I have installed Oracle Enterprise Linux 5 in my PC. After the installation the Ethernet Card is not got detected.
But I could able to get the details using the command lspci -a:
01:00.0 Ethernet controller: Attansic Technology Corp. L1 Gigabit Ethernet Adapter (rev b0).
What do you mean by "I could not able to make work"? That you don't have a network connection? That the card wasn't configured? Or that Linux doesn't see it?
