#E.1.2.4 Examples:
#To install HIMEM.SYS, using the default values, add the following line to
#the CONFIG.SYS file:
# DEVICE=HIMEM.SYS
#Since no location is specified, DOS searches for HIMEM.SYS in the root
#directory of your startup drive.
#Suppose you want a program to use at least 40KB of memory before it has
#access to the HMA. To specify this and that HIMEM.SYS is located in the
#DOS directory of drive C, add the following line to the CONFIG.SYS file
# DEVICE=C:\DOS\HIMEM.SYS /HMAMIN=40
#To install HIMEM.SYS and specify the A20 handler for the Model L40 SX, add
#either of the following lines to the CONFIG.SYS file:
# DEVICE=HIMEM.SYS /MACHINE:PS2
#or
# DEVICE=HIMEM.SYS /MACHINE:2
