5 Installing and Configuring the DiskOnChip PCI EVB
When installing the DiskOnChip PCI EVB as a bootable drive in operating systems other then DOS,
make sure to place the relevant systems files on the 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 board plugged in. To suppress this message, choose to install a driver, and select the
DOC_PCI.INF file located in the ‘PCI_EVB’directory of the DiskOnChip software utilities. This
will NOT install a driver but will inform Windows of the new hardware and stop this message from
being displayed at boot time.
When working with the EVB in environments other then PC, you must use the DiskOnChip BOOT
SDK to enable your boot code to access DiskOnChip and load your OS and drivers.
Additional information, scenarios and advice regarding use of the DiskOnChip as a bootable drive is
available in the DiskOnChip Software Utilities User Manual.
5.1 Installing the DiskOnChip as an Additional Disk Drive
DOS example:
1. Mount DiskOnChip(s) on the EVB in the appropriate socket (SODIMM, DIP, TSOP).
2. Insert the EVB into a free PCI slot (make sure your host is powered OFF)
3. Power ON your computer (host).
Note: TSOP devices require formatting before proceeding to step 4 (refer to the DiskOnChip software utilities
manual on our web site).
4. You may now access the EVB as an additional drive.
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 DiskOnChip EVB as a Boot Device (DOS Example)
The DiskOnChip EVB may be used either as an additional hard drive or as the system’s boot device
(drive C:). When shipped, the default settings of the DiskOnChip 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 DiskOnChip EVB is correctly installed as an additional drive.
2. Copy your system files onto the DiskOnChip:
FORMAT D: /S or SYS D: (assuming DiskOnChip is registered as drive D:).
1. Remove your hard drive or type:
DFORMAT D: (or /WIN:segment)/FIRST /S:DOCnn.EXB /UPDATE
a) The /S flag must be used when the /FIRST flag is used. DOCnn.EXB stands for the
DiskOnChip firmware file name.

AMD DiskOnChip PCI EVB User Manual
DiskOnChip and TrueFFS are M-Systems registered trademarks. 8
b) The /UPDATE flag instructs DFORMAT to update the firmware without re-formatting the
flash media –keeping the information on it intact (such as the DOS systems files).
3. Re-boot the system.
After re-booting, the DiskOnChip is identified as drive C.
5.3 Identifying the DiskOnChip in the EVB
There are two utilities that can identify the DiskOnChip chip mounted on the 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 the DiskOnChip.
DINFO provides information regarding the 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 the DiskOnChip
Warning: Running DFORMAT erases all data from the DiskOnChip. Make sure to back up your
data before using this utility.
The DiskOnChip can be re-formatted 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 is the first step to perform before starting
development. It is highly recommended to thoroughly read the DiskOnChip Software Utilities
Manual in general, and specifically the chapter discussing DFORMAT.
6 Additional Software Utilities for the DiskOnChip PCI EVB.
You can use any of the DiskOnChip DOS utilities with the DiskOnChip PCI EVB.Detailed
information can be found in the “DiskOnChip Utilities User Manual”.
6.1 Using PMC Connectors
You may connect this EVB to boards in which the PCI bus is only accessible through PMC
connectors (such as the MCP750 reference board), by using PMC to PCI adapter cards (vendor
supplied). Additional information and links to these products is available in our web site
(www.amd.com).

8 Troubleshooting
Item Action
Is the DiskOnChip formatted?
Another device may be using the same memory window.
Remove cards not required and check your BIOS
Configuration.
Another device may be using the same memory window.
Change the base memory address of the DiskOnChip using
J1.
Are you working with the EVB in Dell, Gateway, or Compaq
machines? The BIOS in all of these machines reserves all
legacy ISA resource for use by PCI cards. Please use a
different machine.
Many BIOSs try to reserve the legacy ISA resource for use
by PCI cards. Changing the BIOS settings can modify this
behavior. Look for a setting that describes “Shared ISA
Memory Space” and ensure that this option is set to enable
the DiskOnChip window in the base address set with JP1.
The DiskOnChip firmware may need to be trimmed to work
with your BIOS. Please refer to the DiskOnChip software
tools manual and read about the various firmware flags in
DFORMAT.
Ensure that pin 1 of DiskOnChip is aligned with Pin 1 pad on
the board. Reverse insertion will render the DiskOnChip
unusable.
If you are working with DiskOnChip 16MB TSOP, disable
the 16-bit operation mode.
Is the driver loaded? When using OSs other then DOS,
follow the DiskOnChip installation instructions for your
specific OS.
The EVB is not recognized
When working with the EVB in non-PC architectures, you
must use the DiskOnChip BOOT SDK (also known as BDK)
to enable your boot code to identify the DiskOnChip and
load its driver.
Make sure you have placed the OS system files on the
DiskOnChip (In DOS – Format D: /s).
Cannot boot from the EVB
When working with the EVB in non-PC architectures, you
must use the DiskOnChip BOOT SDK (also known as BDK)
to enable your boot code to load your OS directly from the
DiskOnChip.

Item Action
Disable TSOP devices soldered
on board –without removing
them.
Use J16 and J17 to disable any TSOP-I and TSOP-II
devices soldered on board the EVB.
Suppressing the “Found new
hardware”message in Windows When the message is displayed, choose to install a driver
and select the DOC_PCI.INF file included with the
DiskOnChip software utilities package, under the ‘PCI_EVB’
directory. This will not install a driver but will suppress the
message.
