X-BeenThere: freebsd-amd64@freebsd.org X-Mailman-Version: 2.1.1 Precedence: list List-Id: Porting FreeBSD to the AMD64 platform List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Tue, 25 Nov 2003 03:29:01 -0000 Are there any ATA or serial-ATA controllers that can address memory above 4 GB? In other words I'm hoping to avoid bounce-buffers with large memory configurations. I believe there are SCSI controllers that can do this but I'd rather stick to ATA or sATA for cost reasons. HighPoint has released the RocketRAID 1820, which is a serial-ATA PCI-X 64-bit 66/100/133 MHz controller with eight sATA ports. I have no idea if it can address memory above 4 GB not.
