Going into device manager, then looking at my graphics card - It has 4 Memory Intervall and 3 I/O intervall and one IRQ.
Shouldn't it only have 1 of each?
I mean, how can it have more than 1 I/O address?
Looking at other devices in the Device manager, I find some that only has "Memory intervall" and "IRQ" at if you click on it -> propterties -> resources.
One example is the "WiFi Adapter". Doesn't it EVERYTHING need an I/O address?
Also, if you could answer this one too:
Question from a book:
"You have bought a new graphics card which you installed according to instructions from a manual. When you boot up the computer, the screen doesn't show anything. What do you do?"
"Test the graphics card in a computer with standard VGA-drivers.
Reset the computer with the old graphics card.
If the card works with the VGA driver, it's probably something wrong with its drivers.
Try lower resolution and a smaller ammount of colors"
So my question:
Doesn't every computer have a VGA-drivers?
I thought that every computer did, and it's those drivers it uses if it can't find any graphics card?
Also, why "Reset the computer with the old graphics card"?
Just one more thing;
a page said
"Each I/O device connected to your computer is mapped to a unique I/O (Input/Output) address. These addresses are assigned to every I/O port on your computer, including USB, Firewire, Ethernet, VGA, and DVI ports, as well as any other ports your computer might have."
But a book has a few questions, the answer to some of them is "Check that there is no IRQ address conflict or I/O address conflict or DMA address conflict"
But if the I/O address is assigned to like USB ports and stuff, then how can there be a conflict?
