IdeaPad Y430 and Intel VMX [SOLVED]

2008-12-13, 11:22 AM

Hi, I've recently purchased Lenovo Y430 with Intel P8400 2.2Ghz processor.   

I use Gentoo Linux X86_64, though I have Vista installed. 

One of the main criteria was the support of Virtualization extentions, which my Intel P8400 has.

 (# cat /proc/cpuinfo shows the "vmx" flag)

 

When I tried to use Kernel Virtual Machine (Linux KVM), modprobe kvm-intel said:

"kvm: disabled by bios"  

Some vendors disable kvm by bios, but left an option in the bios to enable it.

I didn't found one in my Lenovo.

 

 

So I'm disappointed and surprised.

_WHY_  does Lenovo need to disable virtualization extentions by bios?

Can any bios update be made so bios can enable vmx?

If no, are there any bioses with such an unlocked option?

If no, are there any tools to enable vmx instead of the bios? 

 

Thanks.

Here is another vote for allowing vmx to be enabled.  Virtualization is used by many power home users today and not being to enable vmx is extremely disappointing.  I am extrememly happy with my Y430 except for this.

 

It seems fundamentally wrong to advertise that a computer ships with a certain processor and then to disable features of the processor sited.  I would not have purchased my Y430 if I had known that vmx was disabled; hopefully Lenovo will do the right thing and provide an option to enable the vmx support.

I'm a little upset as well as i still must remote into my old desktop to run vmware..... which is rather unfortunate considering my new y430 blows away my old pc. :((((

All other laptops have Intel VMX enable function in BIOS. Why my lenovo does not ?

I'd like to know official lenovo opinion about it.

 

I liked my Lenovo Y430-1B  but when i find out that it does not have Intel VMX it realy disappointed me.  

I hope they'll fix that problem in next BIOS update.

Different Y430's have different processors.  If you have a model with the T5800, this processor doesn't support VT.

Here's another vote for VTX BIOS support. I posted about this probably 6 months ago and never got a reply. I hope Lenovo sees this thread.

Re: IdeaPad Y430 and Intel VMX

My questions is, has anybody been able to dump the BIOS as a file using AMIs flash utility and tried to modify the BIOS to enable VTX in the BIOS and then flash it to the BIOS chip? I have been trying to dump my BIOS for a while now and have been unsuccessful.

 

Currently I have downloaded AMIs flash utility found here. The BIOS in my Y530 is the Aptio EFI. I have tried the standard AMI flash utility located in the ZIP file, and the Aptio flash utility with the following command line...

 

AFUDOS BIOSDUMP.ROM /O

 

AFUDOS - is the AMI flash utility in DOS form [for both standard AMI and Aptio]

BIOSDUMP.ROM - is the output file name for the BIOS dump

/O - is the command to save the current BIOS to the given file name [the command is the letter "O" not the number "0"]

 

When I tried with standard AMI flash utility, it says that the BIOS is write-protected [sounds reasonable except I only want to read the BIOS to file not write to BIOS from file].

When I tried with Aptio flash utility, it says there was an error reading BIOS flash ID [or something of the kind].

 

I also tried with the Windows GUI based flash utilities and they did not work. In fact, my laptop [bought NEW from Lenovo] has a BIOS flash utility that may have been left installed by Lenovo. It is called WinFlash. Whenever I run the program, it asks me for the new BIOS flash file.

 

Has anyone tried doing any of this? Or does anyone have a BIOS dump for the Y530?
