dmi in the bios ? what is it?

Specs: win or lin, lots

Hi,

When I update a bios in a mainboard, sometimes I get the option to update the dmi as well.

What the heck is dmi? I understand it can hold more info for the os to get or is the just smbios?

I originally thought that it was part of a verification tool that can with boxes bundled with M$ Windows, but have read that it has effects on linux as well.

Whenever I use a monitoring tool to see all my hardware eg. Everest. It says dmi info cannot be verified, or something of that nature.

I have updated the bios in a toshiba laptop that had a recovery disc that work not work till you modified the dmi back to the original setting. This was done by an utility on the restore disc called chgdmi.exe. One had to retype in the name and model of the laptop to reset it after executing the app.

I have read the section in wikipedia and still am confused. In older mainboards the bios was kind of two parts. The writable and the part you had to change a jumper to write to. Is this the same idea?

Also on the cicero (which essentially has a gigabyte board and some other hardware) I first used a bios from intel (which was wrong but still managed to flash and work,(this was one of my first bios updates). Then I used one from the circero site which also worked, but not until recently I thought that maybe be an update from the bios manufacturer might be the best option and yes it was. Now I can see my sata load on the post screen.

So I was given an option in the last senario (gigabyte update) to update the dmi. So I believe I selected yes.

How do I tell if it was successful? What kind of negative impact can it have if it were wrong/corrupt?

Any help would be great, thanks

The DMI pool is the information kept by the Bios of your current hardware configuration. It's kept in the CMOS. It can sometimes be corrupted by a failing motherboard battery. But hardware changes can also occasionally get it messed up.

Do yourself a favor BACKUP!

How can I check if what I did is good or bad or doesn't matter?
