ZWZ PE

E

Introduction and Purpose

Message: This project's goal is to extend the possibilities of a standard BartPE and to fulfill the dreams of many happy administrators who already got the data back with it.
The purpose is to boot a system from a CD and fix any problems easily without an installation.
Some binaries were developed in order to make this possible - loading the CD into the computer RAM to allow various other software to be installed or burnt while maintaining the compatibility with weaker systems. ZWZ PE will load from the CD on systems with as little RAM as 64 MB. Other binaries from third parties were modified to make them work under PE.

Requirements

Message: Aside of an x86 computer with an optical drive and at least 64 MB RAM, you will have to download some software packages.
  • PE Builder by Bart.
  • Service Pack 1 for Windows 2003, English. This is important.
  • Optionally WinRAR, it will make the required extraction of the SP1 files easier. Also copy RAR.EXE into the FAR directory.
  • FAR. This should become the only file manager in PE, because Explorer doesn't work and A43 is quite cumbersome. There is no serious limitation in the evaluation version and it works really well in PE.
  • Optionally Panel, my own ancient solution for adding icons. It's simpler than NU2MENU (a part of PE Builder) and you'll like it.
  • English Windows XP or any Windows 2003 without a Service Pack. You can fool the SP1 to convert a Windows installation into English by taking [servicepack]\i386\ia\hive*.inf and overwriting them to [windowsinstall]\i386. Use Google to learn how to INTEGRATE a Service Pack.
  • Binaries from here, especially BOOTZWZ and BARTPLDR.
  • Text files created from snippets on this page or downloaded. As the binary downloads may get lost due to bandwidth constraints, I will give you instructions how to make everything yourself whenever possible.

    Message: In this section I will explain the making of the necessary files. You should be able to suffice without downloading anything off this site if you are limited to Google cache, for example.

    As you can see, this file uses two binaries. To obtain bootzwz.dat, run ISOBuster, open the Windows CD (any XP will suffice) and save the BootImage (2 KB) onto disk. The file is also supplied by PE Builder as bootsect.bin. Then use a hex editor (edit /64 is enough) and cut it like this:
    Delete the first 4 bytes. Save and verify that the file is now 2044 bytes long. Then delete from the end and truncate the file to 1182 bytes in length.
    Next is the isol2inc.bin. Download the SYSLINUX package and extract isolinux-debug.bin from it. The non-debug version is unusable in this project! Follow the remarks at the end of the ASM code. I used Sourcer as a disassembler for this purpose. If you have access to Linux with all the includes that ISOLINUX.ASM requires, you can just double the inc eax instruction and compile it and that should be OK.
    Now run nbasm32 bootzwz.asm and it should produce bootzwz.com. When renaming to bootzwz.bin, pay attention to making it lowercase or it won't work right!
    Put bootzwz.bin into the root BartPE CD directory and also into a new Include directory, which has to be configured in PE Builder. This is to assure that the file will be added when you rebuild the CD with PE Builder.

  • BARTPLDR
  • We need two separate LDRs, one that will handle low-memory systems booting from CD and another that will copy the CD into RAM first so that you can use the optical drive for other purposes later. (That requires more RAM, however.)
    Here is how you can prepare BARTPLDR.BIN. The goal is to make this file use a different configuration than SETUPLDR.BIN. We cannot just add [CD_root]\winnt.sif, because SETUPLDR would find it also. So it's necessary to change the WINNT.SIF in the binary file to something else.
    Copy i386\SETUPLDR.BIN to BARTPLDR.BIN (same directory). Load it into a hex editor, edit /64 is almost enough, but be cautious and make sure you know how to handle the old DOS editor.
    Search for WINNT.SIF in bartpldr and after toggling Insert to Overwrite mode, overwrite W to V and T to U, keep the letter case the same, i.e. don't replace t with U and so on. The idea behind this is to keep the CRC the same. If you made up an arbitrary name instead of WINNT.SIF, the file would report NTLDR corrupted (regardless the fact that it's not identical to NTLDR and is originally SETUPLDR...)
    If you used edit, save it and exit and then load the same file again, now with the row width of 65 characters (as opposed to 64). EDIT won't find WINNT occurences that broke on the end of the line, so fix the rest of WINNT's to VINNU. Save and place this file into [include_dir]\i386 to keep it after the builder erases the CD directory during any future rebuild.
  • [cd_root+include]\VINNU.SIF
  • [SetupData] BootDevice = "ramdisk(0)" BootPath = "\I386\SYSTEM32\" OsLoadOptions = "/noguiboot /fastdetect /minint /rdexportascd /rdpath=ramdisk.iso"
    Just copy-paste-save this, there's nothing special on this one except that you may want to customize the ramdisk.iso filename into something else. But I do not recommend changing anything as it's likely that it will break the compatibility with some other file.
  • [cd_root+include]\RAMDISK.000
  • Yes, this file has to be created empty. It has to have the same filename length and sort alphabetically the same as the future RAMDISK.ISO and I only chose to use a different extension to see any build problems easily.

  • Self-reference patch
  • Now this is a tricky goodie! This will patch the file RAMDISK.000 in the finished ISO in a way that it will start at sector 0 and have the same length as the ISO, effectively allowing the Windows loader and the user to directly grab the entire CD without any CD-cloning tool. In a previous incarnation, a separately-built ISO was added to the compilation, but this was very inefficient and the PE could not fit on an 8-cm CD. So this solves the problem. One interesting point is that the self-reference continues infinitely, allowing the user to burn a new ZWZ PE CD from within the running environment using CDRECORD. Just supply X:\RAMDISK.ISO as the source CD image.
    A patcher done in Visual Basic 6 follows. Add it to a blank project and set it as the startup module.

    The code is nothing spiffy, somebody should rewrite it in C or Python or something. Compile it into ISOSELF.EXE or fix the batch file below to reference it correctly.
    I build the ISO using a batch file placed in the pebuilder directory. Feel free to customize the CD directory and/or the output ISO name, but I suggest that you keep the default BartPE as the CD directory to avoid unnecessary typos and so on.
  • [pe_builder]\iso.bat
  • @echo off mkisofs.exe -iso-level 4 -force-uppercase -volid "ZWZPE" -b bootzwz.bin -no-emul-boot -boot-load-size 8 -hide boot.catalog -o .\zwzpe.iso "bartpe" isoself /l=isoself.log /i=zwzpe.iso /f=RAMDISK.000 /n=RAMDISK.ISO type isoself.log echo Finished.
    This batch file contains some very important parameters for MKISOFS (you got this with PE Builder), such as the option to load the first 8 HDD-style sectors of bootzwz.bin. The "bartpe" string is the CD directory, you may want to change this if you decided to use another name. VolID is actually the CD's label visible in My computer, for example.

    Linux

    Message: You may add almost any Linux distribution to this PE, but the problem with Ubuntu and possibly other CD-based distributions is that it won't boot from a DVD. Therefore you must either find a tiny distribution that will fit on one CD with PE or use a DVD distribution burnt on a DVD with PE.
    But since the entire ISO gets loaded into RAM as a self-reference, this practice is unrecommended! Only pick minidistros that won't ruin the 8-cm CD concept.
    I chose to add Acronis PartitionExpert in there. You might be lucky to get a bootable CD of PartitionExpert. To get kernel.dat and ramdisk.dat, which are actually vmlinuz and initrd, do the following:
    Make sure that the image is pure ISO, no CUE+BIN or similar!
    Load it into a hex editor, edit /90 is enough...maybe. Find the string BOOTWIZ. The goal is to strip the ISO and make a FAT16 image.
    ˙x╔BOOTWIZ FAT16 3xß.... The three bytes before BOOTWIZ are a jump instruction to the rest of the bootsector code and I believe that they are never executed anyway. So cut all data prior to the "˙". Save the file and get it to some working Linux distribution. Mount it:
    mount -o loop fatfile.fat workingdir where fatfile.fat is what you created and workingdir is an empty directory in the same directory. Next, copy away the two files, kernel.dat and ramdisk.dat. Do not bother with the rest, ISOLINUX will take care of that.
    Get the files back to your Windows and rename them: kernel.dat to acronis.ker and ramdisk.dat to acronis.gz. The latter is important, the name RAMDISK would collide with RAMDISK.ISO due to getting in front of it in alphabet. Put the files in cd_root.
    Make this:
  • [cd_root+include]\isolinux.cfg
  • default acronis.ker append boot= initrd=acronis.gz ramdisk_size=14000000 root=/dev/ram rw quiet vga=788 --
    If you plan to add support for more (presumably mini) distributions, inspire yourself in other isolinux.cfg files seen in other distributions.

    Downloads

    Message: Get the PE Builder from Bart's site linked above and Windows from Microsoft. My software is in the following archives. After the download, don't forget to put the files in different directories, as required in the article above. Do not just extract everything in the pebuilder directory, this won't work after a rebuild and will clutter everything.
    zwzpe.rar (ZWZ server - often offline)
    zwzpe.rar (SZM - should be OK)
    zwzpe.rar (Cabspace - down)
    pkzipc.rar (often offline) (file belongs in the FAR directory and it's not necessary)
    zwzpe-panel.rar (SZM)
    zwzpe-panel.rar (often offline) (file belongs above the FAR directory and it's not necessary). To make PANEL work, edit panel.ini and write a path to an icon followed by the application's executable. Directory is relative to the directory that was current in the script that launched Panel. This makes it the X:\Programs directory:
  • [cd_root+include]\i386\system32\autorun10panel.cmd
  • @echo off title Panel pushd cd /d %SystemRoot% cd\ cd programs start panel popd exit
    Collect .ico icons used by Panel using any icon extractor, I recommend Resource Hacker. Please copy msvbvm60.dll into i386\system32 and also vssapi.dll, which is necessary for the CHKDSK command. Both files can be found in any System32 of Windows XP.

    If you add a neat new feature into any of my software, do not hesitate to mail me.
