Network interfaces problem

Hi,

I have problems with my SCO unix network interfaces.
Intel integrated adapter was failing, so I installed new one - 3COM adapter into free PCI slot.
Installed driver using SCO Software manager - successfully
Added new Network adapter using SCO Network configuration manager - successfully
after that I checked using ifconfig -a
there was some loopback interfaces and - net0 -intel interface, and net1 -3com interface.
So I thought that everything is OK and removed intel adapter using Network configuration manager, after that things went wrong:
ifconfig -a displays only loopback interfaces.
3com driver is installed, 3com network adapter is added(Network configuration manager), but ifconfig -a don't display it!!!

So I thought that it's hardware problem - booted knoppix from cd - my 3com adapter is autodetected, up and running!

After that I tried all 'dumb' ways - rebooted, reinstalled(driver), changed apapter pci slot...- result is the same -driver - OK, adapter(Network configuration manager) - OK, "ifconfig -a" - no entries. By the way devices net0 and net1 are present(I asume net1 is my 3com adapter).

I'm newbe in unix so maybe I missing some 'obvious' step ?
How to force my 3com adapter(net1 ?) to apear in ifconfig list, and force it function corectlly ?

thank you
Vilius

NAME
ncad_addr - name of the Solaris Network Cache and Accelerator (NCA) socket utility library SYNOPSIS
/usr/lib/ncad_addr.so DESCRIPTION
ncad_addr.so is the Solaris Network Cache and Accelerator (NCA) socket utility library. Use this library with a web server to avoid support for the PF_NCA family type socket. The web server can take advantage of NCA functionality. Interpose the ncad_addr interfaces before the interfaces in libsocket by setting the environment variable LD_PRELOAD to ncad_addr.so so that it is preloaded before libsocket.so.1. The ncad_addr.so interfaces will be interposed only if NCA is enabled. See ncakmod(1). EXAMPLES
Example 1: Interposing ncad_addr Using Bourne shell syntax as an example, set LD_PRELOAD as shown below to interpose the ncad_addr socket utility libary: LD_PRELOAD=/usr/lib/ncad_addr.so /usr/bin/httpd FILES
/usr/lib/ncad_addr.so ncad_addr socket utility library shared object ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWncar (32-bit) | +-----------------------------+-----------------------------+ | |SUNWncarx (64-bit) | +-----------------------------+-----------------------------+ |Interface Stability |Unstable | +-----------------------------+-----------------------------+ SEE ALSO
nca(1), ncab2clf(1), ncakmod(1), socket(3SOCKET), nca.if(4), ncakmod.conf(4), attributes(5) NOTES
Only applications that use the NCA feature, for example, web servers, should interpose this library. SunOS 5.10 18 Feb 2003 ncad_addr(4)
