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.
