Hardware Abstraction layer ?

hi,

1) What Changes Are Done In Vista For Hardware Abstraction Layer(HAL)?

2) Also Do We Need to Do Any Changes in Applications Using HAL?

hi,

Vista will dymanically pick the right HAL during sysprep. With XP, you had
to specify the HAL in sysprep.inf. Vista is more intelligent.

2) Also Do We Need to Do Any Changes in Applications Using HAL?

No.

Thx for the reply...

You mean, that if we change the HAL setting (using HAL slider bar) the
psition value is set in inf file and if we change the same slider bar in
vista it does not get save in inf file.on what basis it picks the right HAL ???

But when an application using DirectX using HAL , In XP, it works
Where as in Vista , no. can u explain me why ???

It's based on the BIOS & Processor that the system is running. If it
running dual-core, it uses a multiprocessor HAL, single core a uniprocessor
HAL, etc.

I have no idea what you are taking about. Changes in the HAL should really
be transparent to the user base. DirectX doesn't have anything to do with
the HAL as far as I know.

OK, but what does it mean "Vista will be HAL independent"

and if XP is HAL dependent ?, then can any application using HAL will work
properly in Vista.

Each XP image is HAL dependent, meaning that you have to have a XP image
for each different HAL that you have. With Vista, you don't need to. It
will pick the HAL based on the hardware you deploy it to now.

Hi,
this for new image deployment. Do you think it will be possible to have a
major hardware change (motherboard, processor...) keeping the disks, and
without reinstalling the OS from scratch? (like in win98)

It will pick the HAL based on the hardware you deploy it to now.
It means that if we are making any application USING HAL for vista, then the
concept is totally wrong, because anyway Vista Pick the HAL on fly.
