cards because there is currently no automated way of keeping the files on the
Flash card and the server synchronized.
For ordering and other information about obtaining Flash memory cards,
software, and documentation necessary to use this functional enhancement,
please contact your IBM representative or an IBM Business Partner and refer
to PRPQ P97000, 5799-GEB, Feature Number 4002. In addition, unless you
have one of the few early Ethernet IBM Network Stations which shipped with
a PCMCIA slot, you must purchase a PCMCIA Adapter option for your Series
1000. This chargeable PCMCIA Adapter (part number 07L8336) option can
be ordered by contacting your IBM representative or an IBM Business
Partner. Additional details on the PCMCIA Adapter option and using Flash
memory cards can be found online at the Web site:

A peer boot scenario in which Flash memory cards are used is shown in
Figure 7 on page 30. As shown, the central location consists of an AS/400,
S/390 and RISC/6000 systems, which are connected to a remote location
across a wide area network link. In this case, one of the remote IBM Network
Stations has a Flash memory card inserted into it which contains the
operating system kernel and the executable modules required for the native
5250, 3270 and VTxxx emulators. This Flash card is used to boot the Network
Station it is inserted in and any other Network Stations at the remote site on
that subnet. However, after user authentication is done by the central site
AS/400, user preferences, fonts and other more volatile data is downloaded
from the central site. Please refer to Chapter 3, “Using Flash Cards with the
Network Station” on page 63 for a comprehensive discussion of Flash card
scenarios.
If a
boot server capable system exists in your remote sites, give careful
consideration to using it rather than a Flash card solution due to the
non-automated maintenance nature of Flash cards.
