Change your Bios.

Virus Warning=, set this option to disable. Itís a firmware check of the 
hard drive boot sector looking for MS/Windows boot virus. This will stop 
FBSD booting from the install CDROM or finding the hard drive.

plug-n-play=, set this option to disable. FBSD is not sensitive to 
Microsoft plug-n-play standard and may refuse to install, or cause PCI 
cards not to be found.

Disable or set to auto any BIOS option to assign IRQ numbers to PCI 
expansion slots.

Operating system type=, set to Ďotherí or any Unix type of operating 
system, donít set to MS/Windows.

Disable all power management options.

Open your box and check that the cdrom reader device is not slave on 
ribbon with no master. Freebsd assumes the motherboard primary ide 
controller has hard disk on master nipple and cdrom or another hard disk 
on slave nipple. The motherboard secondary ide controller can not have 
empty master nipple with an device on the slave nipple. If this is what 
you have, move the slave device to the master nipple and change the 
device jumper pin to indecate master.
