They must jump through the irrational and expensive hoops of the FDA, and patents are only 20 years (compare with corporate copyright of 75 years). This makes them pursue only blockbuster and knockoff drugs. Stuff for chronic diseases you're going to buy for years.
The boot device is the device from which the operating system is loaded. A modern PC BIOS (Basic Input/Output System) supports booting from various devices. These include the local hard disk drive, optical drive, floppy drive, a network interface card, and a USB device.
There are several possible types of boot loaders and ways for the BIOS to obtain them. A. A boot loader stored in the first sector of a hard disk, the Master Boot Record, or MBR. This may be GRUB or LILO or yaboot or others. B. A boot loader stored on some other storage device, such as a CDR or USB flash drive. C. A boot loader which uses the network, such as the Pre-Execution Environment (PXE). This code is normally stored on a ROM on the networking card itself. The need for the initial parts of the bootloader code on the first part of a storage medium explains why some hard drives are 'bootable' and others are not. The job of the boot loader is to begin the next phase, loading the kernel and an initial ram disk filesystem.
