Configuring Terminal Start-Up Resources
In a network-boot environment, the client and vendor identifiers are not modifiable
by the user.
The terminal provides the ability to change the Client ID, Vendor ID, and Hostname
fields consistent with the RFCs. The default Vendor ID is Compaq-T1500. The
default client ID is the MAC address with a key (consistent with the RFC
specifications). The default hostname is the letter "t" followed by the last 6 digits of
the MAC address. Hostname is not exported by default, but the other two are.
Also, because of the need to guarantee compatibility with a Microsoft Windows
NT/2000 environment, an option is provided (configurable in setup) to append a
NULL character to the end of all string data, making it look like a Microsoft device
(select Select | System | Setup | Connectivity | Internet | DHCP | Advanced |
Microsoft Server check box). This option is not required, and should only be used
if you can not do what you need to in your particular network environment. The
software is normally able to work with Microsoft servers, although there may be
some cases that require this option to be set.
Because of the established administration strategy, the default behavior is for the
terminal to request NO options in the 128 through 254 "site-specific" option space.
Because this is known to cause problems in some environments, Setup can be
used to modify the set of options requested, after your administration strategy is in
place. Any option used in this space is also available through option 18 or through
option 43, if you choose to use those methods instead.

T1500/T1510-Specific Option Definitions

The T1500/T1510-specific options are defined in the following subparagraphs.

Option 43 Vendor-Specific ID

This integer field is a key that is used to indicate that the option 43 data is indeed
intended for use with a T1500/T1510 terminal. If vendor-specific Option 1 is not
provided, or if its length is not exactly 4, or if its value does not match the tag value
listed in Table 2-2, the option 43 data is ignored in its entirety.

NETSVC

An additional set of software is provided to be stored on a server for use with the
terminal. This image can be stored in either Windows environments or UNIX
environments, and exported as a share or via NFS, as appropriate. This option
provides the network path to this directory. The syntax for NFS is machine:
/path, where machine is the IP address or DNS-resolvable machine name for
the server, and path is the full pathname to the directory. The syntax for SMB
