The DiskOnChip is a new generation of high performance single-chip Flash Disk. It provides a Flash Disk in a
standard 32-pin DIP package.
This unique data storage solution offers a better, faster, and more cost-effective Flash Disk for Single Board
embedded systems. The DiskOnChip provides a Flash Disk that does not require any bus, slot or connector.
Simply insert the DiskOnChip into 32-pin socket U16 position on the CPU board. It is the optimal solution for single
board computers, it is a small, fully functional, easy to integrate, plug-and-play Flash Disk with a very low power
consumption.
The DiskOnChip is fully tested and formatted before the product is shipped.
(1) DiskOnChip Hardware Installation
Step 1:
Make sure the target platform is powered OFF
Step 2:
Plug the DiskOnChip device into the U16 socket. Verify the direction is correct (pin 1 of the DiskOnChip
is aligned with pin 1 of the U16 socket)
Step 3:
Power up the system
Step 4:
During power up you may observe the messages displayed by the DiskOnChip when its drivers are
automatically loaded into system’s memory
Step 5:
At this stage the DiskOnChip can be accessed as any disk in the system
Step 6:
If the DiskOnChip is the only disk in the system, it will appear as the first disk (drive C: in DOS)
Step 7:
If there are more disks besides the DiskOnChip, it will appear by default as the last drive, unless it was
programmed as first drive.
Step 8:
If you want the DiskOnChip to be bootable, copy the operating system files into the DiskOnChip by
using the standard DOS command.
