EX485 Can't access BIOS with home made VGA Cable

I had posted an earlier thread EX485 Can't access BIOS with USB keyboard J2 closed" never saw it approved for the masses....

Tonight I wanted to posted a different thread.

I have been trying in vain to access the BIOS on an EX485 which I had just installed 4 gig of memory and a new 750G HD. Completed a fresh install. I wanted change the BOIS PECI=1 to get ready to install a Q8200s. but no matter what I did i couldn't gain access with a USB keyboard to the BOIS and yes J2 is closed with Keyboard in lower USB slot in rear.

Now here's the not so fun part.................

I spent many hours thru this endeavor. Following the forum I made a VGA adapter only for the header on the EX485 because I got tired of moving the VOV cable from my EX470. The VGA cable worked flawlessly, I didn't have any trouble with the video to the monitor attached to the EX485. Because I had seen so many folks talk about the VOV, I was lucky enough to snag a VOV on ebay a while back I had it in another MSS

With the home-made VGA cable in the EX485 I couldn't access BIOS with USB keyboard. Just on a hunch I decided to pull the VOV made cable which has PS2 keyboard and mouse connections from my EX470 and move it to the EX485.

Much to my surprise the upon booting I press the delete key and Entered the BIOS on the EX485......


Okay big brains can someone tell me what this is about I have never read on the forums an issue like this..... I'm very curious to know this one.

Thanks in advance
