What's going on

[Ragnar Wiencke]

Hi there.   I just installed RH7.2 on a box that I previously had run on RH6.2. I just added 1 HD and did a server install creating new partitions on both HD's. Now the nic isn't detected and when I try to mount the CDROM I get the messages     mount: /dev/cdrom is not a valid block device What did I do wrong?   Tia, Ragnar W.
