Before installing LINUX. You need to change a few settings in the BIOS.
1) If PNP OS is enabled, change it to disable. Windows will still work but you can no change the IRQs of the devices within Windows.
2) ACPI also needs to be disable. Windows will still work if this is off. Both Windows and LINUX will use APM. Windows 2000 and Windows XP has a problem using APM when you trying to shut it down. Microsoft has a fix.
3) If AGP is at 4X or 8X, change it to 2X preferrely 1X.
4) Change all memory settings to their normal non agressive modes. This means change Front Side Bus speed to 100 MHz and changing CAS 2 to CAS 3.
Steps 3 and 4 should done on every OS installation for the least amount of trouble.
jfrey, for your on-board NIC. You need to know the brand and model of your NIC before you set it up in LINUX. Usually on-board NICs are from Realtek and others are from 3com. You can easily download the linux drivers and set it up. To setup the driver. Log in to any user and at the console type su. Next type your root's password. Read the instructions on how to install the drivers. Don't forget to add a line in /etc/modules.conf if the driver works.
I forgot to list a good LINUX newbie site in my previous post.
