AS/400 IBM Network Station: Techniques for Deployment in a WAN
For additional information about planning for, and implementing the IBM 2212
and the Thin Server Feature, refer to the manuals:
IBM 2212 Access Utility
Introduction and Planning Guide
, GA27-4215, and IBM 2212 Access Utility
Installation and Initial Configuration Guide
, GA27-4216. These manuals are
available online at the Web site: www.networking.ibm.com/did/2212bks.html
In addition, as mentioned previously, a future IBM redbook discussing the IBM
2212 Access Utility is planned for availability in 1999.
1.4.3 Flash Memory Card Boot
Another option available to you for small remote sites is to use local Flash
Memory Cards. The Flash Memory Card enhancement for IBM Network
Station Manager, Release 3, allows you to store the IBM Network Station
operating system and applications on certain third-party Series D Type II
PCMCIA memory cards and boot a remote IBM Network Station locally.
Linear Series C cards are also supported but these are limited in size to
10MB, whereas the Series D cards are available in a range of sizes up to 32
MB and in the near future will most likely support 40MB.
IBM has tested PCMCIA memory cards from both Centennial Technologies
and Simple Technology. After you obtain a new Flash card, it must first be
formatted and then files can be copied to it. The IBM Network Station's
NVRAM is then changed to indicate that the Network Station is to boot itself
from this local media. Details on this procedure are discussed in Section
3.3.10.2, “Modifying the NVRAM Configuration for Local Boot” on page 91.
In addition to the (mandatory) operating system, the code to be booted can
include any of the optional software modules for the IBM Network Station
such as emulators, browser, ICA client, window manager, JVM, and fonts. In
addition, the Flash card may contain user Java applications. One of the first
steps is to determine which files you want to place on the card and what size
Flash memory card you will need. Also, consider that separate files are
sometimes required for the Series 1000 models. Therefore, if you intend to
peer boot a mixture of Series 1000 and other models, you will need both sets
of files and the card size approximately doubles. We highly recommend you
place larger, more stable files on the card and let other smaller files, such as
configuration preference files, download from the server across the network.
The local Flash card and
peer boot solution is normally less expensive than
the other solutions. However, a maximum of 10 IBM Network Stations booting
from a peer IBM Network Station have been tested by IBM. In addition, after
selecting the files to put on the card, you must
manually maintain the Flash
