Drivers needed, urgently ! where can I find them?

Hi ! I'm looking for drivers for my modem and the multimedia buttons(like eject CD, volume, standby buttons, etc,) .
They aren't working since I upgraded from Win
98SE to Win 2K Pro . I've visited all drivers sites looking for them, but I haven't found any yet .
My modem is a RIPTIDE Conexant HCF Rockwell
PCI modem/fax/sound combocard .
My keyboard is a NETROPA/Hewlett-Packard MULTIMEDIA keyboard , model : SK-2506 .

Any help you can provide in finding those drivers, will be appreciated .
