Dear all,
I want to invoke a control method which exists under EC namespace .
But I find no acpiec.sys in vista.
Therefore, I cant invoke it in vista due to without apciec.sys device
object.
Does anybody knows how to solve it?
Thanks
hanks
================================================================================================================================================================
The device object is still there. It just doesn’t have acpiec.sys loaded on
top of it. The IDs are still the same.

Dear Jake,
What kind of IDs?
Any you mean I can make use of IDs to get device object?
Btw, How to use IOCTL_ACPI_EVAL_METHOD_EX ?
Are there any sample code? I hardly find any relative information.
Thank you
Hanks

Dear Jake,
I still can’t find correct way to get device object of acpiec.sys in
vista.
Could you please give me a hand?
Best regards,

I’ve checked with the people who currently own this code to make sure that
my story is straight. (I no longer work in the group involved.)
From Windows 2000 through Vista, there has been an acpi.sys which would
enumerate lots and lots of nodes, consuming many of them internally. If you
go into Device Manager, choose “show hidden devices” and “show devices by
connection” (we call this one “show as God intended” internally) you will
then see quite a few device nodes which only have acpi.sys loaded on them,
many of which have child nodes. Some of the child nodes have other drivers
loaded on top of them.
In Windows 2000 through Windows 2003 Server, the ACPI EC device was one of
these children that had a separate driver loaded on top of it. This was
problematic because acpiec.sys supplied EC operation region support, which
consequently didn’t work until the acpiec.sys driver was loaded. This
caused lots of BIOS guys lots of heartburn and it also prompted some badly
thought-out additions to ACPI 1.0a and 1.0b, mostly notably _REG objects.
So for Windows Vista, the function of acpiec.sys was brought into acpi.sys.
Nothing else was changed. The device node for the EC still exists. It’s ID
is still EISAID(“PNP0C09”). It just has a different driver loaded on top of
it. All other function is exactly the same (or so they promise me.)
I suspect that if you back up and stop looking for acpiec.sys and start
looking for EISAID(“PNP0C09”) instead, you’ll find a solution that works for
all versions of Windows since Win98.
