+    DEVLOAD 3.20 USER GUIDE
+    -----------------------
+
+    DEVLOAD is an utility for loading device drivers from command line.
+It supports FAT16 & FAT32 block device drivers   (e.g. DI1000DD.SYS and
+ASPIDISK.SYS),  COM & EXE  -  style  DOS  device drivers and has a very
+compact binary file (less than 3Kb). 
+
+    Usage
+    -----
+    Usage:    DEVLOAD [switches] filename [params]
+    Emulates: DEVICE=filename [params] in CONFIG.SYS
+
+    Switches:
+      /? - display help message.
+      /H - try to load driver to UMB.
+           (equivalent of DEVICEHIGH=filename [params] in CONFIG.SYS)
+      /Q - quiet mode.
+      /V - verbose mode.
+      /A - auto-mode (force to stay loaded).
+
+    Examples:
+      1) USBASPI from command line
+         DEVLOAD /H USBASPI.SYS /V /W
+         DEVLOAD /H DI1000DD.SYS
+
+      2) ASPI driver for IDE (e.g. for CDRTOOLS)
+         DEVLOAD ASPI.SYS
+
+    System requirements
+    -------------------
+    * DOS 3.00 and higher
+    * Intel 8086 CPU, 640Kb of RAM
+    * MS-DOS 7.1/8.0, PC-DOS 7.1, LZ-DOS 7.1, 
+      FreeDOS 1.0, EDR-DOS WIP 17.6.2007+
+      for FAT32 block device drivers support
+    
+    WARNING: DEVLOAD cannot load FAT32 block device drivers under PTS-DOS 32!
