re: How to enable Intel VT on Acer Aspire 7720G laptop

.NetRolller 3D — Tue, 10 Aug 2010 00:36:12 GMT

Hi Guys! I've prepared a modded BIOS for the Acer 7720 (also works for the 5720) that allows access to the VT and related options through a menu in BIOS Setup. The only downside is that the Information menu had to be removed to make way for the new menu. You can find it @ ifile.it/.../icl50-1.45-slic21-advmenu-v2.fd - after installing this BIOS, look for Intel VT in the "Advanced" submenu of "BIOS Tweaks".

Hope this helps,

Hi Girish,

I forgot to make it explicit that this is for SharePoint 2007 only, and not for SharePoint 2010. But thanks for the info, I'll take a look at it for SP2010.

Can't you just use powershell?

Hi Donald,

thanks for pointing me to that information. I took a look on how it was implemented and unfortunately Microsoft didn’t fix the .Net framework on SPN generation. The default implementation is still not using high ports. So everything that uses the System.Net.WebRequest (like the RSS Viewer webpart, old style asmx webservice proxies, custom .net code to fetch web data, etc.) by default will not use ports in the spn generation. However there is a way to work around this: the System.Net.AuthenticationManager has a CustomTargetNameDictonary that is used to map URIs to SPNs. The GetComputeSpn method of System.Net.AuthenticationManager will first check the dictionary for an entry and use that spn, before it computes a spn (without port number). So the work around is to fill that dictionary with your custom SPN (for instance with a different service class or using a high port) for a specific URI, before doing a webrequest to that URI.

SharePoints Shared Services (SSP) like Excel Services, Search, etc. uses above work around mechanism combined with a new SPN Service Class: MSSP (format: MSSP/<host:port>/<SSP name>), to be able to use SSPs on high ports with Kerberos. (See also technet.microsoft.com/.../cc263449.aspx for more information on this MSSP spns)

So yes, it is fixed for SharePoint to use Kerberos with SSPs on high ports. (SSP only, this doesn’t fix normal web apps on high ports using Kerberos). But this isn’t fixed for the whole .Net framework. The only possible exception I haven’t tested yet is WCF. From reflection it looks like certain WCF scenario’s are also using this workaround. Looks like a nice investigation opportunity for a next blog posting ;-)

Nice article! I agree on not using non default ports, although it should be fixed in .Net Framework 3.5 SP1. See blog of spencer www.harbar.net/.../crawling-kerberos-web-applications-on-non-default-ports.aspx

After executing each single step described, we finally were able to activate the missing Intel VT-x mode on an Acer 7720G notebook ;-))

Exactly how do you execute step 8? installed phyton, and downloaded the vtenable.py file, but if i just double click it nothing happens. (a small cmd window pops up for a split second before disappearing, and no change in the directory)

Finally done it. There is few more steps before to flash the new bios.

1. Edit the platform.ini section [Option] and modify

"Flag=0" to "Flag=1"

2. run InsideFlash.exe with as administrator

3. Now there is Option Button there. Press it!

4 In "Option" TAB choose the new bios file

5 In "ROM protection List" TAB set check "Flash All"

6 Start the overwriting

Now should work.

Good luck!

I try to fix 7720g with Intel T7500 - it didn't work.

Could someone who enabled VT send me vtenable.py?

Thanks.

I was fiddlering my own sharepoint instances and found this healthScore header - and it had me puzzled. Thanks for doing the leg work - keeps my reflector closed for at least another day or two.
