Directions for using the EXM29 configuration software:
------------------------------------------------------

Overview:
	This program is intended to provide an easy way to set the
	'Option Byte 3' and 'Option Byte 4' registers of the
	RadiSys EXM29 under DOS (see manual for register details).

	By including a call to this program from within the autoexec.bat
	file, the registers can be set on system boot, without programming.

Files:
	The program consists of the DOS executable file, 'exm29cfg.exe'.

Usage:
	Invocation of the program is as follows:

		exm29cfg [/q] [/slot:<val>] [/ob3:<val>] [/ob4:<val>]

	Options may be preceded by either a forward slash, '/', or
	a hyphen, '-'. Options may be added in any order. Values are
	always separated from the option by the colon, ':'.

	Integer or hexadecimal values must not be preceded or trailed
	by additional characters or padding. For example, the hex value
	3E8 must be entered as '3E8', not '0x03E8' or '3E8h'. Zero must
	be entered as '0', not '00'. Options and values are
	case-insensitive.

 	One special option is pre-defined. This is the '?' option.
	On encountering this, the program exits and displays a summary
	of options without fully invoking the program.
	
	Options are not required. All have default values. A quick
	review of the default values can be obtained by invoking the
	program with the summary option, '/?'.

	Any option not explicitly set will be treated as though it
	were set with the default value.

Options:
	/q -	This option directs the program not to display any
		messages while running or upon completion, except
		in the case of error. This is useful when the program
		is invoked from the autoexec.bat.

	/slot - This is the slot in which the EXM29 to be configured
		resides. This should be an integer value.

	/ob3 -	This guides the value for the Option Byte 3 register.
		The value associated with this option should be the I/O
		address, in hexadecimal, at which EXM29 port 1 will be
		based. The program will take care of adjusting this
		address such that the appropriate value is loaded into
		the Option Byte 3 register.

	/ob4 -	This guides the value for the Option Byte 4 register.
		The value associated with this option should be the I/O
		address, in hexadecimal, at which EXM29 port 2 will be
		based. The program will take care of adjusting this
		address such that the appropriate value is loaded into
		the Option Byte 4 register.

Errors:
	All error messages and usage summaries will be sent to the
	standard output.

Examples:
	Assuming an EXM29 in slot 3, to configure the port 1 base
	address at 3E8h, and the port 2 base address at 2E8h, the
	program would be invoked as follows:

		exm29cfg /slot:3 /ob3:3e8 /ob4:2e8
