This README file is for the installation of Digital Equipment
Corporation's EtherWORKS Turbo PCI 10 adapter using a Packet
Driver.

Supported adapters:
	DE450

Device driver: DE450.COM

This document contains the following sections:

	1. Invoking the Packet Driver
	2. Command Line Parameters


******************************
* INVOKING THE PACKET DRIVER *
******************************

The driver can be invoked using the following command:

  DE450.COM i:[0x]<Software Interrupt> [p:<PCI Adapter No>] 
	   [m:<Medium Mode>] 
	   [t:<Medium Type>]
	   [u:[[0x]<Unloaded Software Interrupt>]]
 
  Example:      de450 i:0x60 p:1 m:10H t:T
		de450 u:0x60

  After this command is invoked the Packet Driver will search for 
  the specified adapter and, if successful, load itself as a TSR.
  A Packet Driver application can then be invoked.  

  If problems occur, please make sure: 
	
	o The Software Interrupt vector does not match one that is 
	  already loaded.

	o In systems that have user-configurable PCI parameters,
	  the PCI slot must be enabled and bus master DMA must be
	  enabled. Also, an acceptable IRQ number must be assigned.

	o Make certain the software interrupt vector is not in use
	  by another program.  The following should be avoided:

		* 0x67 can be used by EMS memory manager functions
		* 0x70 - 0x77 can be used to access IRQs 8 - 15
			    

***************************
* COMMAND LINE PARAMETERS *
***************************

Software Interrupt (required)
  i:[0x]<Software Interrupt> is a necessary parameter to invoke 
  this driver. <Software Interrupt> is a hex number from 60 to 80 
  (inclusive).  Software interrupt vector 60, which is the usual 
  choice, can be used. 
  
  Examples:     de450 i:60
		de450 i:0x60

  *NOTE*: Be careful when choosing a software interrupt vector as 
	  not to use one that is in use by another program. The 
	  following should be avoided:

		o 0x67 can be used by EMS Memory manager functions
		o 0x70 - 0x77 can be used to access IRQ's 8 - 15

PCI Adapter Number (optional)
  p:<PCI Adapter No> can be any one of 0-4 (inclusive).  It is used 
  to choose the adapter that you want to run this driver on if 
  there are two or more supported adapters on your system at the 
  same time. 
  
  If this parameter is not included on the command line, the driver
  will auto-scan the PCI slots to search for a supported adapter,
  and will use the first supported adapter found.

  If this parameter is set to zero, will auto-scan exactly as if 
  the parameter were not present.

  Examples:     de450 i:60 p:0
		de450 i:60 p:2

Medium Mode (optional)
  m:<Medium Mode> can have the value 10H or 10F.
  
  10H   10Mbps half-duplex
  10F   10Mbps full-duplex

  If this parameter is not assigned, the driver will auto-detect 
  the network medium which this adapter is attaching to and match 
  it.

  If this parameter is specified, the medium type will be assumed 
  to be Twisted Pair unless the <Medium Type> parameter is 
  specified.

  Example:      de450 i:60 m:10H

Medium Type (optional)
  t:<Medium Type> can be any one of T, A, and B. 
  
  T     Twisted-Pair
  A     AUI
  B     BNC
  
  If this parameter is not assigned, the driver will auto-sense 
  this adapter to decide a proper medium type to connect to the
  network.  

  Examples:     de450 i:60 t:T
		de450 i:60 t:B

Unloaded Software Interrupt (optional)
  u:<Unloaded Software Interrupt> can be a hexadecimal number from 
  60 to 80 (inclusive).  It should be the software interrupt number
  of the driver you want to unload.  If a number is not specified,
  the first Packet Driver found from interrupt 0x60 to 0x80 will be
  unloaded.

  Examples:     de450 u:
		de450 u:0x60
		de450 u:60
