1) – Here, you can choose the I/O „BASE“ address. This address must lie between the

minimum and maximum address and conform to the „base alignment“.

If your system uses more than one ISA adapter, you will have to ensure that there

are no overlaps between address ranges. The address range starts at „BASE“ and

ends at „BASE + Number of IO addresses required“.

2) – Here you can pick an IRQ from the list shown. The IRQs 2(9), 3, 4, 5, and 7 should

be avoided as these IRQs may clash with your serial and parallel interfaces or the

interrupt cascading.

ISA adapters are not able to share IRQs, thus the IRQ you choose here may not be

used elsewhere.

• Put the chosen conﬁguration (IRQ/IO) into conﬁg /isdn.txt

• In order to let the necessary ﬁles be copied to the boot medium, you must set OPT_PNP

to ’yes’ in conﬁg /base.txt. The variable MOUNT_BOOT can be chosen freely, however.

• Create new boot medium

The automatically generated ﬁle contains Unix line endings (LF without CR).

Thus, if you use Notepad under Windows, all content is shown in a single line. In

contrast, the DOS editor “edit” is able to cope with the Unix line endings. When

saved, however, they are changed to DOS line endings (CR+LF).

Workaround:

• start DOS box

• change to the directory conﬁg /etc

• type: edit isapnp.conf

• edit ﬁle and save your changes

After that you can also use Notepad to edit the ﬁle.

Under Windows you may also use the Wordpad editor.

The CRs generated by the “edit” tool are ﬁltered when ﬂi4l boots and thus do not disturb.

Please try ﬁrst to get along without using OPT_PNP. If the adapter is not recognized you may

follow the procedure described above.

If you update to a more recent ﬂi4l version, you may reuse the previously created isapnp.conf.

Default setting: OPT_PNP=’no’

4.2. Advanced Networking

The package ’advanced networking’ provides bonding and bridging capabilities for the ﬂi4l-

router. EBTables (http://ebtables.sourceforge.net/) support can be enabled as well. This

allows to build a transparent packet ﬁlter. To all options of the advanced_networking package

generally applies:

This package is only for users with profund knowledge about networks and

routing.
