Change setting with F8 function~~

[kiros]

Hi all
I have a XPE image. When it boot up, i press F8 key.
And there are some messages were displayed.

Safe Mode,
Safe Mode with Networking,
Safe Mode with Command Prompt,
Enable Boot Logging, Enable VGA Mode, Last Known Good Congiruation...
Debuggin Mode
Start Windows Normally,
Reboot
Return to OS Choices Menu

I know the "Safe mode" is not supported with XPE.
So when i press "Safe Mode with Command Prompt", it show blue screen.

But now i want to do something. I don't know it is possible or not.
For example,when i press "Safe Mode with Command Prompt", i want to
show some screen or run some path file that we want.
Is there any way to change the settings of these options ?
Or is it legal?

Thanks
Kiros

kiros,

I failed to understand why you expected "Safe Mode with Command Prompt" to
be working if Safe Mode is not supported.

If you can't wait until SP2 with this feature coming, you can create your
own "safe mode" image accessible through a boot.ini ntldr menu. For the
"safe mode" image you can create a separate XPe image (even on the same
partition, just use different Windows dir name). With necessary UI provided
(e.g., Command Shell/Minlogon) the image may be small enough and still
provide a good use for recovery or anything relaed you may need.

Hi Konstantin,

I never investigated how safe mode really works, but I always assumed that it uses secondary ControlSet in registry. If this is true
we could make one image that would have two different looks. One for safe mode and one for regular boot. (But this would require
serious registry tweaking after during of after FBA)

Best regards,
Slobodan

Hi Slobodan,

Interesting idea..
Although a few "but"s:
1) The Safe Mode is more complicated (not just secondary ControlSet).
XP uses [HKLM\SYSTEM\CurrentControlSet\Control\SafeBoot\Minimal] for Safe
mode, and [HKLM\SYSTEM\CurrentControlSet\Control\SafeBoot\Network] for Safe
mode with networking.
Basically, in Safe mode XP runs only a subset of the drivers and services.

Read it is high level here:
http://www.microsoft.com/resources/...Windows/XP/all/reskit/en-us/prmc_str_elix.asp

The CurrentSet switching would be useful for LastKnownGood configuration
which does not get updated in Safe mode.

However, I guess it would still be possible to do what you thought. Just
edit/tweak the keys offline.
Don't know, though, if there is anything else used (beside the different
registry entries) in the Safe mode. Most likely, there is (since something
has been fixed in SP2 with regards to the Safe Mode).

2) I believe that having a small *recovery* image on the disk may be
better (more *safe*) option since you easy update anything in the main image
(even replace the entire image). Not to mention (and you know that) that it
is really easy to implement.

3) No reason to mess up with all this, SP2 will have the Safe Mode
supported anyway

Regards,
Konstantin

Hi Konstantin,

1. Interesting info. I just wonder if by filling these lists with valid drivers classes services names we would actually get an
secondary limited boot mode.
SP2 fix could be just presence of valid info in these fields. Binaries are still same and since we have BSOD very early there can be
some other elementary reg field missing (if any).

2. Agree. I do that this way.
3. Special custom kind of safe mode would be nice if possible, but SP2 safe mode will probably do the job ;-)

Best regards,
Slobodan
