I can't use my Fedora Core 4 because booting it freezes the system. I installed it from the installation-DVD (went all the way normally) and then when the system boots again all goes well until the fedora's booting screen comes up. It loads normally all other other devices and programs but on loading PCMCIA-devices the screen goes fuzzy and the system freezes.

Is there some options to add to the boot sequence that would disable PCMCIA or can I get rid of this problem by doing something else like modifying some file?
In grub there's no failsafe mode or else, only normal boot of Fedora and Win Xp.

Yes, When the Grub splash screen is displayed press any key.

Highlight the Linux (Fedora) boot choice and press the 'e' key
Highlight the line that starts with something like 'kernel /vlinuz' and press the 'e' key again
At the end of the line add a space followed by nopcmcia
When done press the 'Enter' key followed by the 'b' key

Depending on your pcmcia controller you might want to disable the pcmcia service and/or edit the /etc/sysconfig/pcmcia and /etc/pcmcia/config.opts files.

Thanks a lot!
I got it working after some adjustments on those pcmcia files.
