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.

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.

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".

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).
