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

2009-09-28, 13:48 PM

it is not my BIOS, but the procedure to modify yours !!

 

 about the risk, yes it is risky, but many people have already done it one other laptops, acer HP vaio, essentialy and no one has reported failure, and the U330 has a bios shadow features, which I don't know how it works. But it looks like that if your bios cannot load, the recovery bios should magicaly take things in hand and give life again to your laptop,

their is also a procedur here : http://forum.notebookreview.com/showthread.php?t=284686&page=1

that explain how to recovery a bios for an insyde Bios. haven't tried it either

VT enabling (rapidshare archive)

2009-10-05, 13:34 PM

Can you please upload your ZIP archive about enabling VT on Lenovo U330 again? I've upgraded my BIOS using post on http://marcansoft.com/, and everything is done as it was said (bytes difference etc.), but nothng's changed.

Thanks!

here is the file http://rapidshare.com/files/289013507/Procedure_enable_VT.zip.html

 

about testing, you can use some tools to check it, or use virtualbox or vmware to see if the hardware acceleration is supported

may be it's virtual pc bug, but it doesn't see vt enabled. about virtualbox: seems like vt is working (3 vista's are installed simultaneously) and no prompts come, but i'm in doubts.

check the vmware log (or other product) in vm forlder as the VT flag should not been enabled in VM.

Vista 32-bit or 64-bit?

You can install 32-bit systems withoout VT enabled in BIOS.

When you try install 64-bit system without VT you see information "VT support required" (or something like this)

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

2009-10-10, 10:08 AM
Has anyone succeeded in actually modifying your BIOS?

I've tried all the procedures (both from the entry on the blog and in the rapidshare file), created an appropriate image (yes, I've verified it using vbindiff - the appropriate bit is set and the checksum is correct) and tried to flash it using InsydeFlash. The flashing goes well, but I'm getting no VT-x.

In VirtualBox I'm getting: VT-X/AMV-D hardware acceleration has been enabled, but is not operational. (...) Please ensure that you have enabled VT-X/AMD-V properly in the BIOS of your computer.

The log says:
neuro@hermes:~/.VirtualBox/Machines/Ubuntu 9.04/Logs$ grep HWAC VBox.log
00:00:01.456 HWACCM: No VT-x or AMD-V CPU extension found. Reason VERR_VMX_MSR_LOCKED_OR_DISABLED
00:00:01.456 HWACCM: VMX MSR_IA32_FEATURE_CONTROL=1

Whilethe support is enabled in my U330's P8400 processor:
neuro@hermes:~$ egrep '(vmx|svm)' /proc/cpuinfo
flags           : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe syscall nx lm constant_tsc arch_perfmon pebs bts rep_good pni dtes64 monitor ds_cpl vmx smx est tm2 ssse3 cx16 xtpr pdcm sse4_1 lahf_lm tpr_shadow vnmi flexpriority
flags           : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe syscall nx lm constant_tsc arch_perfmon pebs bts rep_good pni dtes64 monitor ds_cpl vmx smx est tm2 ssse3 cx16 xtpr pdcm sse4_1 lahf_lm tpr_shadow vnmi flexpriority

I checked the BIOS by backing it up again using Insyde Flash to see what's going on.  It appears that the changes from my modiefied flash image didn't make it into the BIOS. Any ideas? Maybe the flasher needs some special parameters aside from providing the flash image file?

can you check dmesg output for "kvm: disabled by bios" ? (present if kvm module is installed)

This is the case for standard BIOS w/o VT ... as mine :-(

 

Othewise VT-D (iommu) seems to be managed when add intel_iommu=on as kernel parameters. Strange BIOS !?!
