Booting the Tri-M MZ104 and the COTS PC with a Flash IDE Drive
The x86 CPU powers the final two targets: the Tri-M MZ104 and COTS PC. These targets boot from and use Flash IDE drives. This section presents the flash IDE technology selected and shows how to compile the kernel, create the target root filesystem, and prepare the flash drive for booting.
