Introduction

DiskOnChip
PCI Evaluation Board (EVB) provides you with a quick and easy way to evaluate the
DiskOnChip in platforms with a PCI extension slot. The EVB is a useful tool for designers who need
to evaluate, program, duplicate or test the DiskOnChip, even before their target platform is available.
Once installed, the DiskOnChip PCI EVB can be accessed as an additional disk drive or as a boot
device.
AMD's DiskOnChip products are high-performance single-chip flash disks that provide full hard
drive emulation in all major operating systems and platforms. This unique product offers a complete
data storage solution for applications in which mechanical hard drives cannot be used such as
embedded systems, Internet access devices, network computers, mobile systems and so on. The
DiskOnChip 8MB provides superior performance through a true 16-bit bus interface and offers
security enabling and data protection features.
