What are the Differences Between CardBus and 16-bit PCMCIA Cards?

CardBus is a higher performance version of a PCMCIA card. CardBus also offers lower power

consumption: CardBus Cards are all 3.3-volt cards, while 16-bit PCMCIA Cards can be 5-volt or

3.3-volt.

The key difference is the data path interface. 16-bit PCMCIA Cards are based on a 16-bit “ISA-

like” interface, while CardBus Cards use a 32-bit “PCI-like” interface. This allows the CardBus

Card to transfer data at speeds exceeding 100 Mbps, while a 16-bit PCMCIA card transfers data at

approximately 20 Mbps.

Will the GA511 Gigabit CardBus Adapter Work on My Laptop?

NETGEAR's GA511 Gigabit CardBus Adapter has a CardBus interface, so the laptop must, as

well. Most computer specifications describe the interface type (CardBus or 16-bit PCMCIA Card)

for the PC Card slots.

Alternatively, you can check the interface type in Windows by accessing the Device Manager, as

described below.

To access the Device Manager:

1. Click Start > Settings > Control Panel > System (For Windows 2000 or Windows XP, click

Start > Control Panel > System). The System Properties window opens.

2. Click Device Manager (For Windows 2000 or Windows XP, click Hardware > Device

Manager). This opens the Device Manager window.

3. Expand the PCMCIA Socket/Adapters category by double-clicking on the box with the small

plus sign. If CardBus is supported, it will be listed here. If you only see references to 16-bit

PCMCIA Card, CardBus is not supported.

How Do I Remove the GA511 Software and Utility?

You can uninstall the utility in either of the following ways:

• Go to Start > Programs > NETGEAR GA511Adapter > Uninstall GA511 utility.

• Use Add or Remove Programs in the Control Panel and remove the GA511 Gigabit CardBus

Adapter entry.

Note: Most laptops made after 1999 have CardBus slots. CardBus slots are

backwards compatible, they accept either CardBus cards (32-bit) or PCMCIA cards

(16-bit). However, a PC slot (16-bit) can only accept 16-bit PCMCIA Cards
