	- added warnings about CMD-640B and RZ1000 bugs to manpage ("-u1")
	- cleaned up output from -c, added text interpretations
	- added -c functionality to -v
	- removed -a functionality from -v for scsi drives
	- added -n flag for ignoring the "write error" bit from a drive
	- moved binary from /usr/local/bin to /usr/local/sbin
	- added support for 3rd/4th IDE interfaces
hdparm-2.3:
	- added -c flag for controlling 32-bit chipset features with 1.2.9+
	- fixed error messages when -t used on SCSI drives
	- fixed date on man page to read 1995 rather than 1994 (late change)
hdparm-2.2:

hdparm-2.1:
	- fixed formatting of DMA info line
