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.
