I desolder it, but now I'm not sure, which way I should solder it back? Does it matter? If I solder it the way it is on the picture, will that be ok? (the yellow one …

Hi. I have multiple laptops, but that Libretto 100CT is driving me crazy. Whenever I use it in dos, it has that strange resolution, that no matter if you put in Bios stretch on or off, leaves black space on the screen. I know that in my 430CDT I used a program like vexp, but it does not work on …

I noticed that some soundboards (awe64g) have speaker connector. What is its purpose? You connect PC speaker device to it, and sound of card comes out on the tiny speaker? Or you connect board output for speaker, so you can hear beep sounds in speakers? Don't know 🙁

Or maybe it is separate computer on card, but will it use rest of computer equipment, like keyboard, gfx card? I don't understand, what is the …
