Both. The memory controller and the DIMMs have to support it, and the BIOS
has to configure the memory controller to enable it.

I have a 1GB sticks of HP SDRAM PC133 SDRAM ECC.  The system is a Netgear 
ND520 Network Disk Drive.  The BIOS does not support ECC.  How would I find 
out if the memory controller supports ECC? All my googling says no.

I found the ND520 at a garage sale for $20.  Currently it only supports up 
to 128MB ram and nothing bigger then a 36GB hard drive (IDE); and the real 
fun part... No console connection any wear that I can find. Netgear stopped 
supporting these a few years ago. I was able to quickly rebuild the system 
running Gentoo Linux, I now moves VERY fast, for what it is.

Do we have support for Linux BIOS on this chip set VT82C585VP?

Here is the information I get from lspci -vv
