Swapping BOOTVID.DLL - 2000, XP, ReactOS

[Dz3n]

BOOTVID.DLL is responsible for kernel graphics! Kernel asks it to draw boot screen and blue screen of death. I will show only visible changes.

Windows 2000 with XP bootvid:

We can see only different font here.

We need to hack newer executable so Windows 2000 can use it

Windows 2000 with ReactOS bootvid:

Boot hangs, but animation is still working. Also some graphical glitches.

Windows XP with 2000 bootvid:

Different font

Windows XP with ReactOS bootvid:

Graphical glitch. Similar font.

ReactOS with 2000 bootvid:

Different font

Crazy graphical glitch in SCREEN mode.

Different font in BSOD.

ReactOS with XP bootvid:
No screenshots, there's the same glitch in SCREEN mode.

XP x64 failed to boot with Vista x64 bootvid.
Vista x64 boots with XP x64 bootvid and Windows 10 1809 bootvid but without visible changes.
Somebody may try swapping with beta versions of Windows 2000 or Whistler.

What about NT4's BOOTVID.DLL? Is it the same as 2000/Whistler?

There's no such thing in NT4. It was created during Windows 2000 development.

What about Vista or 7 x86 with 2000's BOOTVID?

It should work, but I need to download and install x86 version of Vista..

Very interesting.
I understand that you only tested it with an legacy BIOS. Have you tried in EFI mode?
I need to check maybe WinXP x64 will start in EFI mode on ThinkPad X220 with the original Intel graphics driver. WinXP x64 have video handling part problem in EFI mode - WinXP x64 & EFI

I am more interested in how to boot NT5.x in SCREEN mode though (show up a console with version numbers as you shown).

SCREEN mode is a special ReactOS kernel mode for debugging:

In order to see this, you need to boot ReactOS kernel with some debug arguments.

Maybe you want /SOS argument instead - you can try to boot in "Directory Service Restore Mode" (choose in Advanced Boot Options):

Windows Server 2003 with ReactOS bootvid:


I put /sos argument on boot.ini file. definitely works.

In essence, bootvid merely provides the vga interface for the kernel. It is no surprise you can swap them like this. This is because calls to it are hooked through other api's to hide the non-public bootvid functions.

Screenies of WinSrv2k3R2 with XP and 2000 bootvid.dll are coming soon.
It'll take around 15-20 minutes to post the screenies, because it is still downloading and need a few more minutes to install.

Sadly, they're the same...

You can still check for Windows Whistler builds.

[Dz3n]

You can still check for Windows Whistler builds.

And for Longhorn too. But I believe that there are no differences.

I guess there are differences:

I also tried the bootvid.dll files from different versions of Windows and also did not help. Interestingly, the bootvid.dll file from Vista Beta 6.0.5384.4 or Vista Business SP2 work with WinXP x64 but only in Legacy BIOS.

[meweinew]

I am still facing the issue. Did you really find the solution?

Maybe Longhorn's Pre-Reset builds as they were highly similar to XP structure wise.
