DOS DRIVER USAGE
----------------
If your system's BIOS supports only 1 IDE channel (Primary), use
CMD640X.xxx (where xxx can either be PCI or VL).  If your system's BIOS 
supports 2 IDE channels (Primary and Secondary), use CMD640X2.xxx. 
                                 
 Drivers for PCI-Bus systems
 --------------------------
 DOS\PCI\CMD640X.PCI  - BIOS w/ 1 IDE channel support (2-drives)
 DOS\PCI\CMD640X2.PCI - BIOS w/ 2 IDE channel support (4-drives)
 
 Drivers for VL-Bus systems

The install program will copy the appropriate driver to your hard drive.
If you copy the CMD DOS driver directly from this release to the hard drive,
you need to rename the target file extension to be .SYS.

For PCI system, copy the CMD DOS driver from the sub-directory \dos\pci.
    e.g. copy a:\dos\pci\cmd640x.pci c:\cmd640x.sys

For VL system, copy the CMD DOS driver from the sub-directory \dos.
    e.g. copy a:\dos\cmd640x2.vl c:\cmd640x2.sys
