Default DVI lock? anyone heard of this??

This morning my monitor wouldnt work. I figured no signal since it was just black and the power light was flashing. I assumed it was my mobo bc I have onboard video. I dont have a vga port just a dvi so I swapped mobos and am now using vga on a different monitor.

A buddy of mine says he experiences this from time to time and its the DVI locking up or freezing. He runs a "program" via floppy at start up to unlock the DVI. He claims he inserts the floppy and restarts the computer and then it works.

Anyone heard of this? I cant find anyone who has. He forwarded me the file but I dont even have a floppy drive. I guess I can usb thumb drive it but my screen is black I cant even see if its doing anything.

I havent attempted it yet bc I have to swap mobos again to do it on the DVI mobo. Thought Id ask before going through the trouble of a mobo swap again.

Maybe the term lock isnt correct. That is the term he used with me, but it sounds like its some sort of freeze or disablement in the DVI output.

I just talked to him. He had an issue once and called Dell tech support and they told him it locks up and gave him the file to use to unlock/unfreeze it.

Well whatever it is it appears to have worked.

I had no signal and a black screen, I ran a floppy with the program and now Im back up and running.

I cant be sure it was that because I swapped various things out and went back and forth, and even had to install a floppy drive but in the end im running the original configuration with the original parts. Only difference was that I ran the floppy.

You can zip them, and upload them to my file upload website.. http://xsupload.co.uk/

You could used any other upload website, too. I know I linked to my site... If you have a problem with that, tell me and I will remove the link.

Edit: it would apear that it does somthing to the EDID.. http://en.wikipedia.org/wiki/Extende...ification_data
