DSDT from within windows?

DSDT from within windows?

[Jing Su]

Hello All,

After taking a look at (and trying to fix) the broken DSDT for my Acer
TravelMate 382 laptop, I wondered if maybe Windows also allows OEMs to
over-ride the DSDT.  Maybe the hardware guys only had limited time to
provide a hacked up version, and their driver writers  provide a
patched one later.

I've tried some googling, but found no hits thus far.  Anyone know if
it's possible to pull the active DSDT from a running Windows XP
session?  If it's possible, I might be willing to put Windows back on
my laptop (which I'm proud to say is single-boot Linux) just to grab
it and see.

I doubt I'm the first one to think of this, so if there's info about
this being attempted before, let me know.

Thanks,
-Jing

I've no idea how to get it from a live session, but perhaps you
could grep the windows folder for the string "DSDT" to see what
turns up?

It's in registry, with all other ACPI tables:

HKEY_LOCAL_MACHINE\HARDWARE\ACPI\DSDT

Yes, it's possible, see HKEY_LOCAL_MACHINE\HARDWARE\ACPI\DSDT in your 
registry.

RE: DSDT from within windows?

[Moore, Robert]

Seems like the SSDT(s) are not present in the registry, at least with
XP.

iASL -g will grab these tables out of the registry;  I have not seen an
SSDT under HKEY_LOCAL_MACHINE\HARDWARE\ACPI, however.

RE: DSDT from within windows?

[dev_zero]

I have tried overwriting the DSDT in the registry, but
Windows updates the registry everytime windows boots,
so my fixed DSDT gets overwritten. This was just a
project  thought I should try out, and just as  I
suspected, it didn't work.
Do any of you guys know if it's possible to overwrite
the DSDT in windows?

Re: DSDT from within windows?

[dev_zero]

Is it possible to overwrite the DSDT table from windows? I have tried 
overwriting the dsdt table in the registry, but the registry loads the 
DSDT and overwrites mine when Windows starts. Does anyone have any ideas 
about how I can overwrite the DSDT from Windows?
