SMC EZ Card 10/100 (SMC1255FTX-SC)
Packet Driver Installation
The driver SMCPKT.COM can be used for the following:
SMCPKT syntax:
SMCPKT [-#] [-a] [-t] [-v] [-f] [-s] [-n] [-w] [-u] [-h] <PD_INT_NO>
Parameter Explain
------------------------------------------------------------------------
[-#] The "-#" option will let the driver work on a specific adapter
when multiple SMC1255FTX-SC based adapters are found in the computer
system. For example, "-1" means the first adapter will be
activated by the driver, "-2" means the second adapter will
be activated, ... etc.
A maximum of 4 adapters are supported simulaneously.
[-a] The "-a" option will let driver perform automatic media
detection during driver initialization. The detection
sequence is
TP 100Mbps Full Duplex ---> TP 10Mbps Full Duplex --->
TP 100Mbps Half Duplex ---> TP 10Mbps Half Duplex
If no UTP RJ45 is attached to the adapter and FIBER SC connector
is attached to the adapter then FIBER 100Mbps Full Duplex
will be usedas default media.
If no physical media is attached to the adapter then TP
100Mbps Full Duplex is the default media.
[-v] The "-v" option is to use FIBER (SC connector) as the transmission media.
There are two mode can be implemented under FIBER media.
<FX 100Mbps Half Duplex> and <FX 100Mbps Full Duplex> can be specified.
If forcing FX 100Mbps Half Duplex is desired, only -s option need to
be added after -v option and no -f option, such as following:
SMCPKT -v -s 0x60
Similar, forcing FX 100Mbps Full Duplex can be obtained by
following command:
SMCPKT -v -s -f 0x60
[-t] The "-t" option is to use Twisted Pair (RJ-45) (10BASE-T) as
the transmission media. And it is also the default setting.
[-f] The "-f" option enables FULL_DUPLEX feature of the adapters.
It has effect whether Twisted Pair or SC connector is in use.
[-s] The "-s" option sets the adapter line speed to 100Mbps.
[-u] This option unloads the Packet Driver.
[-h] This option displays the on-line help.
<PD_INT_NO> This specifies the software interrupt (INT) where you'll
load the packet driver. It must be in the range 0x60 to
0x80. Remember to add prefix of "0x" to the parameters.
Notice: The PC/TCP kernel, by default, is loaded at
interrupt 0x61 (so don't load the packet driver
there!)
------------------------------------------------------------------------
Example:
1. Load this Packet Driver at software interrupt 60h,
transmission media is automatical-detected:
SMCPKT -a 0x60 or SMCPKT 0x60
2. Load this Packet Driver at software interrupt 60h,
transmission media is 10M HalfDuplex:
SMCPKT -t 0x60
3. Load this Packet Driver at software interrupt 60h,
transmission media is 10M FullDuplex:
SMCPKT -t -f 0x60
4. Load this Packet Driver at software interrupt 60h,
transmission media is 100M HalfDuplex:
SMCPKT -s 0x60
5. Load this Packet Driver at software interrupt 60h,
transmission media is 100M FullDuplex:
SMCPKT -s -f 0x60
6. Load this Packet Driver at software interrupt 60h,
transmission media is Fiber 100M:
SMCPKT -v 0x60
7. Load this Packet Driver at software interrupt 60h,
transmission media is Fiber 100M FullDuplex:
SMCPKT -v -f 0x60
8. Unload this Packet Driver
SMCPKT -u
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.
