I am unable to install FreeBSD because of the following error
acd0: FAILURE - READ BIG_MEDIUM ERROR asc=0x21 ascq=0x00

The computer reboots during install.

I have read that this error can be due to the DVD drive being a master, 
as it is a SATA drive it is assigned as a master in the BIOS

Is there a way this can be resolved.
