I've got a 15" MacBook Pro, mid 2009 (MacBookPro5,3) with the Nvidia MCP79. Just wanted to report success using the following method: 1. In Device Manager, find the Standard Dual Channel PCI IDE Controller. 2. Choose 'Update Driver Software', 'browse ...', 'let me pick ...'. 3. Uncheck 'Show compatible hardware'. 4. Choose 'Standard AHCI 1.0 Serial ATA Controller' in the manufacturer list, and the same for model (should be the only model) Finally, in the registry, check that in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\msahci Start is set to 0. Note: only do this with a MCP79! Normally, forcing a driver on hardware it doesn't expect is dangerous. However, in this case, it appears to be safe. I've found that Linux can use AHCI on MCP79 in legacy IDE mode, and this is why: http://fixunix.com/kernel/258426-patch-ahc...ler-ahci-c.html
