Introduction 

 

1.About This Manual 

This manual provides instructions for the installation and specification of PQI's 

DiskOnModule, DiskOnModule

 is designed for use in PCs, and their respective 

compatible computers. 

 

2.What is DiskOnModule? 

PQI's 

DiskOnModule

 is a storage device based on flash memory technology, 

which emulates an ordinary magnetic hard disk. The 

DiskOnModule

 series products 

provide an all in one module solution for solid-state flash disk. The 

DiskOnModule 

is 

suitable for use in portable  and embedded systems which have limited space and 

power consumption. 

Unlike standard IDE drives, no signal cable and extra, special space is 

required. The

 DiskOnModule

 is a solid-state solution for IDE Hard Disk drive, which 

has no moving parts. That provides a good stability in a moving system.The 

DiskOnModule

 products are also free from extra and special algorithm or some 

firmware driver. Just plug the 

DiskOnModule

 into the IDE slot and play it,users can 

play the 

DiskOnModule

 as same as the Hard Disk Drives. 

The 

DiskOnModule

  family  provides  the  capacities  ranging  from  16MB  up  to 

2GB. In the future, the capacity will be increased up to 4GB.
