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 boot configuration file)
20 "Graphics Mode"="WIDTHxHEIGHTxDEPTH" (e.g. "1024x768x32")
22 kernel flags (e.g. debug=0x144)
23 io=0xffffffff (defined in IOKit/IOKitDebug.h)
25Example: mach_kernel rd=disk0s1 -v "Graphics Mode"="1920x1200x32"
27If the computer won't start up properly, you may be able to start it up
28using safe mode. Type -x to start up in safe mode, which ignores all
29cached driver files.
31Special booter hotkeys:
32 F5 Rescans optical drive.
33 F10 Scans and displays all BIOS accessible drives.
35Special booter commands:
36 ?memory Displays information about the computer's memory.
37 ?video Displays VESA video modes supported by the computer's BIOS.
38 ?norescan Leaves optical drive rescan mode.
