Erasable Programmable ROM (EPROM): A semiconductor ROM device capable
of being erased and reprogrammed by the user as often as desired. Once programmed,
the EPROM is a nonvolatile memory that will hold its stored data indefinitely.
Extended Data Out (EDO): A type of DRAM that allows higher memory system
performance since the data pins are still driven when CAS# is de-asserted. This
allows the next DRAM address to be presented to the device sooner than with Fast
Page Mode DRAM.
Extended Memory: The RAM address space, in a computer so equipped, above the 1
MB level.
External Device: A peripheral or other device connected to the computer from an
external location via an interface cable.
 F 
Fast Page Mode (FPM): A “standard” type of DRAM that is lower performance
than EDO but is less expensive.
Fixed Disk: A hard disk drive or other data storage device having no removable
storage medium. Fixed disk storage devices use inflexible disk media and are sealed
to prevent data loss due to media surface contamination. Fixed disks generally
provide the most storage space for a given cost when compared to semiconductor,
tape, and other popular mass storage technologies.
Flash Boot Device (FBD): A flash memory device containing the computer’s BIOS.
In the EPC-30, a 512 KB Intel 28F400BV-T semiconductor flash memory containing
the system and video BIOS images, the BIOS initializing code and the recovery code
which allows self hosted reflashing.
Flash Card: A removable read/write flash storage device closely resembling a credit
card in size and able to hold several megabytes of data.
Flash Memory: A fast EEPROM semiconductor memory typically used to store
firmware such as the computer BIOS. Flash memory also finds general application
where a semiconductor non-volatile storage device is required.
Flash Recovery: See BIOS Recovery.
Flash Update: See BIOS Update.
Force Update: See BIOS Recovery.

Gigabyte (GB): One billion bytes; 2

Hang: A condition where the system microprocessor suspends processing operations
due to an anomaly in the data or an illegal command in the instruction set.
