Reconnect is the function that occurs when a target selects an initiator to continue an operation after a disconnect.

EEPROM

Electrically-Erasable Programmable Read Only Memory. An inte- grated circuit used to store the host adapter firmware, which allows both mode download and firmware upgrade while in- circuit.

EISA

Extended Industry Standard Architecture. A superset standard of the 8- and 16-bit ISA standard which allows 32 bits of data to be transferred across the bus at up to 33 MBytes/second.

Enhanced Mode

The operation mode of the AHA-1740A/1742A/1744 to take full ad- vantage of the addressing range and register set available under EISA. It is not compatible with earlier revisions of ASPI manag- ers and drivers.

EPROM

Erasable Programmable Read Only Memory. An integrated cir- cuit used to store the host adapter BIOS.

FIFO

First In/First Out. A queuing order in which items are removed from the queue for execution in the same order in which they are placed in the queue. An integrated circuit that buffers data in such a manner that each byte placed in the buffer is removed from the buffer in the same order.

Firmware

The software that controls and manages the host adapter. It is firm as opposed to soft because it is designed into the host adapt- er and cannot be modified by the user.

Host

A microcomputer in which a host adapter is installed. The host uses software to request the services of the host adapter in trans- ferring information to and from peripheral devices attached to the SCSI bus connector of the host adapter.
