intel i810 sound card & motorola sm56 int. modem config

[Gnanaskandan Rajagopalan]

Hello,
i am new to freebsd and i installed freebsd4.10 on my system with
great difficulty. it wudnt display GUI properly. i had to do xconfig a
lot of times but still it failed. Frustrated, i switched off the comp
and when i switched it back on, it was working. KDE is running by
default. i installed most of the packages during the install.
1. Is there any list like windows add/remove programs list where i can
see what programs i have installed? How do i change the default GUI or
such applications? Guess that shouldn't be difficult and if i look
around properly, i should find it.
2. How do i configure the sound card? i have intel 810 chipset. and
AC97 on-board audio controller.
3. I have an internal modem which didn't get installed. And i cant
kppp dialer because of that. It is a winmodem. The model is sm56 by
motorola. I had lots of probs installing this modem in RedHat9 long
back.
I wud be glad if someone can help me with these.
