>How I built an stk200 that operates off an ide channel.

> An electrical design with all the trickeyness to work off an ide cable as an stk200 parallel port programmer (less detection bits)

> The no-way-this-gonna-work rapid development, this is my copout style of point to point wiring stuff on the back of veroboard with the power lines done properly with heavier wire. Last image is with a quick loopback test jumper

> Trick linux into creating a parallel port with the right base address. To do this, unload the parport_pc module
rmmod partport_pc
Then do a force load with the new io address, in my case 0x170
modprobe parport_pc io=0x170 irq=none,none,none
Yes, the kernel should tell you your crazy and this probably wont work.
