Bios Mods -The Best BIOS Update and Modification Source

I tried to connect, but the usb programmer keeps disconnect when i apply the clip on the chip.

Just to make sure the red pin on the test clip ribbon is the voltage right? The 8th pin on the chip



I use windows 8.1 64bit..Should i run the CH341a programmer in any compatibility mode?

I don't have any idea. I used Windows 7 x64 and USB 2.0 port.

Red pin on the test clip connect to /CS

Hi friend,
can You say which driver You used TTL (used for JTag) or USB (Par2Ser) ?
can You post the link to your version of CH341A Programmer and Clip ?
