1. INTRODUCTION
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.
1.2. Features
The PCI-G EVB includes the following features:
• Support for the current DiskOnChip product line using the second-floor adapter.
• An independent memory window for each device on-board
• Support for 1.8V, 3.3V and 5V VCC core and VCC_I/O
• Variable 8-bit or 16-bit operation
• Support for the DiskOnChip hardware protection option, including the LOCK# signal
• Two fixed memory base address are available for the DiskOnChip second-floor adapter
(using a jumper)
• General DiskOnChip interface connector on both sides of the EVB for more flexibility (only
one can be used at a time)

4. PCI-G EVB BOARD CONTENTS
The PCI-G EVB can support most DiskOnChip form factors. You can also cascade up to four
devices using the relevant adapter daughter board.

4.1. Determining the Base Address
The PCI-G EVB supports two selectable memory base addresses, each residing in a separate
memory address. Table 2 defines the memory table for J4.

* Default factory settings.
4.2. Selecting the Voltage
To determine the voltage supplied to VCC_Core and VCC_IO, use jumpers J1 and J5 as
described in Table 3.

* Default factory settings.
**VREF can be set through VR1 and VR2.

4.3. Locking Protected Areas
The PCI-G EVB supports the Lock feature. When the LOCK# pin on the second floor adapter is
set using a dedicated jumper, the EVB does not allow writing to write-protected areas or access
to read-protected areas, even when the correct password is entered.
4.4. Working in 16-Bit Mode
The PCI-G EVB supports 16-bit operation. When the IF_CFG pin is set on the second floor
adapter, the EVB works in full 16-bit mode, achieving approximately twice the performance
speed.

5. INSTALLING AND CONFIGURING THE PCI-G EVB
When installing the DiskOnChip PCI-G EVB as a bootable drive in operating systems other then
DOS, make sure to place the relevant systems files on DiskOnChip (i.e., execute according to
Section 5.1, then install the systems files and continue with Section 5.2).
In Windows systems, the New hardware found message is displayed each time you boot with
the PCI-G EVB plugged in. To suppress this message, select the option to install a driver, then
select the DOC_PCI.INF file located in the PCI_G_EVB directory of the DiskOnChip software
utilities. This will NOT install a driver, but will inform Windows of the new hardware and
prevent the message from being displayed during boot-up.
When working with the PCI-G EVB in environments other then PC, you must use the
DiskOnChip BDK to enable your boot code to access DiskOnChip and load your OS and drivers.
Additional information, scenarios, and advice regarding using DiskOnChip as a bootable drive
are available in the DiskOnChip Software Utilities user manual.
5.1. Installing DiskOnChip as an Additional Disk Drive
DOS Example:
1. Mount the DiskOnChip second-floor adapter(s) on the PCI-G EVB in the appropriate socket.
2. Insert the PCI-G EVB into a free PCI slot (make sure your host is powered off).
3. Power on your computer (host). You may now access the PCI-G EVB as an additional drive.
Note: TSOP and FBGA devices require formatting before the PCI-G EVB can be accessed as an
additional drive (refer to the DiskOnChip Software Utilities user manual on our website).
When using other operating systems, you may need to first install the DiskOnChip driver (see the
DiskOnChip OS-specific installation manuals).
5.2. Using the PCI-G EVB as a Boot Device (DOS)
The PCI-G EVB may be used either as an additional hard drive or as the system’s boot device
(drive [C:]). When shipped, DiskOnChip default settings cause it to be installed as the next
available drive. This will typically be drive [D:] if the system already includes another drive. To
convert it into a bootable DOS drive, perform the following:
1. Boot the system and ensure that the PCI-G EVB is correctly installed as an additional drive.
2. Copy your system files to DiskOnChip by typing FORMAT D: /S or SYS D: (assuming
DiskOnChip is registered as drive [D:]).
3. Remove your hard drive or type DFORMAT D: (or /WIN:segment) /FIRST
/S:DOCnn.EXB /UPDATE. Observe the following rules:
o The /S flag must be used when the /FIRST flag is used. DOCnn.EXB stands for the
DiskOnChip firmware file name.

9 User Manual DiskOnChip PCI-G Evaluation Board 02-UM-0704-00
o The /UPDATE flag instructs DFORMAT to update the firmware without reformatting
the flash media, keeping the information on it intact (such as the DOS systems files).
4. Reboot the system. After rebooting, DiskOnChip is identified as drive [C:].
5.3. Identifying DiskOnChip on the PCI-G EVB
There are two utilities that can identify the DiskOnChip unit mounted on the PCI-G EVB. You
can use DINFO when the drivers are correctly loaded (indicated by the sign-on messages
display). If the messages were not displayed, use DINFO>DIRECT to search for DiskOnChip.
DINFO provides information regarding DiskOnChip size, amount of physical flash used, number
of flash devices inside DiskOnChip, drive letter occupied by DiskOnChip, firmware version, and
so on.
5.4. Reformatting DiskOnChip
Warning: Running DFORMAT erases all data from DiskOnChip. Make sure to back up your
data before using this utility.
DiskOnChip can be reformatted on-board using the DFORMAT utility. The DFORMAT utility
can be used whether or not the device was recognized by the system and assigned a drive letter.
Assuming DiskOnChip is located at address 0xC800, the format command is:
DFORMAT /WIN:C800 /other flags
After running DFORMAT, you must reset the system to allow the changes to take effect.
Important: Correct initialization of your DiskOnChip must be performed before starting
development. It is highly recommended to thoroughly read the DiskOnChip Software Utilities
user manual in general, and specifically the chapter discussing DFORMAT.
