ACER 5220 PC-NFS device driver is distributed on one 360K bytes
    diskette.	There are two pieces of program in the subdirectory
    \NFS5220, as following:

      a. NFS5220.SYS  - Acer 5220 device driver for PC-NFS,

	 Command syntax:

	  DEVICE=\NFS\NFS5220.SYS [/i#] [/p###]

	 where:

	  1. /i# is the hardware interrupt value used.

	  2. /p### is the base I/O port address in hexa.

	Argument 1,2 should be used only when the factory settings
	have been changed. If both of argument are omitted, the
	default values are IRQ2 and Port Address 260h individually.
	Its function is similar to give value like  /i2 /p260.

	Sample CONFIG.SYS file: (for Acer 5220 Ethernet controller)

	  ┌──────────────────────────────────────────┐
	  │  DEVICE=\ANSI.SYS			     │
	  │  DEVICE=\NFS\PCNFS.SYS		     │
	  │  DEVICE=\NFS\SOCKDRV.SYS		     │
	  │  DEVICE=\NFS\NFS5220.SYS		     │
	  │  BUFFERS=20 			     │
	  │  FILES=20				     │
	  │  LASTDRIVE=M			     │
	  └──────────────────────────────────────────┘


      b. MYEADDR.EXE  - The new myeaddr will display the Ethernet
			address of Acer 5220 Ethernet controller of
			your PC.

	 Command syntax:

	  MYEADDR controller_type [ioport_addr|shmem_addr [interrupt]]

	where:

	  1. controller_type is the option name of the Ethernet
	     controller on your system, either the A5220, A5220A,
	     3C501, 3C503, NIC, NI5010

	  2. ioport_addr is the I/O port address for A5220, A5220A,
	     3C501, 3C503 or NI5010 controllers

	  3. shmem_addr is the shared memory address for NIC card.

	  4. interrupt is the interrupt number for the controller.

	Argument 2,3,4 should be used only when the factory settings
	have been changed.

	For example:

	┌─────────────────────────────────────────────────────────┐
	│ C>MYEADDR A5220					  │
	│ Your A5220 ethernet address is: 83:1f:0:52:43:41	  │
	│							  │
	│ C>							  │
	└─────────────────────────────────────────────────────────┘

     Copy  two	files  NFS5220.SYS  and  MYEADDR.EXE from the Acer
    distribution diskette into the subdirectory \NFS. Then the old
    MYEADDR.EXE will be replaced with new one provided by Acer Inc.

     More  details  about  installation refers to ACER 5220 PC-NFS
    driver reference manual please.
