32MB Disk Emulator
PROMDISK® is a high performance solid state disk emulator designed to plug
into a standard 32-pin EPROM socket in the BIOS extension address space
of a PC compatible computer. The PROMDISK emulates a fixed disk drive with
capacities ranging in size from 4MB to 32MB using non-volatile NAND Flash
Memory. PROMDISK includes an internal BIOS extension ROM that contains the
Datalight FlashFX integrated Flash file system and ROM-DOS version 6.22
disk operating system.It is fully DOS and Windows compati-ble, allowing
the user to copy and erase files using standard DOS commands.
The on-board BIOS ROM automatically installs the PROMDISK as a bootable
drive C, or the last logical drive when physical drives are present.PROMDISK
can also be configured as the first bootable drive and automatically re-map
physical drives when present.
The PROMDISK can replace a mechanical disk drive in systems designed to
operate in harsh environments, or where weight and size are at a premium.
The use of the PROMDISK in embedded or dedicated applications offers substantial
benefits in overall system cost, performance, and reliability. Since the
PROMDISK operates at bus speeds and is not encumbered by mechanical latency,
the average read/write throughput is increased over that of a typical hard
disk drive. The PROMDISK contains no moving parts, and incorporates low
power CMOS technology to provide the highest reliability with the use of
commercial grade components.
