Probably many of AVR software developers that use AVRStudio4 environment would like to program chips directly from AVRStudio4 using AVRISP. Usually we use simplified version of AVRISP that work with PonyProg or AVRDUDE. But here is solution, that can solve this problem.
In sixca.com is populated simplified version of AVR ISP programmer that works with ATMEL original programming software.

The PCB is one layer and simple to build:
Installation of components:
The firmware is written for AT90S2313 as this version of microcontroller is obsolete, then it should be working on Attiny2313 as this microcontroller is compatible with AT90S2313. This device can program most of AVR microcontrollers that support ISP:
The firmware is written to work with crystal of 4MHz. The target device has to use 4MHz of crystal. If it uses internal oscillator, then there is no need to connect any crystal.
If target board runs at 8MHz, then firmware has to be re-compiled to run at 8MHz. Open asm code and change line:
.equ xtal_8mhz=0 ; if 0 then 4MHz Xtal
.equ xtal_8mhz=1 ; if 0 then 4MHz Xtal
compile this firmware by using avrasm (AVRStudio will do the job).
