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
 --------------------------
 DOS\CMD640X.VL  - BIOS w/ 1 IDE channel support (2-drives)
 DOS\CMD640X2.VL - BIOS w/ 2 IDE channel support (4-drives)

NOTE:  INSTALL will automatically figure out which kind of hardware
       you are running on, and select the proper driver.  
       
       If you desire to copy the CMD DOS driver directly from this 
       release to the hard drive instead of using INSTALL, 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
