SCSIMode is a utility that allows changing page data from any page on a
SCSI-2 drive.  SCSIMode is host adapter independant because the SCSI command
is sent through an ASPI driver.

The ASPI driver must be installed according to the manufacturer's instructions
before using SCSIMode.  SCSIMode will return an error if no ASPI driver is
found.

USAGE: SCSIMODE adapter targetID targetLUN page offset mask AND|OR|NOP|DEF [V]
	(All parameters should be specified in hex)
	adapter:	Host adapter number (NOT SCSI ID!) (0-7)
	targetID:	SCSI ID of the target device (0-7)
	targetLUN:	Logical Unit Number of the target device (0-7)
	page:		Mode page to read and/or write
	offset:		Byte offset within the page of the parm to change
	mask:		The byte mask that will be applied to the parm
	AND|OR|NOP|DEF:	The operation to be performed on the parm
			AND:	AND the current value with the mask
			OR:	OR the curreent value with the mask
			NOP:	Do nothing.  Do not change any page values
			DEF:	Change all parms back to default values
	[v]:		Verbose mode.  Display info from each ASPI call.

To simplify the interface, four batch files are included.  Each takes the
target drive SCSI ID as a parameter and reads or changes the page 8 write
caching bit status.

WC_ON.BAT will turn on the page 8 write caching bit on some SCSI-2 drives
WC_OFF.BAT will turn off the page 8 write caching bit on some SCSI-2 drives
WC_READ.BAT will display the current page 8 mode sense data.  The value to
  inspect is the third entry under 'Mode Sense Data'.  A value of 10 indicates
  that the write caching bit is off,  14 indicates that the bit is on.
WC_RESET.bat will set all page 8 parms back to the factory defaults.

WARNING: This utility can be used to change ANY of the parameters marked
as saveable by a SCSI-2 device.  Changing random drive parameters may render
your drive useless.  Make SURE you understand any parameter you are
considering changing.  Record the current value for a parameter prior to
changing so that you may later return to a known state.
