So far for the good news. There's still some more hardware on this laptop, but this is all I got to work. What follows is some other hardware that may work, but that I either didn't even try to get it to work, or that I did try, but gave up because I lost interest because I probably won't use that particular bit of hardware in the near future anyway.
That doesn't mean I wouldn't like getting it to work. If you know or find out how to get one of those to work, let me know.
The modem is a Lucent SoftModem (scorpio). According to different sources on the web, this softmodem is not currently supported (http://www.idir.net/~gromitkc/agere/agere_LU97.html). Buy a pcmcia card if you need a modem or write down a driver (personaly, i don't have the necessary knowledge).
An SD Card (Secure Digital Card) seems to be a CompactFlash-like thing. This laptop has a slot to read it, but only supports one of the types of cards that can be put into this type of slots.
Since I don't have any of those cards, I don't use them. Or the slot. Didn't try to get it to work.
There's one pretty confusing message box when you use the ``extreme long battery life'' setting in the ``Power Saver'' control panel under the preinstalled Windows, and use the laptop on battery power. It's got a title saying ``IEEE 1394'', while the text of the message box is a question asking something about some devices being shut down, and whether or not you agree on that.
This may lead one to think that there's some FireWire-hardware in this laptop, since IEEE 1394 is the document that describes that standard. There's no FireWire in this laptop, though. I suppose this is some bug in Windows (big surprise, there): the message refers to the network card being shut down.
Oh well, why not.
