Each line of BOOTCONF.SYS should be entered using the following format:
0x[network],[node]=[image file name]
where if the network number is 1, the node address is 00A024D6055F, and the boot image
filename is WRKSTN2.SYS, then the appropriate syntax is:
0x1,00a024d6055f=wrkstn2.sys

E : : The first character of a BOOTCONF.SYS entry is a ZERO (not the letter O).
Although most node addresses are 12 digits long, you do not need to
include the leading zeros.
To avoid confusion and problems related to network numbers you should enter wild cards for
the network number followed by the node address which can be obtained from the NIC. To
use wildcards insert eight question marks (?) instead of the network numbers as follows:
0x????????,[node]=[image file name]
Entries in this format must be generated for each PC that needs a boot file other than the
default NET$DOS.SYS.
Wild cards can also be used for the node address. This allows several workstations to use the
same image file. A common use of wildcards in the node address is to use question marks for
the last 6 characters of the address. This will allow all NICs from the same manufacturer to
use the same image (the first 6 characters of the node address indicate the NIC
manufacturer). The placement of the wild card entries is important; they should be at the
end of the file so they do not override any specified addresses. In Figure 21, all NICs that
have the first 6 characters
00104B
will use SALES.SYS, except for
00104B267345,
because it
has it’s own entry above the wild card entry.

: To find the PC's node address, check the MBA boot screen or use the
configuration program that comes with your NIC.
You may put comments on each line entry in BOOTCONF.SYS, as long as there is at least one
space separating the boot image file name and the comment. In general, it is a good idea to
keep comments reasonably short, as MBA must scan through them. Too many comments
may delay the PC's boot procedure.
