The only chipsets supported by sata_nv driver are nForce4 (CK804/MCP04) SATA controllers: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=fbbb262d9ea9bdbd79d7058271560e9990bc62d3 MCP55 isn't supported. On newer chipsets (MCP65, MCP67...) nvidia moved to AHCI. I think that if nobody with the necessary knowledge to support those chipsets like MCP55 decides to program, we'll be on our own :( unfortunately. I searched nvnews.net forum and it seems nvidia will do nothing about it... :( -- http://u-br.net Linux 2.6.20: Homicidal Dwarf Hamster gcc (GCC) 4.1.2 - To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
