98SE/ME NVIDIA nForce4 Ultra Chipset Driver

I am running a triple boot system, 98SE / ME / XP Pro. I have just upgraded
with a new motherboard with an NVIDIA nForce4 Ultra Chipset. Does anyone know
of a 98SE / ME driver for this chipset or maybe a work around in order to get
these two FAT systems up and running? I am not looking to use any of the
special features of this chipset like RAID or SATA, I just want these systems
to operate the way they were originally designed with the new motherboard? I
am able to boot the systems but the Desktop looks like a Safe Mode display
and there are no Hard Drives or CD drives listed in Device Manager or My
Computer, only a Floppy Drive. I can access the two FAT partitions with no
problem as they are listed in My Computer as C & D drives. The systems run in
MSDOS Compatibility Mode and I am unable to do a registry repair deleting the
NOIDE value as there is none listed. Any help in solving the problem would be
most appreciated.
