[amalik]

I installed second nic in pci slot on the box running sco 5.0.5 and the after the reboot the console went blank. Seems a hardware conflict. How can I resolve this?

No obvious conflicts in hardware settings

Take the nic out again?

Have a different nic you can try or another available slot to try the nic in? I'm guessing you are right about hardware conflict, probably in mapped I/O or memory address space. Try turning off all BIOS caching on the server?

Which kind of NIC ?

Print the result of the

hw -r pci

command.
Insert the new NIC in an empty slot and remove the old one.
If the system reboots without the blank screen problem, you have definitively a H/W conflict on the PCI bus.
Print the result of the

hw -r pci

command.
Compare the two listings with special care on this lines:

BaseAddr

and

InterrupLine

.
