I have a Ideapad S12 model 2954 Indows xp 2GB
My latop got the rootkit Mebromi
Unforntunately Lenovo use Phoenix - Award BIOS, only bios affected by that pest
I try everything remove hpa, dco on dard disk and low level format under linux CD live
It come again, Recovery key is un operational.
Only hope is too reset bios (actually I had a password but seems not to bee effective)
Howeve only update bios is for Win XP since only Linux or Win 7 64 bit are not affected by this virus it is a pity to get such bios update without an USB - Ds boot solution.
I have also a Lenovo X61 at work affected by the same pest.
The rootkit pass by a pendrive. I format it but the virus was inside the firmware and format do not remove it and pass from one computer to the other. All my SD cards and back up usb hard disk are contaminated. They seem to work ok to pass the pest and one day you find than partition are gone....
I was able to reset the bios using PFlash16.dos command renaming the bios file and using Hiren CD and DOS option (I took the file reading the iso with izarc and copy to USB drive). The ISO CD was useless since the driver inside could not see external CD. This BIOS update CD would work only with the optional expanded bay. I took 3 days to discover how to do it because the ISO boot CD was really uneffective, Lenovo should use better DOS emulator, look at the one use on Hiren CD than can load USB cd drive. Note than you have to remove the Hard disk before to update the BIOS. The virus cause also some problem in DOS, bat fiie desapear and I have to run the command manualy with Pflash16 .exe unde dos.
Here some usefull information
To get rid of it twould need to flash the hard disk driver to got rid of it fortunately with Ubuntu 64 bit or Win 7 64 bit the computer work ok. For the Ideapad 32 bit I am not able to find a solution myslef
Removing HPA and DCO could not get rid of the pest.
The best way to know if you are ok is to use any Linux Live CD and check than under Gparted you do not have a 1mB hidden partition, this partition is impossible to remove since it is an overlapp problem cause by Bios and firm,ware.
To remove you need an frimware update under another PC, or with a clean bios.
On the X61 It seems o work, but on the Lenovo Ideapad I am stuck because not Bios update is possible except on Window but window is not possible to use because it is infected before the boot. I try also to use a BartPe live CD.
However the battery driver is unloaded. The Bios updater do not permit to update without a battery of 20% ore AC adapter this means than it is not possible to do. I try to add the driver battery.inf from the window under my back up harddisk and to put all battery driver cmbatt.sys batt.sys under the tmp dirver of Hiren CD using drvload.exe run command in CMD.
I beleive than my last hope is a DOS BIOS update release from Lenovo or try to get a new Bios chip.
In that case , I beleive I have to sent back the computer out of warranty for such repair.
I hope than the week I lost to repair my Lenovo notebook could be usefull to thers and than Lenovo could improove theri BIOS Upgrade.
If anybody could have other solutions I am ready to follow anuother part...
