pcmcia EtherJet card problems in RedHat 7.2

Hi there !

I am trying to get my old Thinkpad 600 running on Linux RedHat 7.2, to
connect to the Internet via an IBM pcmcia EtherJet card. The card does
work on MSWIN 98 on the same system, so the hardware seems OK. My system
RedHat 7.2 includes pcmcia functions, and my file /etc/pcmcia/config does
include a mention of said card :

card "IBM 10/100 EtherJet CardBus"
manfid 0x00a4, 0x0113
bind "tulip_cb"

device "tulip_cb"
class "network" module "cb_enabler", "tulip-cb"

However, nothing works. Thereafter, here are relevant lines appearing
in my /var/log/messages :

.................

ping 192.168.1.1 gives "network unreachable. /sbin/ifconfig shows nothing
more that the loopback

Thanks in advance for any help in getting that EtherJet card to work on my
system
