Hi all... I recently put my hands on a system with an ASUS P5N64 WS Pro mobo: http://www.asus.com/products.aspx?l1=3&l2=11&l3=653&l4=0&model=2182&modelmenu=1 It has a nForce 790i Ultra SLI chipset, the part for the SATA controller is MCP55. The problem is that linux seems to fail to read the hard drive on boot. I will explain. I have tried to install both CentOS 5.2 and Mandriva 2009.0. For CentOS (has a 2.6.18 kernel), the install seems ok, but when I reboot into the just intalled system the kernel hangs just after printing the name of the initrd. Mandriva (2.6.27-rc8) just hungs half the install process. Live versions of both hang on boot saying they can not find the root device. I have found some messages in the net about the MCP55 in that board not being completeley suppported as AHCI in sata_nv, and that some other boards work puttin the SATA controller in 'compatible' mode (with loss of performance). But I can't find any setting in the P5N64 to put SATA in Compat mode. Can I do this via some kernel parameters ? Somabody has this board working ? Do current kernels have better support for this chipset ? TIA -- J.A.
