Well, PCI IDE stands for Peripheral Component Interconnect , Integrated development environment

Industry Standard Architecture (in practice almost always shortened to ISA) was a computer bus standard for IBM compatible computers.

ISA originated as an 8-bit system in the IBM PC in 1981, and was extended in 1983 as the XT bus architecture. The newer 16-bit standard, the IBM AT bus, was introduced in 1984. In 1988, the Gang of Nine IBM PC compatible manufacturers put forth the 32-bit EISA standard and in the process retroactively renamed the AT bus to be "ISA" to avoid infringing IBM's trademark on its PC/AT computer.
