DATA ADVANTAGE BOOT SEQUENCE
The following sequence occurs when the Data Advantage VME Chassis are booted (via power cycle, reset key,
or reboot command):
Step
CAP Board
VCOM24 Board(s)
1.
Board Initializes Itself.
The FAIL, STATUS, and SCON LEDs
are lit for 1 second.
FAIL is turned off, STATUS flickers, and
RUN is lit for around 10 seconds.
RUN flickers.
If the hard disk has never been formatted,
or has been replaced, a prompt will
appear asking if a high level format
should be performed. If the response is
'Y', a high level format will begin.
Board Initializes Itself.
SYSFAIL and all of eight small LEDs
flash on for 1 second.
The RUN LED is lit and all others are
turned off for around 10 seconds.
The sixth LED is lit to indicate that the
VCOM24 Board has posted an interrupt
to the CAP Board.
2.
If present, LOADER.SX is copied from
the floppy to the hard drive.
The LOADER.SX from the hard drive is
loaded into RAM and executed.
If present, DACAP.SX and WNI.SX are
copied from the floppy to the hard drive.
3.
Board extends multiprocessor OS across
all boards.
Board joins the multiprocessor OS.
The small LEDs walk from 0 to 7 and
back to indicate that the board will accept
a download.
4.
The Loader parses the SYSTEM.TXT
file for the board types and application
load file pathnames. It then copies the
applications to the CAP Board and
VCOM24 Boards.
Board accepts download.
When the download completes, the board
number (2 through 3) is displayed on the
small LEDs. If the board isn't
configured, they sequence indefinitely.
5.
A banner is displayed on the Diagnostic
Terminal.
SYSTEM.TXT is parsed a second time.
/cnfg/system.rpt is built with the results.
Phase 1 verifies each command and its
parameters.
Phase 2 verifies that the commands are
valid for the board type and that all
required commands are present.
Phase 3 supplies default values as
necessary.
Phase 4 does a complete check of the
configuration.
Phase 5 builds the internal routing tables.
Board waits for parser to complete.
On configured boards, all small LEDs are
lit.
