Problem in installing modem & audio XP driver

Hi,

I installed a clean XP Pro on my laptop and then tried to install drivers that are obtainable from Toshiba site.
Everything worked except Modem and Sound drive. They both have a PCI DEVICE exclamation mark on device manager's Other Devices section.

I tried downloading several drivers but none worked so far.

I don't have access to my recovery disc since I moved here for a one month job.

got drivers from USA web site and tried them after the SP2 (but didn't find any hotfix since I assumed they are contained in SP2) and even installed Intel's Chipset before installing the drivers since that was more logical (cuz I'm a software eng. myself)

The strange thing is that whenever I install windows on this laptop, after the first boot, it would recognize audio and would playback a standard sound out of it (a.k.a. sound works but not at its best) and I had to install RealTek's to enhance it but now I don't have that basic sound.

Another thing that is bothering me is showing (probably) sound and modem as "PCI DEVICES" in control panel and doesnt even recognize what type of devices they are.

And last thing is when I install the modem driver (and I tried 3 different ones), the progress bar goes really slowly and when it reaches like 80%, it just dissappears.


Thanks in advance.
