1. I
NTRODUCTION
The DiskOnChip PCI-G Evaluation Board (EVB) provides a quick, easy way to evaluate the
DiskOnChip in platforms with a PCI extension slot. The PCI-G EVB is a useful tool for
designers who need to evaluate, program, duplicate or test DiskOnChip, even before their target
platform is available. Once installed, the DiskOnChip PCI-G EVB can be accessed as an
additional disk drive or as a boot device.
M-Systems’ DiskOnChip products are high-performance, single-chip flash disks that provide full
hard drive emulation for all major operating systems and platforms. This unique product line
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 and mobile
systems. DiskOnChip provides superior performance through a true 16-bit bus interface, and
offers security-enabling and data-protection features.
1.1. Supported
Devices
The PCI-G EVB General DiskOnChip interface connector, in combination with the relevant
second-floor adapter, supports the DiskOnChip product line.
A TrueFFS driver is required to work with any of the DiskOnChip products. TrueFFS is natively
supported by every major OS, such as Windows CE, Windows 2000, QNX, and VxWorks. The
latest TrueFFS drivers can be obtained from M-Systems for these operating systems and others,
such as DOS, Linux, pSOS and NT Embedded. For other environments (including OS-less) the
TrueFFS Software Development Kit (SDK) can be obtained. When using DiskOnChip as the
boot device in a non-x86 environment, M-Systems’ Boot Software Development Kit (BDK)
package is required. Contact M-Systems regarding availability for both packages.

•
Support for the current DiskOnChip product line using the second-floor adapter.
