Network driver understanding

[mrbacktrac]

Hi guys. I just wana get an understanding on how the drivers in bt work. I have windows 7 with a intel pro N6200 wireless card. In windows i have the drivers 4 the card wich would be installed under my windows system drivers on my hardrive. Ok now when i boot bt4 r2 from usb my card automaticaly works without me installing any linux drivers? How is that posible. Oh and when i run airmon-ng, the card it lists is'nt a intel pro N6200. . .its a intel N4986 or somthing like that? Why is that? Thanx 4 any help.

It all boils down to the software abstraction of the hardware, be it linux or windows driver stacks the hardware remains the same, only the implementation of the software interface" driver"(which controls the hardware) is different between various OS's.
In order to better understand those topics read following books and manuals :Linux device drivers,Prism programmer's manual,Intel Nic 8255x programmer manual.

Thanx for the reply evan though i dont understand a word u said lol. . .can u mayb answer why it works on bt4 r2 when i never installed any drivers? In plain simple english lol! Like does bt4 r2 already have drivers in the iso or what? I think you missed my question

Ok i dnt undestand a word u just said. Why does my card work? I didnt install any drivers? Does bt have drivers already installed or what?

I know they different but could u please answer this. Why does my card work evan though i did not install drivers for it?

Drivers are compiled with linux kernel or drivers are loaded as a modules at runtime/card boot time.
Secondly you asked a very tough question about the inner workings of linux network drivers why do not you try to gain some knowledge only by reading what i mentioned in my post.

[mrbacktrac]

so are you telling me that no one knows if backtrack comes with pre installed drivers for a range of wireless cards?

[iliyapolak]

some drivers are already compiled and present in kernel , other drivers are loaded as a modules at runtime.
Read "linux device drivers"
In windows driver model function drivers (network miniport drivers) are written by the hardware vendor and loaded during hardware installation.

so are you telling me that no one knows if backtrack comes with pre installed drivers for a range of wireless cards?

Backtrack comes with already preinstalled and patched drivers for wireless devices.
Man is it so hard for you to figure this out.?
