I installed Mandrake 10.0 Official using the network bootdisk, and it worked fine with my 3Com 3CCFE574BT PC Card, but after Mandrake was installed, it could not find the card. And I can't setup networks, or go on the net. Please help.

Open a console and as ROOT (see FAQ's if you cant do this)

type lspci -v -v
this should list all your PCI interfaces.... try and find the one for your PCMCIA and hopefully also the 3COM card ...

Also you could try to
cat /proc/pcmcia
to see if its active

/etc/init.d/pcmcia status
should tell you if its running and if not
/etc/init.d/pcmcia start
should start the service.

(I think thats what you mean PC card=PCMCIA card ? the names keep being changed )

If it hangs .... darn it itll be more work....

let us know

Yeah,pc card is PCMCIA
I'll try this

OK, thats just as start....
post back when you find out .... and we'll see what we can do

lspci -v -v didn't work its said command not found.

And /etc/init.d/pcmcia status showed it wasn't running so I started it then it said: cardmgr[2685]: no sockets found!

Ok so I reinstalled mdk in hope that it would work (it didn't)
But I looked at the kernal messages as I did the network install.
And it showed me this:
the card according to it is: Megahertz 574B
and I believe it is in IRQ 11

I figured it out!
Ya go me!
It was the help gotten here, and a little bit of help from other source that I adapted from Wireless.
And then I just made some judgement calls.
Not to bad for a n00b?

Can you post your fix as i'm having the same kind of problems
Cheers
