Operations and Installation

MSKROM.EXE an executable utility for programming the SROM.

The software diskettes are standard 3.5 inch floppy disks. Follow the installation procedure printed on the inside of the shipping package. Be certain that the target system meets the minimum system requirements.

2.3.1Programming the SROM

To program the SROM on the DE1B55503, use the MKSROM.EXE utility. Use a text editor to create an ASCII data file.

MSKSROM file.dat

 

Where: MSKROM

Executes the MSKROM utility.

file.dat

Specifies the file to load into the SROM.

To program a blank SROM:

1.Set SW1 and SW2 to “down” during initialization of the system.

2.After the system initializes, toggle SW1 to “up”.

3.Use the MKSROM.EXE utility. For example:

mksrom.exe sromfile.dat

4. Set SW2 to “up” position and reboot system.

Table 7 shows the two SROM enable and lockout switches.

2.3.2Programming the Flash ROM

Dbflash.exe is an MSDOS based program that allows the flash ROM attached to the 21555 to be erased and updated with new images. When dbflash.exe is run on a system that has a 21555 installed on the PCI bus, the program will scan all the PCI buses looking for the 21555 component. When found, the program will identify the 21555’s PCI location and start the update process that was selected on the command line.
