what about drivers??

sorry for not writting in arabic

I noticed that some drivers ((specially modems )) works under one destrubution but not the other

and I wonder about the reason ??
Is there a special driver for each hardwa
or is it because of the kernel??


another thing
if I configured my kernel vergion or had apre-configured the way i like
but I have to configure for a newer vergion bwcause of new feather
do I have to go over that compiling thing??
can't I save the feathers that I compiled my existing vergion and just add them to the new kernel??

about the drivers
modes in linux is a tricky story
do you know that the new pci internal modems are NOT modems !! wow
that the reson it may not work in certain OS
since they are not medems they have drivers that emulate the modems
but if there is no driver
it won't act like modems so the OS won't know it
-------
linux do not need drivers for card that follows some standerds
ie most cards are known by the kernel
but if the card emulate standers the kernel won't know it
-------------
SUMMARY: real modems are defined by kernel
soft modems(fake modems) are defined by drivers
if a driver work for some kernel and distro it will work for other distro if they have the same kernel version
