Here is a copy of a message I sent to trendnet:
I have an old ibm thinkpad 760cd. I am running a clean install of win
98 se, All the junk from IBM is gone. Only 98 is on hard drive. No
matter how many times I try, I cannot get the TEW-226pc installed. I
follow the instructions to the letter when I install the software on
on the cd. When I reboot with the card in place, however, it is never
found by plug and play. I do get an unknown device found message, I
know the Trendware card is inexpensive and that you are very busy.
Still, I hope that you can give me some advice, I have been working on
this for two days. Thanks for anything you may recommend.

I also realize that the 760cd is old, but it would be a blessing if I
could add it to a wireless network. Any tips or help will be most
helpful. Thanks!!!

Unfortunately, the problem here is not with the driver, or with the
installation. The problem is a hardware incompatibility. Your IBM
Thinkpad 760CD (a design dating from 1995) has two PCMCIA Type II
slots. These are designed for 16-bit PCMCIA cards. The TEW-226PC is a
32-bit CardBus PC Card adapter. This is not backwards-compatible with
the 16-bit PCMCIA slots on your Thinkpad. You can differentiate a
CardBus adapter from a PCMCIA adapter by looking at the connector-end
of the card; if there is a (usually gold-coloured) metal plate with
bumps on it on the 'top' (ie. logo-sticker) side of the card, then it
is a CardBus adapter.

If you can return the TEW-226PC card to the retailer where you
purchased it, I suggest that you do so. Unfortunately, it is extremely
difficult to find any wireless adapters these days that are 16-bit
PCMCIA compatible, especially ones as affordable as the TEW-226PC.
However, here are some options for you to consider:

Belkin F5D6020

Actiontec HWC01150-01

Micro Plus MP-C100

Wave Buddy 802.11b

As the market for 16-bit PCMCIA wireless adapters is rapidly
diminishing, these cards may be difficult to find in stock. As well,
given the limitations of the 16-bit interface, you will not find any
802.11g adapters that would work in your laptop.

I hope that this Answer helps, and best of luck in finding an adapter
that helps you "cut the cord"!
