ECC and NON ECC RAM is supported on your board but you do not need to change anything in the BIOS, it should detect it automatically. If you have replaced the memory and the system won't boot you will want to verify you have at least two RIMMs inserted or you will need C-RIMM (Continuity RIMM) modules inserted into the empty slots. Also it looks like your board will support up to 2GB total memory (PC800 and PC1066 is supported).
Let me know if this helps or not, if not give me more of an idea what the system is or is not doing.
