Inge,

Awesome graphic!

That really cleared it up. Did you make any progress on creating a utility to update the SLIC in the HyperV exe?

Thanks.

 

It's working as expected

Just install W7 as "Generation 1" guest and install a valid license



Inge

 

Is it? Hope it helps

The tool is working so far and does always a good job, but the Gen2 implementation is missing



Inge

 

But Gen 2 is only for Win8.x / Server 2012 R2, so no issue there then...

 

Inge,

You do have a utility that adds the SLIC in the exe for Gen1?

 

Hi sebus,

you're right, no issue here but it's worth to mention it

 

Yes, but it inserts only the missing MSDM table and puts the well known SLP1 strings in their
valid range. If I remember (the source is written some years ago), the SLIC/RSDT/XSDT tables
are already present. You just need to overwrite the SLIC table and adjust the RSDT/XSDT pointers.


MSDM table structure:

Code:

Signature[4]
Length[4]
Revision[1]
Checksum[1]
OEM ID[6]
OEM  Table ID[8]
OEM Revision[4]
Creator ID[4]
Creator Revision[4]
Version[4]
Reserved[4]
Data Type[4]
Data Reserved[4]
Data Length[4]
Data (KEY)[29]

Can you help me change the vmwp file that includ dell xp win7 2008R2 2012R2(v6.3.9600.17393)? I have some trouble in my server. Thanks a lot!!!

 

Usually my tool installs the exe, but this should also work:

• Shutdown (don't save) all your guests and open a command prompt (admin privileges required)


Then type:

Code:

01.) net stop vmms
02.) icacls c:\windows\system32\vmwp.exe /save C:\windows\system32\vmwp.acl
03.) takeown /f c:\windows\system32\vmwp.exe
04.) icacls c:\windows\system32\vmwp.exe /grant:r %username%:F
05.) rename c:\windows\system32\vmwp.exe vmwp.old
06.) copy c:\PathToYourModded.exe c:\windows\system32\vmwp.exe
07.) icacls c:\windows\system32\vmwp.exe /setowner "NT Service\TrustedInstaller" /c
08.) icacls c:\windows\system32\ /restore c:\windows\system32\vmwp.acl
09.) del c:\windows\system32\vmwp.acl
10.) net start vmms

You can also put these commands in a batch file and execute it with admin privileges...


Close the command window and restart the VM's - done!


Please let me know if it works...

Inge

 

Thanks! I will take a test tonight(+8:00). I am sure I had not shutdown the VMs when I replace the vmwp file.

 

If you don't restart them, how should they read the new bios?

 

I had restarted some VMs(not all) later. And the restarted VMs need to active. The others is OK.

 

I normally change the VMWP.exe by hand, but tried your DOS cmd's for fun.
They work perfectly and are a lot quicker
