When it comes to opening up the computer box and doing
stuffs, I'm totally clueless (only opened up the computer
a few times and most of the times my geeky brother-in-law
did something). So I appreciate any advice you can give.
The reason for opening the box is because the internal
modem is not detected - lspci is not seeing the modem.

Earlier this year I was unsuccessful in getting the
internal modem to work.Linmodem.org said

No such PCI card is detected. There may be several
reasons.
-the card may be at the right place but not properly
installed.
-the PCI slot where you placed the card may be broken.
Try an other slot.
-you have placed a PCI modem in an ISA slot.

My questions are:
- how do one install the PCI modem card correctly?
- is there a way to tell if the PCI slot is broken?
- how can you tell if the slot is for a ISA or PCI card?

Also is there any precaution I should take (don't want to
get shocked or whatever)?

Ans1)Modem Installation.-PCI modems are provided with a driver or 'enumerator' that provides the bridge between the newer PCI bus and the traditional COM port assignments: the driver allows the system to recognize the modem as a traditional COM port with non-standard IRQ assignment.

Most PCI modems are software-based modems requiring an Operating System specific driver! There are a few - notably some USR models - hardware-controller based PCI modems - these will typically cost at least twice as much as software-based or 'Winmodem' models.

Depending upon your system design and BIOS, a conflict may prevent proper modem operation in some, but not all, of your PCI expansion slots. In addition, some vendors have motherboard BIOS updates that address PCI issues - check for updated BIOS for your system.

Ans2)PCI SLOT -Due to a race condition, a PCI slot with an empty cassette may show disconnected state rather than the usual connected state after a DR operation on a Slot 1 I/O board (hsPCI). The PCI Slot with an empty cassette should be in connected state forFRUID purposes.

Ans3)ISA OR PSA CARD- Read this article.[url]http://www.99er.net/artic.html[/url].

And as for shock prevention.Before turning on your pc and opening it to check signals be sure that the connections aren't loose and yes if there are unwanted components existing,remove them.
