Is this SP1 32/64?

Hmm we already have concluded that there doesn't exist any pxe version. Just one 1 compressed and 1 uncompressed, essensially the same. It is win7 sp0 version. I will not bother with any bootmgr before win7, as any bootmgr can boot any winload.exe (except longhorn bootmgr and x64 win7 winload.exe). Btw, vista's bootmgr was not compressed I think, at least not sp0. For me it is faster to just recompile uncompressed bootmgr.exe with modified stub so you don't have to compress again before testing (saves you 1 step).

@marcusj, okay so I have some reports that it is definitely working, and other reports that it isn't (with the old version), must be some minute setup difference...

@Benjamin awesome idea, you should start working on a bootskin using the GUI application

@joakim:
I dunno, whatever marcusj gave me for 32-bit files, which I think is SP1.
Right, no pxe version. The alternate stub thing works. The bootmgr.exe in my Vista 32-bit SP2 is compressed which is how I found this bug.

I would like to update everyone on my progress.

I have successfully made a program that can do all the previously mentioned updates in winload.exe et al. It still requires testsigning to be on for bootmgr and winload.exe to be signed. I have tried my original bootmgr.exe hack and it failed. I will try the new hack later.

@joakim: you posted a new bootmgr hack to allow bootmgr.exe to be unsigned that I didn't understand. Also, I would like it to be for the original Windows 7 bootmgr (not the special one you have).

Also, I have increased the accuracy of the preview (the preview is still has slightly shifted text and the background color may not be quite perfect compared to the real boot up).

Hopefully I will find this bootmgr / bootmgr.exe fix soon... then I will upload a real new version.

The offsets (VA) are still the same so it should work. Which hack by the way? (I used original win7 rtm).

I had a look at the 004439A5 issue late last night, but could could not come up with anything. I just realized that since with don't have enough space for the required code at 004439A5, we must write the code somewhere else where space exist. I did not have time to test this, but I found an empty chunck of space (00's) at 00467200. We could try to write the code there (and close it with a ret instruction), and make a call to that location at around 004439A5.

Realistically I will not have time to test it for a few days, but maybe you will..

Thaimin,

the files i uploaded for you were NOT SP1

they were SP0 the only difference is that one file had been updated through Windows update from RTM to after RTM BEFORE SP1

basically it was an update but defitanitally not SP1

@joakim, so I am currently using your 'original' bootmgr hack:
74 16 57 68 F8 96 46 00 > 75 16 57 68 F8 96 46 00
but you recently stated that when debugging that causes problem and gave some other fix which I didn't understand.
Also, the text color is not all that important at the moment. I plan to go through 'additional' modification testing after I get a completely working version. I plan to look at text justification, making copyright text longer, and startup text color.

@marcusj0015
Sorry for misunderstanding. Truth is now I have tested with a pure un-updated winload.exe 32-bit and it works great, and also for the Windows-Updated one you gave me. Have not tested SP1 versions...

@all
It was brought to my attention that resuming from hibernation uses a similar animation except that the text is "Resuming Windows" instead of "Starting Windows". Additionally, my program does not seem to change the animation at all, it uses the original Windows Logo! So apparently the animation is stored in multiple places... Maybe WinRE or the hidden partition is used for resuming?

Thaimin,

are you sure that resuming windows dosent call teh same bootres.dll? ''becaue the string Resuming Windows IS held in resume.exe

so it could require just the string being patched

I got a clarification. If using the current program resuming reverts to a lame white progress bar on black background (like when WinRE is booting up). Thus, resume.exe needs some hacks to get it to continue using the modified bootres.dll, but it does use the same bootres.dll. I will work on that after I get it working with winload.exe.
