Micro Channel Architecture
Micro Channel Architecture (architecture)(MCA) IBM's proprietary 32-bit bus, used inhigh-end PS/2 personal computers. Micro Channel isdesigned for multiprocessing. It eliminates potentialconflicts that arise when installing new peripheral devices.MCA is *not* compatible with either EISA or XT bus architecture so older cards cannot be used with it.
As with the ROM BIOS in the first IBM PCs, figuring outthe Micro Channel's secrets has been an arduous task ofreverse engineering ever since the PS/2 line was announced.Consequently, the MCA has never become as wide spread as thecompeting EISA standard.AcronymsSeemotorcycle accident |
