Guys,
Is it possible to upload arduino bootloader to atmega128?
Which version of arduino should I use ?
I have UsbAsp, can I use it ? How ? I can only upload *.hex file directly from USBasp uploader, but not yet successful on uploading via arduino 1.5 IDE
how can I customize the pin out, as I like ?
which file should I ponder ?
I saw pin_arduino.h but I 'm not sure on how to configure it ??
Any references ?
thanks

Not unchanged but with some adaption this should be no problem.
Which version of arduino should I use ?
The latest stable, which is 1.0.5

You have to modify boards.txt and add an entry for your ATmega128 board there.
how can I customize the pin out, as I like ?
What do you mean by that? Changing the translation from the Arduino pin numbering to the actual ports?
I saw pin_arduino.h but I 'm not sure on how to configure it ??
You don't have to change it but to make a new variant, so create a new directory for your variant and copy pin_arduino.h there and modify that copy. You have to modify it according to the pinout you've chosen.

In the variants directory there are many examples for the existing Arduino models, the reference for it is in the datasheet of the processor. If you mean that you're looking for a step-by-step guide, no, this doesn't exist, because such a task is nothing for a beginner and an experienced Arduino user doesn't need one.
