hughythomas Posted December 23, 2009 Share Posted December 23, 2009 I am currently using Snow Leopard 10.6 and I need to boot 32 bit as my UAD-2 card will not load up unless its 32bit. When I typed "ioreg -l -p IODeviceTree | grep firmware-abi" into the console it returned EFI64bit. Is there a way of booting 32bit somehow? I use vanilla Snow Leopard and installed using this guide: http://leeyuentuen.hostei.com/?p=662 Also my com.apple.plist looks like this: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>Graphics Mode</key> <string>1280x1024x32</string> <key>Kernel</key> <string>mach_kernel</string> <key>Kernel Flags</key> <string>arch=x86_64, -v</string> <key>UHCIreset</key> <string>n</string> <key>GUI</key> <string>n</string> <key>GraphicsEnabler</key> <string>n</string> <key>ForceWake</key> <string>n</string> <key>Timeout</key> <string>4</string> <key>ForceHPET</key> <string>n</string> <key>EthernetBuiltIn</key> <string>n</string> <key>EHCIacquire</key> <string>n</string> <key>device-properties</key> <string>6c0200000100000001000000600200000d00000002010c00d041030a000000000101060000010 101060000007fff04001e00000072006f006d002d007200650076006900730069006f006e0000002e 0000006e5669646961204765466f7263652037333030204753204f70656e474c20456e67696e65205 b4546495d22000000400030002c006400650076006900630065005f00740079007000650000000b00 0000646973706c6179100000004e00560043004100500000001800000004000000000003000c00000 000000007000000000e0000006e0061006d00650000000b000000646973706c617914000000400030 002c006e0061006d0065000000120000004e5644412c446973706c61792d41100000006d006f00640 065006c0000001a0000006e5669646961204765466f72636520373330302047530e0000004e005600 50004d000000200000000100000000000000000000000000000000000000000000000000000014000 000400031002c006e0061006d0065000000120000004e5644412c446973706c61792d422000000040 0031002c0063006f006d00700061007400690062006c00650000000e0000004e5644412c4e564d616 3220000005600520041004d002c0074006f00740061006c00730069007a0065000000080000000000 001020000000400030002c0063006f006d00700061007400690062006c00650000000e0000004e564 4412c4e564d616322000000400031002c006400650076006900630065005f00740079007000650000 000b000000646973706c61791c0000006400650076006900630065005f00740079007000650000000 f0000004e5644412c506172656e74</string> </dict> </plist> I see theres an x86-64 string maybe this is relevant?

MacUser2525 Posted December 23, 2009 Share Posted December 23, 2009 I see theres an x86-64 string maybe this is relevant? Thanks in advance! Tom It is change it to arch=i386 for 32 bit.
