@Pramod:

You can type this at the command prompt:

wmic bios get /format:value|find "SerialNumber"

It looks like Systeminfo is only returning the first line in HKEY_LOCAL_MACHINE\HARDWARE\DESCRIPTION\System\SystemBiosVersion, which can be incomplete.

For example, on one of our Dell Optilex 745s, that registry value is:

"DELL – 15
Phoenix ROM BIOS PLUS Version 1.10 2.6.3
Phoenix ROM BIOS PLUS Version 1.10 2.6.3
Phoenix ROM BIOS PLUS Version 1.10 2.6.3"

Which is a multi-string value.

Systeminfo only shows "DELL – 15", which isn't very helpful.

A more complete query of BIOS information can be done via WMIC.

At the command prompt, type:

wmic bios get /format:value|find "SMBIOSBIOSVersion"

The pipe command (|, above the Enter key) redirects the output from the wmic bios get /format:value command to find, which then filters it and shows only the line(s) that match SMBIOSBIOSVersion (the find command is case aware, meaning the correct capitalization is necessary to return a match).

That last command returns the following on the Dell machine in the example above:

SMBIOSBIOSVersion=2.6.3

To see everything in the Win32_BIOS WMI class, just remove everything after value, such as:

wmic bios get /format:value
