Hello! I have the above programmer. I work in IT and we wanted to work on some machines we are receiving back with BIOS admin passwords. Usually from takeovers that had IT departments that left.
I got the programmer today and have tried it on three different winbond chips. (an HP 840 G5 32MB and 16 MB chip and a Lenovo A485 16MB chip) All 8 pin BIOS ROM chips. One 32mb and Two 16mb.
Anyway, I am using the plier/probe connection that the kit came with to the only adapter it fits on with the programmer. The names on the adapter are similar, but not identical to what the software calls for you to use adapter-wise. For example, it says to use SOIC-8>DIP8, but the actual adapter says SOP8>DIP8. There was several adapters included, all saying SOP instead of SOIC so I figured maybe it was a translation error or something.
I will include the pictures below in the comments, but I have been doing the following:
Pin 1 on the chip is usually the dot in the corner, so I line up the red wire of the cable of the probe with that side of the chip. It goes back to the programmer and pin 1 of the adapter is in pin 1 of the ZIF slot as called for.
Every time I try to read from the pins I get "pins detected but overcurrent (VCC), maybe IC flipped?" error. So I try flipping the cable. I try flipping the adapter. I flip the probe. I desoldered one of the chips and tried it standalone. I tried using different packages of the same name. (i.e. the WBON8 instead of SOIC8 version of W25Q128FW chip.) Nothing. Same error every time.
As I said above I will include photos in the comments. I would appreciate if anyone here is familiar could maybe tell me what I'm doing wrong. I consulted the instructions, but no photos and no references to the adapter or probe. The correct software is installed (came with an install CD) and I can only verify this because it does actually detect the pins and know when it's connected to SOMETHING.
Thanks in advance!
