2.3.2.2Running DbFlash.exe

Make sure that both DBFLASH.EXE and DOS4GW.EXE are in the same directory or environment path. The user must specify the flash block to update and the new image to use. The following will flash image ‘NewRomImage.bin’ into block zero (0) of the 21554 expansion ROM. During the next boot of the PC, the BIOS will find this image in the ROM.

Dbflash /b0 NewRomImage.bin

If the BIOS has a PCI compliant Expansion ROM header, the image is loaded and executed by the system BIOS during POST. For more information, read the PCI Local Bus Specification Revision 2.3.

Dbflash /bx image.bin

Where: Dbflash

/bx

image.bin

Runs the dbflash utility from the current directory.

Specifies the starting block to write the program into.

If x=e then all blocks will be erased.

This is the name of the file to load. The file must be in the current directory or folder. If image is larger than 1 block, the program will continue into the next block until the entire image is loaded.

Note: Any other application software is the responsibility of the user.

2.4Installation Procedure

Figure 2 on page 8 shows the location of components referred to in this section. Follow these steps to install the DE1B55503:

1.Power down the host system that will contain the DE1B55503.

2.Place the motherboard and the associated support devices on a work bench to allow testing of the DE1B55503.

3.Before applying power, verify that the DIP switches are set to the desired positions. (The DIP switch positions are only read during system power up.)

4.Insert the card edge of the DE1B55503 into a PCI slot.

5.Load up the DE1B55503 with the PCI option cards to be tested. Either the 5V or universal type PCI cards can be installed but card types cannot be mixed. There are two (2) provided slot
