Lenovo M90 BIOS Failure

Hi.

 

I would like to know is there a method to recover the BIOS of Lenovo M90 5474?

 

As in will AMIBOOT.ROM method with CTRL + HOME work on this Machine?

 

Or Is the a Boot Block Recovery method which don't need to unscew the machine?

 

Hope to get a reply ASAP.

 

Thank-You.

Re: Lenovo M90 BIOS Failure

Hi.

 

is this the correct ISO image for Boot Block Recovery?
http://download.lenovo.com/ibmdl/pub/pc/pccbbs/thinkcentre_bios/5jj956usa.iso 

 

I have also notice that the System is like keep loading the Disc drive when i power up.

 

So i just need to download and burn the CD from Lenovo BIOS page, put it in and let it load?

 

I have not Change the Jumper Yet, But it seems like it is looking for a BIOS from the DVD drive.

So i just need to put in this ISO CD to it and it will start recovering?

Problem solve.

 

Manage to Restore the BIOS via Boot Block Recovery.

 

Now working fine, but SLIC 2.1 activation is gone.

 

Windows 7 now become not genunie.

 

Need to manually type the key paste on the casing.

 

But is there a way to restore back the SLIC 2.1?
