The NIC is detected by the OS, but I cannot get it to recognize the card.

what kind is it?

I told you ! It's a NIC !

Sorry I took it to mean Network Interface Card

never heard of an NIC

He was asking you what brand/model and even if it's ethernet!

then while you are at it you can mention for sure that it is Redhat 8.0 and that you know the OS recognized it because you saw that info where? Maybe even what you mean by not recognizing the card, as in you try to do what that isn't working. And even which HOWTOs or books or info at Redhat's site you have already checked.

I am sorry
The NIC is a SMC 1255tx, which is compatible with the SMC ez series. A cat /proc/pci lists an Accton tech en-126 ethernet adapter with an I/O at 0x2000 [0x200ff] and non-prefetchable memory at 0xf4100000 [0xf41003ff]
I do not know the IRQ allocated by the Bios, but when I try the command: 'ether=13,0x2000,eth0' nothing happens. (I tried IRQ 13 because Linux said that it was a free Irq line)

So, the NIC is detected by the computer. Now, how do I tell Linux where it is, as well as the module to control it

thanks

you can open a terminal as root and type:
netconfig (opens a simple console and follow the instructions for either dhcp or static IP)

after that type
mii-tool (if your nic is configured, you should see an "OK" at the end of the display)

if you don't get an OK, type
ifconfig -a > ifconfig.txt (copy and paste the file you just created in your root directory back here)

IMHO with an Intel NIC you'd have avoid a lot of issues.

Their latest PILA8460C3 (chip 82559 I guess) are perfectly supported and do not need any additional scratchy manipulation.

yeah. Usually when things are supported by the OS they install alot easier

This shouldn't be as hard as it appears.

First, be sure we are discussing the correct card. Can you check your documentation and confirm:
a. This is the SMC 1255tx
b. This is not SMC 1255tx-px
c. This is not SMC 1255tx-sc

2. according to smc, this takes the standard tulip driver which comes with every distro today.

open a terminal and type
lsmod (you should see tulip)

if you don't

insmod tulip
or
modprobe tulip (if you get no error message, then your module is probably loaded.)

3. configure your nic by opening a simple console by typing
netconfig (follow instructions provided for static or dhcp configuration)

4. check your work by typing
ifconfig -a (make sure the eth0 entry as the word "UP" )

Try turning OFF the "Win32/Plug and Play" option in your BIOS and try the detection again. this worked for me and several otheres who have had this same problem.

I got it to work
all I needed to know was how to associate the tulip driver with the NIC card
thanks everyone for the help
