This contains a list of boot images,
each separated by the ';' (semi-colon) character.
The following provides a syntax for parsing a single
boot image list item.
<device>:[filename] | <URL>
<device> can be (but not limited to):
flash, bootflash, slot0, rom, C
The transfer protocol used in the <URL>
can be (but not limited to):
tftp, ftp, rcp, mop.
The following is en example containing two boot image
names:
disk0:c7100-ik2s-mz;tftp://dirt/c7100-ik2s-mz
If the filename is not specified, then the
first file on the <device> will be used.
If the last two characters in the returned value
are ';+' this indicates that additional boot image
items are configured on the device but can not
be returned because the maximum string size limitation
would be exceeded.
For example:
disk0:image1;disk0:image2;+
ConfigRegisterValue
string
An Integer containing the value of config register.
The definition of individual bits from right to left
when set are as follows:
00 to
03 Boot Fields(Refer below for
explanation).
04 to
05 Not Used.
06 Causes system software to ignore the
contents of NVRAM.
07 Enable the original equipment
manufacturer (OEM) bit.
08 The Break function is disabled.
09 Not used.
10 Broadcast based on 0.0.0.0 IP address.
11 to
12 Defines the console baud rate as below:
Bits 11 & 12 unset: 9600 baud(default),
Bit 11 set & 12 unset: 4800 baud,
Bit 11 unset & 12 set: 1200 baud,
Bit 11 set & 12 set: 2400 baud
13 Boots default Flash software if
network boot fails.
14 IP broadcasts do not have network
numbers.
15 Enables diagnostic messages and ignores
the contents of NVRAM.
Meanings for different values of Boot Fields
(Bits 00 to 03) are explained below:
Value(in hex) Description
------------ -----------
00 On powerup or reload, the system
remains at the ROM monitor prompt
(rommon>), awaiting a user command
to boot the system manually by means
of the rommon boot command.
01 On powerup or reload, the system loads
the system image found in onboard
Flash memory.
02 to On powerup or reload, the system loads
0F the system image specified by
ceExtSysBootImageList.
It tries to boot the
image in the order in which
the image names are entered in
ceExtSysBootImageList. If
it cannot boot any image in the
ceExtSysBootImageList, it
stays in ROM monitor mode.
