Hi!
I have an Asus EeePC 1005PE. If I did it correctly the address would be
84:1. I am attaching the two files so you can check.
Regards,
Henrique.

Sorry I am not using mainline and I can't do such a change right now.

Ok. I added this info to the texinfo manual marking it as "non-confirmed".

That didn't help (and, noticing a typo in your patch, neither did adding
GRUB_BUTTON_CMOS_CLEAN=prettyplease).
I don't know how Windows decides to start up Media Direct, but I think the
best way to solve my problem is to replace the file MDirect.exe with
something innocuous.
Anyway, thanks for trying.

I have a Dell XPS M1330, and GRUB_BUTTON_CMOS_ADDRESS=85:3 works also for me.
However, I do have one question.
I have it set up now to boot directly into Linux when I use the main power-on
button, and I use the auxiliary button to get a boot menu, defaulting
to Windows. But when I boot Windows using that button, it starts up
a MediaDirect setup screen (in addition to regular Windows). Would it be
possible to (optionally) clear the vendor power-on button bit in the
cmos before booting?

[-- Attachment #1: Type: text/plain, Size: 1473 bytes --]
Hello, all. I've just merged vendor power-on button support into
mainline. Here is extract from manual: <<EOF
Some laptop vendors provide an additional power-on button which boots
another OS.
GRUB supports such buttons with GRUB_TIMEOUT_BUTTON, GRUB_DEFAULT_BUTTON,
GRUB_HIDDEN_TIMEOUT_BUTTON and GRUB_BUTTON_CMOS_ADDRESS variables in
default/grub. GRUB_TIMEOUT_BUTTON, GRUB_DEFAULT_BUTTON and
GRUB_HIDDEN_TIMEOUT_BUTTON are used instead of corresponding variables
without
_BUTTON suffix when powered using special button.
GRUB_BUTTON_CMOS_ADDRESS is vendor specific and partially model-specific.
Values known to GRUB team are:
@table @key
@item Dell XPS M1530
85:3
@end table
EOF
If you have a laptop which has a similar feature could you figure your
address and contribute?
To discover the address do the following:
1) boot normally
2) sudo modprobe nvram
sudo cat /dev/nvram | xxd > normal_button.txt
3) boot using vendor button
sudo modprobe nvram
sudo cat /dev/nvram | xxd > normal_vendor.txt
Then compare these text files and find where a bit was toggled. E.g. in
case of Dell XPS it was:
byte 0x47: 20 --> 28
It's a bit number 3 as seen from following table:
0: 01
1: 02
2: 04
3: 08
4: 10
5: 20
6: 40
7: 80
0x47 is decimal 71. Linux nvram implementation cuts first 14 bytes of
CMOS. So the real byte address in CMOS is 71+4=85
So complete address is 85:3
