here are a lot of post with ISP burner, i use this one it work perfect but only take errors on verify:

CIRCUIT: **broken link removed**
SOFTWARE: **broken link removed**

i made a simpe adapter to program in circuit, no problem only turn off verify if you can't find hct541 you can use ls244 or hc541. To turn off verifying off flash you must download a ver. 3.7 of software.
