1 | The boot: prompt waits for you to type advanced startup options.␊ |
2 | If you don't type anything, the computer continues starting up normally. It␊ |
3 | uses the kernel and configuration files on the startup device, which it also␊ |
4 | uses as the root device. ␊ |
5 | ␊ |
6 | Advanced startup options use the following syntax:␊ |
7 | ␊ |
8 | [device]<kernel> [arguments]␊ |
9 | ␊ |
10 | Example arguments include␊ |
11 | ␊ |
12 | device: rd=<BSD device name> (e.g. rd=disk0s2)␊ |
13 | rd=*<IODeviceTree path> (e.g. rd=*/PCI0@0/CHN0@0/@0:1)␊ |
14 | ␊ |
15 | kernel: kernel name (e.g. "mach_kernel" - must be in "/" )␊ |
16 | ␊ |
17 | flags: -v (verbose) -s (single user mode), ␊ |
18 | -x (safe mode) -F (ignore boot configuration file)␊ |
19 | ␊ |
20 | keystrokes :␊ |
21 | F8 Abort quiet mode, and display the menu.␊ |
22 | alt+f Old safe mode␊ |
23 | shift+f Ignore boot configuration file␊ |
24 | alt+s Single user mode ␊ |
25 | alt+v Verbose␊ |
26 | alt+x Safe mode␊ |
27 | alt+l Legacy mode (not sure why you need this)␊ |
28 | 6+4 64-bit␊ |
29 | 3+2 32-bit␊ |
30 | ␊ |
31 | "Graphics Mode"="WIDTHxHEIGHTxDEPTH" (e.g. "1024x768x32")␊ |
32 | ␊ |
33 | kernel flags (e.g. debug=0x144)␊ |
34 | io=0xffffffff (defined in IOKit/IOKitDebug.h)␊ |
35 | ␊ |
36 | Example: mach_kernel rd=disk0s1 -v "Graphics Mode"="1920x1200x32"␊ |
37 | ␊ |
38 | If the computer won't start up properly, you may be able to start it up ␊ |
39 | using safe mode. Type -x to start up in safe mode, which ignores all ␊ |
40 | cached driver files.␊ |
41 | ␊ |
42 | Special booter hotkeys:␊ |
43 | F5 Rescans optical drive.␊ |
44 | F10 Scans and displays all BIOS accessible drives.␊ |
45 | ␊ |
46 | Special booter commands:␊ |
47 | ?memory Displays information about the computer's memory.␊ |
48 | ?video Displays VESA video modes supported by the computer's BIOS.␊ |
49 | ?norescan Leaves optical drive rescan mode.␊ |
