Add support for selecting harddrive order in boot menu.

Save ATA harddrive model name so that it can be shown from menu.
Minor - use "ata0-1" not "ata0 slave".
Fill fdpt info based on BIOS drive id - not the controller id.
Add BCV support to IPL code.
Use "BCV" system to set harddrive order (for both ata and option roms).
Also, don't show floppy/cdrom in boot menu if no drives found.
