		   Packet Driver Installation
		   For Ethernet+Modem PC Card

The packet driver PCMPD.COM supports both the Ethernet LAN and Modem functions 
on the Ethernet+Modem PC Card.  

PCMPD command line syntax:

PCMPD [options] <PD_INT_NO> [LAN_IRQ] [LAN_IO_BASE] [COMPORT]

where [options] are:

[-d]           The "-d" option does not start the LAN function until this 
	       driver is first called by upper layer programs.

[-n]           Your NOVELL server uses NOVELL ISO-like packets. Your NOVELL
	       workstation uses  NOVELL 8137 packets. You can use this option
	       to convert NOVELL 8137 packets into  NOVELL ISO-like packets.

[-u]           Unloads the Packet Driver.

[-h]           Displays the on-line help.

<PD_INT_NO>    Specifies the software interrupt used to load the packet 
	       driver. This value must be specified, and it must be in one of 
	       the following ranges:

	       0x60-0x66
	       0x68-0x6f
	       0x78-0x7e

	       0x67 is the EMS interrupt, and 0x70 through 0x77 are used by 
	       the second 8259 interrupt controller.  These values are thus 
	       not usable.

	       Please note the 0x in front of the value is used to indicate
	       a hexadecimal number.

[LAN_IRQ]      Specifies the interrupt (IRQ) for the LAN function.

	       All legal IRQ values are supported.  If Card Service is 
	       installed in the system, PCMPD will check with the Card Service 
	       to see if the IRQ you select is free.  If it is, PCMPD will use 
	       this IRQ.  If it is not free, PCMPD will ask the Card Service to 
	       assign an available IRQ and use that IRQ instead of the one 
	       you choose.

	       If the Card Service is not installed, PCMPD will try to use the 
	       IRQ you select regardless whether it is free.  In case 
	       the IRQ is not free, PCMPD will not come up, or the system 
	       may hang.

	       If the Card Service is installed in the system, it is recommended 
	       that you do not specify the LAN_IRQ value and let PCMPD assign
	       one for you.  If the Card Service in not installed, please make sure 
	       the IRQ you assign, or the default value (5), is not used by 
	       another device in the system.

[LAN_IO_BASE]  Specifies the base I/O address for the LAN function.

	       The supported values are:

	       0x300 (Default value)
	       0x320
	       0x340
	       0x360

	       The comment about LAN_IRQ assignment also applies to the
	       LAN_IO_BASE parameter.  If the Card Service is installed in the 
	       system, it is recommended that you do not specify the LAN_IO_BASE
	       value and let PCMPD assign one for you.  If the Card Service in not 
	       installed, please make sure the I/O Base you assign, or the 
	       default value (0x300), is not used by another device in the 
	       system.

[COMPORT]      Specifies the COM port (COM2, COM3, COM4) for the modem 
	       function.

	       The supported values are:

	       2 (for COM2)
	       3 (for COM3, default value)
	       4 (for COM4)

	       The comment about LAN_IRQ assignment also applies to the
	       COMPORT parameter.  If the Card Service is installed in the 
	       system, it is recommended that you do not specify the COMPORT
	       value and let PCMPD assign one for you.  If the Card Service in not 
	       installed, please make sure the COM port you assign, or the 
	       default value (3, for COM3), is not used by another device in 
	       the system.

Usage examples:

1) The following command loads the Packet Driver at software interrupt 
   0x60 (hexadecimal).

   PCMPD 0x60 

2) Assuming no Card Service is installed, the next command loads the 
   Packet Driver at software interrupt 60h, LAN hardware interrupt 12,  
   LAN I/O base address 0x320, and modem COM port 4 (COM4).

   PCMPD 0x60 12 0x320 4

   Please note when you specify the COM port parameter, you must also specify
   the three parameters in front of it on the command line.  

3) The next command line unloads a previously loaded packet driver.
 
   PCMPD -u

Notes:

After successfully executing PCMPD.COM, both the LAN and modem functions 
are enabled.  The command displays the Ethernet I/O port and IRQ (interrupt) 
values used by the LAN function.  It also displays the COM port (e.g. COM2, 
COM3, and COM4) in use.  Please use this COM port to configure your modem
communication software.

A sample message displayed after executing PCMPD.COM is shown as follows:

Packet driver software interrupt is 0x60  
COM3 Port: 0x3E8  IRQ 4  
I/O Port: 0x300  
Interrupt Number: 11 (0xB)
Window Memory Address Segment: 0xD000  
My Ethernet Address is 00:00:E8:01:01:58
