Title: Computer <grumble>
Post by: Serious on April 28, 2019, 09:06:53 AM
Strange problem. MSI Z87-G43 mobo kept losing the drives. Wouldn't boot, not even to a USB stick.  That seems to have been the MSI speed boot.

When I managed to get into Bios all the drives missing. Took a couple of weeks to get that far.

Replaced CR2032 battery... Cost of new Kodak one 12.5p (8 batteries for a pound). Why do they have to put the battery right under the graphics card slot?

<Homer Simpson> Doh!

Strange that it wouldn't simply redetect the drives every boot, is it a EUFI BIOS?

Yes, it's EUFI. MSI put in a special fast boot option that seems to ignore the USB and doesn't check what drives are attached. It seems to store detected drives in a look up table or similar option and refers just to that.

That saves a few seconds on boot up as it avoids spinning up/checking the actual drives. When working properly it's often got Windows running before I've got an image on the monitor. But, if the battery has failed, it starts up, goes to the look up table and, finding nothing, falls through with a message to insert boot drive.

Seems to be working fine now.
