I was looking over a dmesg output and I noticed a message that said I would save 64MB of RAM if I enabled the IOMMU option in the bios. I'm using an ASUS M4A79XTD EVO board with 8GB of RAM so maybe freeing up 64MB of RAM isn't that big of a deal; however, I had a look in the bios setup and saw nothing that pertained to IOMMU to enable. The BIOS is an 8MB Flash ROM, AMI BIOS PnP etc. Can anyone eleborate on this message in dmesg? -- C --
