A high speed alternative for SCSI harddrives. The performance of SATA-1 compliant devices is equivalent with 10,000 RPM SCSI drives (Ultra160/Ultra320).
FedoraCore 1 recognises this hardware when booting from CD. It will also will happily install/boot to/from a 160 GB SATA HDD from CDROM after it recognises and configures the Silicon Images PCI card.
It seems that there's a 2.4.x patch, the driver is in 2.6, and there's a binary driver provided as well. Read about the SiL3112A Linux driver thread at LinuxQuestions.
