Booting from Disk

The legacy BIOS boot code Biosboot.exe supports booting from hard disk, floppy disk, USB disk, or any other kind of disk device supported by the target computer's BIOS. To configure a program to boot from disk, simply include a Locate BootCode Biosboot.exe, a Locate BootData, and a Locate DiskBuffer in the application's configuration file. All program entities should be located in RAM regions.

Booting from disk using a legacy BIOS is the simplest boot method. It does not require any ROM or EPROM and applications do not have to be ROMable. Updating and changing applications is easily accomplished by simply overwriting the disk.
