This is additional patch to support NEC PC-9800 subarchitecture
against 2.5.61-ac1. (6/21)
FAT fs and partition table support for PC98.
FAT fs created by PC9800 MS-DOS has curious media descripter. (BUG?)

This is additional patch to support NEC PC-9800 subarchitecture
against 2.5.61-ac1. (10/21)
C-bus(PC98's legacy bus like ISA) network cards support.
PCI netwwork card works fine without patch.

To: Linux Kernel Mailing List; +Cc: Alan Cox
This is additional patch to support NEC PC-9800 subarchitecture
against 2.5.61-ac1. (17/21)
Serial port support for PC98.
- Patch for onboard modem.
- New driver for 1st COM port.
PC98 has 2 COM ports. 1st port uses 8251 upper compatible chip
and 2nd port uses 16550A compatible chip.
