Large SATA Drives with 4.25

I am confused about setting up 250Gb WD SATA drives using qnx 4.25.
Should I use Fsys.eide or Fsys.atapi

When I try to setup disks i get problems > 137Gb. (maybe caused by ATA 28 bit sector limit)

If anybody has set up large SATA drive i would appreciate comments / help.

Fsys.atapi and you might need to use lba=48 option
