First of all download the pcmcia_orinoco.lrp package from the Bering packages area and rename it pcmcia.lrp. This package is derived from the standard Bering pcmcia.lrp package and includes the orinoco drivers.
You then need to download the wireless.lrp package. Starting with Bering 1.2 you do not need libm.lrp anymore.
Depending on your ISP connection and your network hardware, declare the appropriate packages. For example:
ppp, pppoe, and pcmcia if you connect through an ADSL/PPPoE connection and have a wireless NIC connected through a PCMCIA adapter.
pcmcia if you connect through a fixed IP cable-modem ISP and have a wireless NIC connected through a PCMCIA adapter.
pump, pcmcia if you connect through a dynamic IP cable-modem ISP and have a wireless NIC connected through a PCMCIA adapter.
none of the above if you connect through a fixed IP cable-modem ISP and have a PCI native wireless card.
In the first case your syslinux.cfg file will
look like (adapt to your own case):
display syslinux.dpy timeout 0 default linux initrd=initrd.lrp init=/linuxrc rw root=/dev/ram0 boot=/dev/fd0u1680:msdos PKGPATH=/dev/fd0u1680 LRP=root,etc,local,modules,iptables,ppp,pppoe,pcmcia,wireless,keyboard,shorwall,ulogd,dnscache,weblet
The last two lines ("default linux ... dnscache,weblet")
must be typed as a single one in syslinux.cfg
