Error code 31 in Windows 2000 environment

[Anonymous]

Hi,

I did install the WinCDEmu in my computer.

Windows XP 32Bit SP3 : Good !
Windows XP 64Bit SP3 : Good !
Windows Vista 32 SP2 : Good !
Windows Vista 64 SP2 : Press F8 key whilst boots and selecting the “Disable Driver Signature Enforcement” boot option every time. then it work correctly.
Windows 7 32Bit RC : never try it.
Windows 7 64Bit RC : Press F8 key whilst boots and selecting the “Disable Driver Signature Enforcement” boot option every time. then it work correctly.
Windows 2000 SP4 : error code 31

Do not work in Windows 2000 environment.
In control painel has a DVD/CD Drives called Virtual CD drive.
It is with error code 31.

PS.
I will pay for digital signature, if I can.
😉

I did not test it on Windows 2000, however, I suppose, that the problem is due to some of API functions not supported by Windows 2000. Could you please perform a simple test?:
1. Try forcibly loading VirtDiskBus driver (net start VirtDiskBus from command line).
2. If the driver loads successfully, skip the next step.
3. Download Dependency Walker from http://www.dependencywalker.com/%5D and open VirtDiskBus.sys with it. Observe, which functions are not provided by Windows 2000 kernel and post them here.
4. Repeat steps 1-3 for BazisVirtualCD driver.
As soon as you provide enough information to pinpoint the problem, I’ll be able to release an update (if it is not related to some key functionality not supported by Win2K).
P.S. Regarding the digital signatures and x64, I’ll soon release an update based on Authenticode technology, that will allow running WinCDEmu on such machines after importing SysProgs.org certificate and enabling “driver test mode” via bcdedit. See the http://wincdemu.sysprogs.org page in one-two weeks.

Thank’s,

I try dependencywalker, and VirtDiskBus.sys has no error.

But BazisVirtualCD.sys has an error at NTOSKERNL.EXE

Ordinal : N/A
Hint : 1405 (0x057D)
Function : _aulldvrm

Anyway,

bcdedit /set loadoptions DDISABLE_INTEGRITY_CHECKS

It’s not work, because KB938194(Windows Update)

[Anonymous]

your meaning [ bcdedit /set testsigning on ] …..

[support]

Yes, bcdedit testsigning on will help after I release a new version with SysProgs.org signature.
Could you please try the following driver on Win2K: http://wincdemu.sysprogs.org/win2kfix/BazisVirtualCD.sys
If it works for you, I’ll include the Win2K build in the next release.

Thank’s,

But it did’t work.

DependencyWolker said “No PE signature found. This file appears to be a 16-bit DOS module.” and “Error: At least one file was not a 32-bit or 64-bit Windows module.”

[support]

Maybe, your browser took the unknown .sys file as a text file and corrupt it. Try the following link: http://wincdemu.sysprogs.org/win2kfix/BazisVirtualCD.zip

Thank’s,

This time it gave to me a pure blue screen. 😀

DependencyWolker said no error.

And blue screen said,
*** STOP : 0x000000D1 (0x07CB4000, 0x00000002, 0x00000000, 0xF5C80D64)
DRIVER_IRQL_LESS_OR_EQUAL
*** Address F5C00D64 base at F5C80000, DateStamp 3d90d765 – Cdr4_2K.SYS

[support]

As the crash is inside Cdr4_2K.SYS, most likely, it is a bug in this driver. For example, it can expect a full SCSI device behind the virtual drive and fail, when it cannot find such device.
Sorry, but it is almost impossible to pinpoint the problem without having debug information for Cdr4_2K.sys. You can try sending a minidump to the authors of this driver; maybe they’ll release a patch.

Thank’s lot.

The Cdr4_2K.SYS is Windows Media Player’s component.
And it can uninstall separately !

For example.
WMP 9 : rundll32 advpack.dll,LaunchINFSection C:winntinfroxio.inf,Uninstall
WMP 7/7.1 : Controlpanel – select uninstall WMP7/7.1 – select “Adaptec CD Creater plugin”

In my case WMP9 was installded, and I was uninstall this module separately, then WinCDEmu run GREATLY!

Anyway,

I tried Windows 7 32Bit RC environment and it run GOOD!

so,

Windows XP 32Bit SP3 : Good !
Windows XP 64Bit SP3 : Good !
Windows Vista 32 SP2 : Good !
Windows Vista 64 SP2 : Next version will run with no F8 key.
Windows 7 32Bit RC : Good !
Windows 7 64Bit RC : Next version will run with no F8 key.
Windows 2000 SP4 : Next version and/or http://wincdemu.sysprogs.org/win2kfix/BazisVirtualCD.zip run Good ! (*1)
*1 : need uninstall Cdr4_2K.SYS.
