Chameleon Svn Source Tree


1The boot: prompt waits for you to type advanced startup options.
2If you don't type anything, the computer continues starting up normally. It
3uses the kernel and configuration files on the startup device, which it also
4uses as the root device.
6Advanced startup options use the following syntax:
8 [device]<kernel> [arguments]
10Example arguments include
12 device: rd=<BSD device name> (e.g. rd=disk0s2)
13 rd=*<IODeviceTree path> (e.g. rd=*/PCI0@0/CHN0@0/@0:1)
15 kernel: kernel name (e.g. "mach_kernel" - must be in "/" )
17 flags: -v (verbose) -s (single user mode)
18 -x (safe mode) -f (ignore caches)
19 -F (ignore "Kernel Flags" specified in boot configuration file)
21 "Graphics Mode"="WIDTHxHEIGHTxDEPTH" (e.g. "1024x768x32")
23 kernel flags (e.g. debug=0x144)
24 io=0xffffffff (defined in IOKit/IOKitDebug.h)
26Example: mach_kernel rd=disk0s1 -v "Graphics Mode"="1920x1200x32"
28If the computer won't start up properly, you may be able to start it up
29using safe mode. Type -x to start up in safe mode, which ignores all
30cached driver files.
32Special booter hotkeys:
33 F5 Rescans optical drive.
34 F10 Scans and displays all BIOS accessible drives.
36Special booter commands:
37 ?memory Displays information about the computer's memory.
38 ?video Displays VESA video modes supported by the computer's BIOS.
39 ?norescan Leaves optical drive rescan mode.
41Additional useful command-line options:

111 EnableC4State=Yes Enable specific Processor power state, C4.
113 SMBIOS=<file> Use an alternate SMBIOS.plist file
114 (default paths:
115 /Extra/SMBIOS.plist bt(0,0)/Extra/SMBIOS.plist).
