BOOTP Configuration Method (default) B-3
Edit the BOOTP Configuration File
The boot-server configuration file,
BOOTPTAB
, is located in the
C:\ABIC\BIN
directory. BOOTPTAB is an ASCII file that looks like:
#Legend:gw -- gateways
#ha -- hardware address
#ht -- hardware type
(1)
#ip -- host IP address
#sm -- subnet mask
#vm -- BOOTP vendor extensions format
(2)
#tc -- template host
#Default string for each type of Ethernet client
defaults5E: ht=1:vm=rfc1048
#Entries for SLC 5/05 processors:
sigma1: tc=defaults5E:ip=12.34.56.1:ha=0000BC1D1234
sigma2: tc=defaults5E:ip=12.34.56.2:ha=0000BC1D5678
sigma3: tc=defaults5E:ip=12.34.56.3:ha=0000BC1D9012
This file contains the information needed to boot the ENI.
You must edit the
BOOTPTAB
file to include the name, IP address, and
hardware address for each ENI you want the server to boot. To edit
this file:
1. Open the
BOOTPTAB
file using a text editor such as Notepad or
Wordpad.
The file contains text that look like this:
#Default string for each type of Ethernet
client
defaults5E: ht=1:vm=rfc1048
These are the default parameters for the ENI and must always
precede the client lines in the
BOOTPTAB
file.
The file also contains a line that looks like this:
#Entries for SLC 5/05 processors:
sigma1:tc=defaults5E:ip=12.34.56.1:ha=0000BC1D
1234
The “#” character defines the line as information, not
configuration data.
(1) 1 = 10 MB Ethernet
(2) Use rfc 1048.
IMPORTANT
Use the sigma1 line as the configuration
template for the ENI.
