i am using redhat 6.2 ver. and i want to get on the internet. i just bought a linksys.Model No. LNE100TX ethernet adapter. version 4.1 I am using a cable modem to connect to the internet through a company called (Videon) aka. powersurfr.com they use DHCP. But i don't think linux is seeing the adapter. I tried a tulip.o that was already loaded with the 6.2 cd. But i think i might need to load the vendor driver on the disk that came with the adapter. And i don't think vender driver is RPM user friendly. so how do i install the vendor driver though the floppy disk drive (3.5) jack

Well, you need to take a look at the information on the floppy and see what's there. Chances are whatever is on there the disk is documented in a README file on the disk as well. Basically you need to "mount" the floppy disk in order to access it. You want to execute the following as root:
mount -t vfat /dev/fd0 /mnt/floppy

Now this is assuming that they formatted the floppy as fat16, or the typical window format. If they formatted it for Linux execute:

mount -t ext2 /dev/fd0 /mnt/floppy

Both of those lines mount the floppy drive in the /mnt/floppy directory which you can then "cd" into and see what's there.
