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
   ad1: 833616 sectors [6129C/8H/17S] 1 sectors/interrupt 1 depth queue

   # mount -t msdos /dev/ad1s1 /mnt
   msdosfs: /dev/ad1s1: Invalid argument

   # dd if=/dev/ad1s1 of=/dev/null
   dd: /dev/ad1s1: Input/output error
   7+0 records in
   7+0 records out
   3584 bytes transferred in 0.027885 secs (128528 bytes/sec)
   kernel: ad1: FAILURE - READ status=59<READY,DSC,DRQ,ERROR> error=10<NID_NOT_FOUND> LBA=143


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.
