Windows 98 cannot remember drivers

Hello all.

I have a really old laptop (panasonic toughbook CF25 Mk3) 166mghtz
I have installed windows 98 se on it.
I have all the drivers and have installed them all.

the problem is when I reboot windows forgets the drivers for the pcmcia slots and the pci usb bridge, if I go into the device manager and reinstall the drivers it finds them and installs them and then all of the yello exclamation points disapear. but if I insert my pcmcia to usb 2.0 card the drivers for that are installed and then it tells me to reboot and then the drivers for the slots are forgotten again.

Can anyone help me fix this problem.

thank you for taking the time to read this
