!        --------------------------------------------------------
!        direct access routines to ATA device under Solaris/SPARC
!        --------------------------------------------------------
! 
! Information
! -----------
! 
! In Solaris, programmer can pass SCSI command to target device directly
! by using USCSI ioctl or using "scg" generic SCSI driver.  But, such
! method does not exist for ATA devices.
! 
! However, I can access Solaris kernel source because I am subscriber of
! Source Foundation Program of Solaris.  So, I can find method of
! accessing ATA device directly.  The method is to pack command in
! undocumented structure and issue ioctl that appears only in kernel
! source.  Yes, that is the same way in using USCSI interface.
! 
! But, I met difficulty in disclosing this technique.  I have signed NDA
! with Sun that inhibits me not to violate their intellectual property.
! 
! Fortunately, Sun allows licensees to publish "Interfaces" if:
! 
! (1) he/she treats Solaris code as confidential
! 
! (2) and he/she doesn't incorporate Sun's code into his/her code
! 
! (3) and disclose enough information to use "Interface" to everyone.
! 
! So, I publish that technique in assembly code or object code because:
! 
! (1) I believe Sun's intellectural property is not invaded because I
!     didn't reveal any struct member and ioctl to non-licensee.
! 
! (2) no piece of kernel source is included in this code.
! 
! (3) And finally, I publish enough information below in order to use
!     this code.
! 
! For last reason, please don't remove "Calling Interface" section from
! distribution.
! 
! 
! Calling Interface
! -----------------
! 
! Name of function/macro presents corresponding S.M.A.R.T. command.
! 
! Parameters are described below.
    ! 
! int fd
! 
!     File descriptor of ATA device.  Device would be
!     /dev/rdsk/cXtXdXsX.
! 
!     Device should be raw device serviced by "dada" driver.  ATAPI
!     CD-ROM/R/RW, DVD-ROM, and so on are not allowed because they are
!     serviced by "sd" driver.  On x86 Solaris, "cmdk" driver services
!     them, this routines doesn't work.
! 
! int s
!     Select sector for service.  For example, this indicates log sector
!     number for smart_read_log() function.  Probably you need to read
!     ATA specification for this parameter.
! 
! void *data
!     Data going to be read/written.  It don't have to be word aligned,
!     But data shall points valid user memory space.
! 
! This is very tiny routines, but if you feel this insufficient, please
! let me know.
