Ethernet card not working

A google search under "Microsoft Notebook Adapter MN-120" has revealed
an interesting dialog on the subject here:

However, before editing the source code for the tulip module, try using
it unedited first:
su to a root prompt then run this command:

modprobe tulip

The tulip driver sourcecode can be obtained from Scyld, here:

Your problem is that you are using a Microsoft product and that company
is ill disposed to providing anything that will help linux users.

The price of network adapters is very low. My suggestion is that you get
an industry standard one.

In order to save you some headaches, just go online or to a local shop and
buy a Linux compatible NIC. Check the the HCL on redhat.com and then search
for a specific NIC or for a specific NIC chipset that works with RH. I buy
my NICs from a shop here in town for $9. They work fine with Linux.

The reason why you can't detect a modem is because you're using a WinModem.
By definition it wont work with Linux. You need a PCI Hardware modem or a
externel Modem. Again use the HCL on redhat.com & pricewatch.com to find a
modem.

Remember you're coming from the Windows world where almost all hardware sold
in stores works with Windows. Linux is more tight with issues of hardware
compatibility. You should use the HCL, it makes life much easier.

what is HCL? and remeber i'm using a notebook

Whoops sorry I misread that you are using a notebook, I thought it was a
desktop.

Anyway, the HCL stands for Hardware Compatibility List. Self explanatory.

I can't help you with PCMCIA stuff, I don't use notebooks at all.
