Latitude D630 drivers install help

Hello... I just used the restore disc for my dell latitude D630 Then installed drivers in this order

1. System Utilities - Dell-Utility R181862.exe

2. Chipset - Intel-Driver R153997.exe

3. Video - nVidia-Driver R224634.exe

4. Audio - SIGMATEL-Driver R171789.exe

5. Input - Dell-Driver R165804.exe

6. Network - Dell-Driver DELL_MULTI-DEVICE_A31-1_R286815.exe


After drivers installed I looked in Devise Manager and it shows this...
yellow question mark - Other devices
yellow question mark - Ethernet Controller
yellow question mark - Modem Device on High Definition Audio Bus
yellow question mark - O2Micro CCID SC Reader

How would I get the yellow question mark's to be correct ?

Also while i'm at it I would like to install the latest drivers.. what drivers are the drivers to get and what order?

I seen a driver for BIOS Dell-BIOS D630_A17.EXE Release Date 1/22/2010 would I install that one ?

My goal is turn my laptop into A DAW for DJing

Any help would be appreciated

Thanks
