Troubleshooting

Item
The EVB is not recognized
Cannot boot from the EVB
DiskOnChip and TrueFFS are M-Systems registered trademarks.
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.
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).
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.
