3Com (R) Corporation 3C90x EtherLink PCI NIC Family Clarkson Packet Driver Installation Notes EtherLink PCI Packet Driver ---------------------------- A 3Com EtherLink PCI NIC is completely configured through software. You can load the driver from the command line or in the AUTOEXEC.BAT file. When the packet driver is loaded, the only required command line option is the software interrupt value (/I). The software interrupt is used to communicate between the driver and the protocol and should not be confused with the NIC's hardware interrupt. In version 1.10 of the Packet Driver Specification, valid software interrupt values are in the range 0x20 to 0x80. In version 1.09, valid software interrupts are in the range 0x60 to 0x80. Loading the Driver from the AUTOEXEC.BAT File --------------------------------------------- To load the driver from the AUTOEXEC.BAT file, copy the driver from the PKTDVR directory on the EtherCD (or EtherDisk 2 diskette) to your hard drive. You must either place the driver in your path or use the full pathname in the AUTOEXEC.BAT file. Loading the Driver from the Command Line ---------------------------------------- To load the driver from the command line, use the following syntax: 3C90XPD [switches] [options] Switches -------- The driver supports the following switches: -? = Show usage -u = Uninstall driver -n = Novell NetWare conversion -d = Delay initialization (for diskless booting) -t = Disable transmit Parallel Tasking (R) feature -r = Disable receive Parallel Tasking feature -m = Maximize PCI latency timer The -n switch is needed if the packet is in Ethernet encapsulated IPX format and it needs to be converted to 802.3 format. The default is 802.3 format. The -t switch disables the NIC's early transmit feature. The default is enabled. The -r switch disables the NIC's early receive indications feature. The default is enabled. Options ------- The driver supports the following options: /I = software interrupt (20h -FFh); default = 60h /S = slot number (0 - 31 for PCI) /K = bus number (0 - 7 for PCI) You must specify the bus type if the bus number and the slot number are used. The bus number is used specifically for PCI. Example ------- The following example shows a typical command line. If you want to load the driver at software interrupt 60h with receive Parallel Tasking feature disabled, a PCI bus type, slot number = 1, and PCI bus number = 0, the command line should look like this: 3C90XPD -r /S=1 /K=0 /I=60 For a complete summary of usage guidelines, type at the command line: 3C90XPD -?

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.
