Arco Product(s):        AC-32VL and AC-32VL+

Environment:       VESA Local Bus

Description: Arco has updated the device driver for the AC-32VL 
and AC-32VL+. The enhanced driver offers the user better 
control of the operating environment by  inputting hard drive 
and computer processor information specific to their computer. 
AC32VLB.EXE is a Beta version, not the final release.

Solution  : Copy the driver AC32VLB.EXE to the boot directory.

	    Make the following addition to the CONFIG.SYS file:
	    
	    DEVICE=C:\AC32VLB.EXE_/x_/y_/z ("_" denotes a space)

	    Where x = Processor speed as follows:

	    For an: 80486 DX-16             Enter:  DX-16
     		    80486 DX-20                     DX-20
		        80486 DX-25                     DX-25
		        80486 DX-33                     DX-33
		        80486 DX-40                     DX-40
		        80486 DX-50                     DX-50
		        80486 DX2-50                    DX2-50
		        80486 DX2-66                    DX2-60

OPTIONAL  The AC-32VLB.EXE driver will automatically query the 
hard drive to determine the ATA protocol mode. If you wish to 
force the mode setting, or if the mode is not being set 
correctly, the /y and /z information should be set.

       Where y = hard drive C: ATA protocol mode and
       Where z = hard drive D: ATA protocol mode as follows:

	      For:    mode 0          Enter:  0
		          mode 1                  1
		          mode 2                  2
		          mode 3                  3
