U.S. Robotics 10/100 PCMCIA NIC TX
Packet Driver Installation
1. Enable the U.S. Robotics 10/100 PCMCIA NIC TX
USROPEN.EXE is the U.S. Robotics 10/100 PCMCIA NIC TX MS-DOS enabling program. You
have to run USROPEN.EXE to enable U.S. Robotics 10/100 PCMCIA NIC TX before bringing up
the packet driver.
The syntax for USROPEN is:
USROPEN [/IRQ=x] [/MEM=mm] [/IO=nnn] [/O] [/?]
Valid options:
x = Interrupt number (3, 4, 5, 9, 10, 12, 15).
This number must not be in use by any other device in the system.
mm = Hex memory location (e.g. C0, C8, D0, D8).
nnn = IO range (300, 320, 340, 360).
U.S. Robotics 10/100 PCMCIA NIC TX requires 32 consecutive free I/O port addresses.
/O (overwrites current socket settings).
/? Displays this screen.
The default value for IRQ is 3. The default value for IOP is
0x300.
Example: The following command enables U.S. Robotics 10/100 PCMCIA NIC TX with IRQ 5 and
I/O port address 300:
USROPEN /IRQ=5 /IO=300
If you installed EMM386.EXE in CONFIG.SYS, please exclude memory
address range D000-DFFF or D400-D7FF from EMM386.EXE. The
U.S. Robotics 10/100 PCMCIA NIC TX DOS enabler USROPEN.EXE uses this space to read
Ethernet ID and CIS from on-board flash memory.
[Example]
DEVICE=EMM386.EXE NOEMS X=D000-DFFF
2. Load the DOS Packet Driver USRPCM
USRPCM syntax:
USRPCM [-u] [-a] [-media] <PACKET_INT_NO> <INT_LEVEL> <IO_ADDR>
Where:
u -- Unstall the driver.
a -- Enable Auto-Negotiation Mode.
media -- To set LineSpeed and Duplex.
The vaild setting is 10half, 10full, 100half or 100full.
10half -- Forced to 10M, HalfDuplex Mode
10full -- Forced to 10M, FullDuplex Mode
100half -- Forced to 100M, HalfDuplex Mode
100full -- Forced to 100M, FullDuplex Mode
PACKET_INT_NO -- Packet driver interrupt vector.
The reasonable rabge is 0x60 to 0x80
INT_LEVEL -- Hardware interrupt number.
IO_ADDR -- I/O Port Address.
The only required parameter is the packet driver interrupt. A packet
driver needs to have a software interrupt assigned to it for other
programs to access it.
PACKET_INT_NO This parameter specifies the software interrupt
where the packet driver is loaded. It must be in
the range 0x60 to 0x80.
This is a required parameter.
The value you specified for this parameter
must start with 0x to indicate this is a
hexadecimal value.
[INT_LEVEL] This specifies the hardware interrupt (IRQ)
value.
Note that this value must match the IRQ value
you specified for USROPEN.EXE or the one
reported by USROPEN.EXE.
[IO_ADDR] This specifies the starting I/O address.
The value you specified for this parameter
must start with 0x to indicate this is a
hexadecimal value.
Note that this value must match the IOP value
you specified for USROPEN.EXE or the one
reported by USROPEN.EXE.
Example 1:
The following command loads the U.S. Robotics 10/100 PCMCIA NIC TX Packet Driver at
software interrupt 0x60, I/O address 0x300, and hardware
interrupt 3.
Since no command line option is specified, the connection
type is set to Auto-negotiation.
USRPCM 0x60 3 0x300
Example 2:
The following command loads the U.S. Robotics 10/100 PCMCIA NIC TX Packet Driver at
software interrupt 0x60, I/O address 0x320, and hardware
interrupt 5, and the linespeed forced to 10Full.
USRPCM -10FULL 0x60 5 0x320
Example 3:
The following command unloads the U.S. Robotics 10/100 PCMCIA NIC TX Packet Driver.
USRPCM -u 0x60
A sample batch file START.BAT is included in this directory. This
batch file first executes USROPEN.EXE and then brings up the packet
driver. To use this batch file on your computer you may
have to modify the IRQ and IO_BASE values.
Download Driver Pack
After your driver has been downloaded, follow these simple steps to install it.
Expand the archive file (if the download file is in zip or rar format).
If the expanded file has an .exe extension, double click it and follow the installation instructions.
Otherwise, open Device Manager by right-clicking the Start menu and selecting Device Manager.
Find the device and model you want to update in the device list.
Double-click on it to open the Properties dialog box.
From the Properties dialog box, select the Driver tab.
Click the Update Driver button, then follow the instructions.
Very important: You must reboot your system to ensure that any driver updates have taken effect.
