The hardware notes for CURRENT show the following: SiS 530, 540, 620 SiS 630, 633, 635, 645, 730, 733, 735, 740, 745, 750 SiS 5591 ATA100 ...so the controller is technically unsupported. The controller in question is integrated on an MSI motherboard, model MS-6533E. If you boot such a host with a 4.4R or 5.0-DP1 cdrom, it gets to the "Probing devices" splash screen and then hangs forever. With a 4.7R disc, you get to see the actual messages: ad0 READ command timeout tag=0 serv=0 - resetting ata0: resetting devices .. However, it can be made to work. Disabling UltraDMA in the BIOS will allow one to use this controller, at least under 4.7-RELEASE. A bit suboptimal, but far better than nothing.
