Re: U330 bios doesn't enable virtualization techonology mode?

I just flashed my bios and as you, i dn't Vt enabled, while i was parsing the ini file of the insyde flash utility i noticed some interesting parameters,

it looks like that some part of the bios can be protected and so not allowed to be overwrited by flashing it. Our area where the vt flag is located could be part of a protected area and so nothing happen. could some have a look a the file too to give his feeling.

i'm gonna try to flash my bios by soe other way

in the platform.ini there is a [ForceFlash] section with ALL=

according to the comments, if ALL=1 it will flash all rom part, if it set to 0 " Resverd all protect areas." as written ..

does it mean reserved ?

by default in the lenovo bios upgrade package it is set to 0, maybe if we set it to 1 we could have our VT enable, but what else could be erased ... i don't know ...

i'm not that at ease with linux, but someone could try by using FLA**bleep** with a usb key because if have no idea how to use it

Securable will show you that everytking's OK with VT even when VT is diasbled on BIOS.

Best way to check if Vt is enabled in BIOS is to try install 64-bit OS on virtual machine.

Yep the ALL=1 option did the trick. I've now got VT-x enabled on my U330. As far as I've read, the current settings (which are modified by the patch) are stored in a different place than the actual BIOS image.

 

root@hermes:~# modprobe msr
root@hermes:~# ./msrmagic
MSR Magic 1.0 (C) 2009 George Styles www.georgestyles.co.uk

cpud 0 is locked ON :)
cpud 1 is locked ON :)
Device /dev/cpu/2/msr does not exist. Either we have run out of processors, or the msr kernel module is not loaded

 

I've successfully launched the Ubuntu 9.10 64bit virtual machine in VirtualBox under Linux.

Could anyone make a revised step-by-step instruction?

 

Thanks o0TMS0o for your input on this :)

 

Please note: I've also tried FLASH IT under FreeDOS, but it didn't work (it didn't flash the settings part).

Ricky119,

 

We can inquire further, but the IdeaPad product line does not support VT presently.  As it is not marketed as specifically having this feature, this will likely be seen as a future requirement rather than a bug to fix.

 

Best regards,

 

Mark


 

 

Right. I don't exactly know why the IdeaPad product line does not support VT, while it does. On notebooks having a suitable processor (like U330 with it's P8400), it's only a matter of _ONE_ setting in the BIOS.

 

I'll explain it: Lenovo Ideapads use InsydeH20 BIOSes, which are actually mini operating systems, with ready to use routeines and options. The vendor does some tweaking, adds some custom functionality, but usually only chooses which options are to be enabled, disabled, which should be presented to the user in the settings menu and which should be hidden. In case of VT on Ideapads, the BIOS already has the support (appropriate methods and code routines), but Lenovo had DELIBERATLY hidden the option from the settings menu.  The whole patching thing actually changes the hidden setting from value "Disabled" to "Enabled".

 

Why did Lenovo hide the option? I fail to see a reason, other to hamper the functionality on purpose to sell the product as a "consumer" grade one. This policy will certainly backfire in Lenovo's face once normal users start being interested in virtualization thanks to Windows 7's XP Mode.

It's really a good news that neuro-pl finally got VT work on U330 !!!!!!!!!!!!!!!

As fare as I know, there are many problems with U330 such as VT, battery, 'Intergrated Graphics Only', poor driver etc. Lenovo just ignores these problems. I think I will buy  another brand of laptops in the future.

 

Is it possible that Lenovo will release an BIOS update which add the VT support the day windows 7 retail?

Lenovo had never advertised that U330 supports VT, so you should not accuse them they are hidding something. If you expect from a consumer line such as IdeaPad that it will suit power users, then I think you are mistaken. Anyway, I wonder what problems will appear after you have changed the BIOS to an unauthorized version.
