A6
:103F50005D9BFECF83E08CB95D9BFECF84E98CB97D
:103F60005D9BFECF8EE106C09B3109F485CE5D9B43
:0A3F7000FECF8FE38CB980CEFFCFA7
:0400000300003C00BD
:00000001FF

Researching the Intel HEX format on the internet
(http://en.wikipedia.org/wiki/Intel_HEX) this appears to be loading 0x3C00
through 0x3F7A with 0x3C00 having a value of 0x11.

When I use AVRStudio to program "main.hex" I get:

OK
Reading FLASH input file.. OK
Setting device parameters for jtag programming ..OK
Entering programming mode.. OK
Erasing device.. OK
Programming FLASH ..       OK
Reading FLASH ..       OK
WARNING: FLASH byte address 0x3C00 is 0x11 (should be 0x11).. FAILED!
Leaving programming mode.. OK

So, why am I getting a warning that address 0x3C00 does not match when it is
also reporting on the same line that it does match (0x11 does equal 0x11
does it not?) ????

... and I know I'm going to regret asking this one ... If I have specified a
bootloader size of 512, why is the loader starting at 0x3c00? ... 16kb -
0x3c00 = 1024 bytes ... oops, just figured it out -> bootsize is in WORDS
not bytes ... whew, that was close ... :-)
