It appears that you have defined two NICs. The ancient
PCNTND.OS2 driver is for an old 100 Mbs NIC. I suggest using the
network driver for the Intel 1000 Mbs NIC (the first one in the list
works well). BigIcons are also not necessary. If you don't want
those things, deselect them in the installer. Randomly REMing lines
in CONFIG.SYS is not the best approach.

Doug, i'm in "trouble" :)

i've put Intel pro 1000 but i'm not finding a single driver that works with
this configuration

altready tried, but they don't work

e1000.os2, ibmgc.os2, ibmge.os2, mmigb.os2....  :(
