As root in a console window /etc/init.d/alsa-autoconfig to setup the alsa devices then edit the file /etc/init.d/bootmisc.sh and put the line aumix -w 75 -v 75 at the bottom of the file for the volume to be set at boot time. For the network card make sure the file /etc/network/interfaces looks like this:

Code:
 # /etc/network/interfaces -- configuration file for ifup(8), ifdown(8)

 # The loopback interface
 auto lo
 iface lo inet loopback

 # The first network card - this entry was created during the Debian installation
 # (network, broadcast and gateway are optional)
 auto eth0
 iface eth0 inet dhcp
Then /etc/init.d/networking restart to re-start the network with the new settings. You may still need the noapic in the GRUB config but I can't be much help there never use it.
