I need your help, if you please. In order for this program to work with a variety of NTLdrs, it'd be great to continue to expand the list of supported NTLdrs, below. If you are interested in using this WvBootDD.Sys as an NTBootDD.Sys with your version of NTLdr, you can:
- Download the WvBootDD.zip package: WVBootDD.zip 22KB 17 downloads (version 0.0.1.9)
- Use the contained WNTLdr.exe tool on your NTLdr
- If WNTLdr.exe says "Nothing found," then thanks for trying
- Otherwise, take a look at the list below. If your results are not already in the list, then please post your results!

This experimental NTBootDD.SYS is hard-coded to use a flat hard disk drive image called WIN.HDD in the same filesystem as NTLdr. The file does not need to be contiguous. The "hosting" filesystem can be FATXX, NTFS, ISO9660, or TFTP. A minimal hosting filesystem might contain:
NTLDR BOOT.INI NTDETECT.COM WIN.HDD
This "driver" will [attempt to] present a virtual SCSI disk for booting from. Your BOOT.INI might look something like this:
[boot loader] timeout=30 default=scsi(0)disk(0)rdisk(0)partition(1)WINDOWS [operating systems] scsi(0)disk(0)rdisk(0)partition(1)WINDOWS="Microsoft Windows XP Professional SCSI" /noexecute=optin /fastdetect /sos
This is just for the curious and doesn't have too much practical use just yet.
--- EDIT: November 16th, 2012 ----
Version 0.0.1.9 includes an initial cat command for displaying files on the system volume. Previous version downloaded 7 times. Thanks to Icecube for automating NTLdr discovery! And to Wonko the Sane for reporting an NTLdr version!
--- EDIT: November 11th, 2012 ----
Second version downloaded 57 times. The new version still doesn't do too much. This version includes an .AVI video sample, a sample BOOT.INI, as well as the WNTLdr.exe tool for reporting NTLdr versions.
--- EDIT: 2011 ---
First version downloaded 95 times. Newer version addresses performance but doesn't pass any information to WinVBlock, so use is still limited. This version must be used with the NTLDR from an English Windows XP SP2 with MD5 hash: 9EC920F4179D45AF3A6638A083D39C85.
--- Outdated Notes ---
The NTBOOTDD.SYS file must be patched for every different version of NTLDR. The patch area for this version ranges from 0x12AC through 0x12CC. That is 8 x 4-byte addresses. You must patch the patch area with the following NTLDR functions' and objects' addresses, in this order:
BlPrint() BlOpen() BlRead() AEOpen() BlClose() BlSeek() AEBiosDisabled BlFileTableYou can find these addresses for your version of NTLDR by using this procedure, or we can work together towards figuring out the details of your NTLDR. Otherwise, the attachment here is patched for a Windows XP Professional with Service Pack 2, English edition.
