Linksys Instant EtherFast® Series Note: Plug-and-Play operating systems like Windows 98, Windows 95 OSR2, (also known as Windows 95 Version B), will usually assign available I/O and IRQ values to the EtherFast 10/100 CardBus PC Card automatically, making the card's installation quick and easy. If you can't seem to find an I/O address or interrupt value to use, contact your PC's manufacturer to determine which values are currently available for use with the EtherFast 10/100 CardBus PC Card. Socket and Card Services CardBus socket and card services allow your computer to recognize a CardBus card when it is inserted into your PC's CardBus slot. Your PC will need some kind of services installed in order to use the EtherFast 10/100 CardBus PC Card. Most CardBus-equipped PCs have socket and card services pre-installed by the computer's manufacturer. If you are upgrading your PC by adding a new CardBus slot, then you need to upgrade your services as well. You have two choices: • Use Built-in Services in the Driver If your computer doesn't have services (or you don't know what kind are installed), you may be able to use the enabler built into the driver of the CardBus Card for DOS or NT computers. The enabler tries to automatically get the card recognized by the laptop and enable the slot to work with the 10/100 CardBus PC Card only. • Contact Your PC's Manufacturer If your computer doesn't have services, and the generic services contained in the 10/100 CardBus PC Card's driver don't seem to work with your PC, contact your computer's manufacturer to find out (1) what kind of services your computer uses, or (2) how to get compatible services if your computer doesn't have them. Note: Plug-and-Play operating systems like Windows 95 OSR2, 98, and 2000 have socket and card services built into the operating system. You don't need to install them if you are using these OSes. 8 EtherFast® 10/100 CardBus PC Cards How to Use the 10/100 CardBus PC Card's Enabler for DOS-Based Network Operating Systems The software disk provided with the EtherFast 10/100 CardBus PC Card includes generic socket and card services built into the driver that can be used to enable the EtherFast 10/100 CardBus PC Card. The card's hardware-specific client enabler will only enable the EtherFast 10/100 CardBus PC Card. If you want to use other PCMCIA cards in the future, you will need to obtain additional services for those card(s) before you'll be able to use them. When enabler loads itself into memory, it tries to choose IRQ and I/O base address values for the EtherFast 10/100 CardBus PC Card not already in use. Enabler also checks to see if any other service packages are loaded. If there are any services already present in memory, enabler will attempt to load itself without disturbing them. Open up your config.sys file in a text editor. Scroll through the file. Find the line that reads (or is similar to) the following: DEVICE=C:\EMM386.EXE It will probably be located near the beginning of the file. You will need to add a command to the end of the EMM386 command in order to reserve an area of memory for the 10/100 CardBus PC Card's client enabler to use. Add the following command to the end of the EMM386 line: NOEMS X=D000-D3FF so that the new EMM386 line now looks something like this (it may vary slightly): DEVICE=C:\EMM386.EXE NOEMS X=D000-D3FF If there are already commands on the EMM386 line, try not to disturb them when you add the NOEMS X=D000-D3FF Note: Plug-and-Play operating systems such as Windows 95, 98, and 2000 do not require the use of the enabler or memory exclusion. 9
