Wrong BIOS version in VM

[ganesh_patwardh]

Hi,

     If I run 'dmidecode' command from VM it shows wrong BIOS version.  (I have set smbios.reflecthost=TRUE)

    I am using ESXI 5.5 update-2

Hi,

Dmidecode is a tool which collects hardware information from SMBIOS and display it in a human readable format. Dmidecode is available in different flavors of Linux (example: RHEL/CentOS/Fedora). Dmidecode does not scan your hardware, it only reports what the BIOS provides to it. You will  require root privilege to execute dmidecode command. - If you would like to find specific hardware information, then you can use different keywords with dmidecode command.

The supported keywords are bios, system, baseboard, chassis, processor, memory, cache, connector, slot. Remember that Redhat Linux 4 may not support these options/keywords for dmidecode command. So try using these  keywords in RHEL 5 or 6

Hi Umesh,

       Yes I know all the details you have given.

        I have many types of hardware platforms and in most of them I get proper BIOS version inside VM using dmidecode tool (I know how to use it and I have root privilege).

        But on some hardware platforms I get wrong BIOS version (usually 6.00) for example on Dell630 server.
