This file is the README.TXT for the BusTek SCSI board utilities

BOARDID		Reads all EISA slots and reports the EISA id (EISA config
		file name ) of all boards found in the system. Note: the
		system does not have to be configured for this program
		to run.

SHOW_CFG	Displays the EISA configuration of all CONFIGURED BusTek
		FAST-SCSI EISA cards. This is only valid for BusTek FAST-
		SCSI EISA cards.

SCSI_DMA	Checks all possible DMA bus transfer rates for Bt542 cards.
		The last passing DMA rate could then be set with SET_DMA.

		The -L6 -L8 -L10 switches limit the maximum tested rate to
		less than 6.7, 8.0, 10.0 Mhz respectively.

		SCSI_DMA reports its results in the following form -

91 DMA rate  8.0 Mhz with read pulse 150 ns  strobe 100 ns passed
88 DMA rate  8.0 Mhz with read pulse 100 ns  strobe 150 ns      *** FAILED ***
^             ^                      ^              ^       ^ test status
^             ^                      ^              ^ strobe pulse width
^             ^                      ^ read pulse width nanoseconds
^             ^DMA rate in megahertz's
^parm for SET_DMA

		SCSI_DMA does only a very crude test of the DMA. The BIOS
		test should be used to verify proper operation. The BIOS test
		does not change the DMA rate when run so the results will be
		valid. Aggresive rates( greater than 8 Mhz ) should be tested
		for extended periods ie. over night. The BusTek BIOS DMA test
		is run from DOS debug. Enter the following command  -
		- g=DC00:9   Assuming the default BIOS address of DC00.


SET_DMA	"parm"	Sets the bus transfer rate on BusTek ISA cards to "parm".
		Where "parm" is any valid DMA rate. SCSI_DMA reports all
		valid rates. SET_DMA will set the DMA rate for all BusTek ISA
		cards in a system. Once a DMA rate has been verified to work
		SET_DMA can be run from your autoexec.bat.


SCSITOOL        Scans the system bus for all BusTek SCSI controller
		addresses. SCSITOOL then reports the configuration and
		installed SCSI devices. On FAST-SCSI capable cards it will
		report the negotiated syncronous transfer rate. SCSITOOL
		output can be piped through the DOS command more or
		redirected to a file for later viewing. The BIOS is not
		required for SCSITOOL to run. SCSITOOL will be of most use to
		show the ID of SCSI devices on cards the BIOS is not enabled.


SWITCHES.TXT    Shows the most commonly set switch options for the Bt542b card
		using pc text graphics.

DMA_TEST	DMA test for memory above 1 megabyte.
		The /B switch allows optional start, stop addresses and offset
		ammount. Start and stop addresses are allowed on megabyte
		bounderies. Default is to test all memory from 1 to 16
		megabytes.
		Restrictions
	* 	Do not use a high memory manager.
	*	Do not use an ASPI manager - BTDOSM.
	        These restrictions are needed since all memory above one
	        megabyte is trashed.
