Title: Everything you wanted to know about WinPE
Post by: scalar on June 20, 2003, 01:12:59 AM

Windows PE is not a standalone CD by itself.

Windows PE is on a special CD called the Windows XP OEM Preinstallation Kit.

It is actually quite tiny, because all that is on the OEM Preinstall CD is a folder with about 1.8 meg of files.

You must have Windows XP Pro in order to get Win PE, because the files on the OEM Preinstall CD are just \"builder files\" pulling bits and pieces from Win XP to built a Win PE CD.

Here is what's in Windows PE:

Code: [Select]

G:\WINPE>dir
 Volume in drive G is XRMOPK_EN
 Volume Serial Number is BA28-A6CE

 Directory of G:\WINPE

               2 Dir(s)               0 bytes free

G:\WINPE>
As you can see, the Win PE builder files are actually ridiculously small. Of the 1.8 megs, 1.4 is used for a silly desktop wallpaer. So the actual size of the WinPE builder files is a mere 478k.

That's really all that stands between Win XP Pro and Windows PE. /smile.gif\' class=\'bbc_emoticon\' alt=\':)\' />

Scalar,

Does that mean that if I put the files listed on to a
bootable cd it should in theory boot into a PE enviroment?

Or does one need the OEM kit to create the installation?

No, it's more than those files. Some of the executables in the \WINPE folder dig through a Win XP Pro CD to make the custom boot image.

Here are what the various WinPE files are for:

• You run MKIMG.CMD to do the actual building process. Put you XP Pro CD in the drive, and tell MKIMG where to put the WinPE build directory and the final ISO image (if desired).
  
• DSKIMG.EXE makes a disk image of a floppy in drive A. What for? On ia64 we need to copy setupldr.efi to floppy and image it and use that as the boot image.
  
• OSCDIMG.EXE takes the build directory on your hard drive and turns it into a bootable CD, with the proper boot sector, boot loader, etc.
  
• ETFSBOOT.COM is really a copy of the CD boot sector. Used by OSCDIMG.EXE to put a bootsector onto the ISO image.
  
• BLDHIVES.EXE creates the custom registry files for WinPE using the registry files on the Win XP CD.
  
• CONFIG.INF used by BLDHIVES.EXE for making the customized WinPE registry.
  

Though FACTORY.EXE and NETCFG.EXE aren't in here, and aren't automatically put onto the ISO by MKIMG. It appears you need to manually install them from the OEM Preinstallation Kit Tools folder. (I need to read the documentation some more.)

So, does anybody know how bldhives.exe is actually working?
I am asking because normal users cannot use it, an admin
can use it only. But I cannot figure out why, and I need it.
