ATA-mkIII has three big problems.
1. It seems that CHS mode is broken.
I think that NAKAJI-san's trouble is due to it.
I also got the following error on my pc98.
ad1: 407MB <WDC AC1425F 25.26H35> at ata0-slave BIOSPIO

2. A geometry translation for pc98 is NOT enough.
Currently, it works only under 4.3GB disk.
3. Modules for pc98 are broken.
I attach a patch to fix it.
