Q:As a developer, I sometimes need a real hard-copy listing. You provide very little information about setting up printers. Why?

A:We did not have time to experiment with printers while writing this redbook. This can become a complex topic quickly when network printers are considered. We hope to provide more detail if a follow-on redbook is written. Larger EFS systems often have channel-attached S/390 printers and no special documentation has been required to cover these.

Q:How long does the ThinkPad battery last?

A:With our fully loaded system (512 MB, two disk drives, heavy computational load) the battery usually lasted about 50 minutes.

Q:Is SNA available over Ethernet?

A:Not yet, at the time of writing. When it is available, the selection of DIX versus IEEE802.3 frames will be done by selecting an appropriate control unit type in the FLEX-ES definitions. Control unit type xcasna will select IEEE802.3, and xca will select DIX.

Q:Can I use a locally administered MAC address for Ethernet?

A:We have never done this, although it appears that some Ethernet drivers appear to support this option.

Q:How many Ethernet adapters do I need if I want to use SNA and TCP/IP?

A:We do not know yet.
