I assume you mean "Asus CDRW" there. newbie, it's hard for us to give you a complete set of BIOS settings in a place such as this, there are typically so many variables. Fortunately with so few devices in your box, if the P4PC800 BIOS is anything like the P4C800-E, almost all the defaults will work fine for you.P4 2.4Ghz 800Mhz
512Mb PC3200 Kingston value RAM x1
Hercules 3D Prophet 9600 Pro 128 Mb
Maxtor 40GB HDD
After setting time/date, I would make sure the Boot-- Boot Device Priority is set to CD-Floppy-HDD, that's the minimum you should need to do. Personal preference, I would also disable the HyperThreading if it's not grayed out. If you hook up more peripherals later, there may be more adjustments at that time.
