r u using grub or lilo?
Here's the grub solution:
1. when u c the grub screen. type e - assuming u didn't set grub password
2. select the second line "kernel ....." and type e again
3. append a space then S to the end of that line " S" overall the line should look something like this "kernel /boot/<kernel version> ro root=LABEL=/ S" or something like this
" kernel/ boot/<kernel version> ro root=/dev/hda1 S"
4. press esc then b
You should now boot into single user maintanence mode. with a hash prompt #
Type "chkconfig --del pcmcia" and press enter
reboot your linux by typing "reboot"
IF you are using lilo. At the boot prompt type "linux single" to get into single user mode then do the chkconfig as above and reboot
That should solve it.
Cheers
