D25 BootROM
BootROM software is stored in replaceable EPROM. The BootROM
contains:
•
pSOS operating system software
•
Device drivers to interface the pSOS with the system hardware and software
•
Diagnostic tests required to verify the integrity of the D25
•
The monitor interface for examining the system in a non-operational mode
•
Startup code that verifies and initializes the application software
•
A stand-alone system for low-level maintenance and troubleshooting.
−
All of the code in the D25 BootROM is duplicated in the standard Base
application load. When the D25 is operating the BootROM applications, it
does not refer to the applications in the FLASH code, and vice versa.

on the rear of the D25
3.
Over a LAN or serial PPP connection, as a TELNET session from a
remote network station
