3. Base conﬁguration

• Copy the keyboard layout map you have just created to your ﬂi4l directory under

opt/etc/ locale .map. If you now set KEYBOARD_LOCALE=’ locale ’, your freshly

created keyboard layout will be used when building the ﬂi4l images the next time.

• Don’t forget to set OPT_MAKEKBL to ‘no’ again.

3.7. Ethernet network adapter drivers

NET_DRV_N Number of needed network adapter drivers.

If you use the router with ISDN, you typically have one network adapter only, hence the

default value is 1. However, if you use DSL, you will have two network adapters in the

majority of cases.

You have to separate two cases:

1. Both adapters are of the same type. Then you will have to specify only one driver

communicating with both adapters, hence NET_DRV_N=’1’.

2. The types of the adapters used diﬀer. Then you have to set the variable to ‘2’ and

to conﬁgure the drivers separately for both adapters.

NET_DRV_x NET_DRV_x_OPTION This variable contains the name of the driver to be

used for the network adapter. The default for NET_DRV_1 is to load the driver for a NE2000

compatible network adapter. More available drivers for a large amount of families of

network adapters are included in the tables 3.3 and 3.4.

The 3COM EtherLinkIII network adapter (3c509) has to be conﬁgured by the DOS tool

3c509cfg.exe, available under:

ftp://ftp.ihg.uni-duisburg.de/Hardware/3com/3C5x9n/3C5X9CFG.EXE

It should be used for setting the IRQ and I/O port and, if necessary, the type of connec-

tion (BNC/TP). The entry NET_DRV_x_OPTION=” can normally be left empty.

Some ISA adapters require the driver to have additional information in order to ﬁnd the

adapter, e.g. the I/O address. This is the case e.g. for NE2000 compatible ISA adapters

and the EtherExpress16.

In such a case, you can set

NET_DRV_x_OPTION='io=0x340'

(or the corresponding numerical value).

If no options are required, you can leave this variable empty.

If you need to specify more than one option, you have to separate them by blanks, e.g.

NET_DRV_x_OPTION='irq=9 io=0x340'

If you use two identical network adapters, e.g. NE2000 ISA adapters, you have to separate

the diﬀerent I/O ports by commas:

NET_DRV_x_OPTION='io=0x240,0x300'
