HORM hibernate.sys file size

My XPe system has a 1.0G CF Drive and 1.0G system RAM.
A good portion of the system RAM is used for an EWF overlay.

However, I have not yet seen "c:\hiberfil.sys".
The hibernate file must be the same size as system RAM. It looks like
(Ha,Ha!) there is not room for it on the CF Drive. My compact flash drive
has 711MB used for XPe and Applications and 269MB free space.

Is there a way to use this 269MB for "c:\hiberfil.sys", and still leave the
remaining system RAM for the EWF overlay?

I know that the EWF overlay and XPe RAM are allocated from the same 'pool'.
It does not seem necessary for the hibernate file to contain the EWF overlay.

thanks

Hi Jim,

Someone from MS may chime in here, but I don't think the hibernation
plumbing in XP is EWF "aware" so the hiberfile is still just the complete
contents of RAM.

HTH,

Nothing was changed with regards to hibernation, it just takes all of RAM
(including RAM overlay) and puts it into a hiberfil.sys. You don't see the
hiberfil.sys because there is not enough room on the drive for the file.

Thanks Sean,

It seems that only a limited number embedded systems will be able to take
advantage of HORM, because of the CF/RAM memory structure. Also, the HORM
saving in restart time must be minimized because of the large hibernate file.

I am now pushing to use Minlogon and a Command shell. If Explorer.exe can
be convinced to show a taskbar, desktop, etc, this will be a nice setup. It
looks like registry settings may provide this.

thanks for all of this good help,
