From the hard drive itself. Bios query all IDE devices and get the
model, type, and size.

The bios asks the hard drive, during the beginning of the boot up.
This is a very basic explanation.

BIOS issues the IDENTIFY DEVICE command.
You can find the description in ATA/ATAPI specification. (www.t13.org)
