System information

Using Flash Cards with the Network Station

3.1.1 Flash Card Sizing

Table 16 provides an estimate of the card size required for each IBM Network

Station native application. The Series 1000 IBM Network Stations have a

different boot kernel. There are also separate executable modules required

for supporting the Series 1000. If you intend to peer boot a mixture of Series

1000 and the Series 100 and 300, you need both sets of files and the

required card size approximately doubles.

Table 16. Kernel and Application Program Sizes

The sizes assume that the compressed files (.Z or .z suffix) are used for the

kernel and fonts. All of the sizings presume that the login display (ACTLogin)

is being used and that all fonts and locale-specific data (keyboards, message

catalogs, and so on) are loaded from the server. If locale information is

placed on the Flash card, it can require up to 20 MB depending on the

application and the locale (this number is even higher for double-byte

locales).

You should allow several extra megabytes for future expansion of these files

because of the Network Station software enhancements. You should also

increase the Flash card size by the size of at least the largest file being put on

the card, if there is any plan to update the current card in place.

The numbers are additive. Therefore, the card size for the 5250 emulator is

the combination of the size of the (mandatory) Base OS kernel plus the size

of the 5250 emulator. Sizes are included for each of the example scenarios in

the PRPQ documentation.

ACTLogin or authentication login refers to the process in which a user ID

and password is used authenticate a particular user.
