Fixed bad things commented by Russell King. PC-9800 series machines are made by NEC. But sold only in japan. Formaly, they were best sellers in japan. We port linux for PC-9800 since 2.1.57. I'm testing 2.5.43 with this patchset on some boxes. - PC-9800 i586 UP with IDE drive - PC-9800 i686 SMP with SCSI drive - AT compatible with IDE drive (patch applied but not set CONFIG_PC9800). They works well. We are doing our best, patchset has no effect on original without configuring for PC-9800. Please apply this patchset. Best regards Osamu tomita sf.jp Linux/98 project - This is part 1/26 of patchset.
