DiskOnChip PCI EVB User Manual
8 Troubleshooting
Item Action
Make sure DiskOnChip is formatted.
Another device may be using the same memory window.
Remove unnecessary cards 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.
Are you working with an 8-bit device in 16-bit mode bus? Check
the J3 and J5 settings.
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 DiskOnChip and load its driver.
The EVB is not recognized.
Your system may have a reset signal that is shorter than the
standard reset signal defined in the PCI design specifications.
The DiskOnChip PCI EVB is not recognized by these systems.
Make sure you have placed the OS system files on DiskOnChip
(In DOS – Format D: /s).
I can't 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 DiskOnChip.
