10
12 bootconf is a small utility that provides a convenient way to set or
13 inspect some common Linux kernel boot options. bootconf updates the
14 GRUB configuration file (/boot/grub/grub.conf in most cases). The
15 changes will take effect, naturally, at the next reboot.
16
17 The following parameters may be specified:
18
19 -titles
20 This parameter must be specified by itself, alone. bootconf
21 displays a formatted list of available boot partitions and kernels.
22
23 default=n
24 The default boot kernel or partition is “n”, where “n” is the boot
25 partition number from the list produced by the -titles parameter.
26
27 quiet or quiet=1
28 Suppress most diagnostic messages when the Linux kernel
29 initializes.
30
31 noquiet or quiet=0
32 Display diagnostic messages when the Linux kernel initializes.
33
34 gui or gui=1
35 Show the status of the system boot process graphically (the “rhgb”
36 boot option).
37
38 nogui or gui=0
39 Show the status of the system boot process as text.
40
41 vesa=mode
42 Use a VESA framebuffer for the system display (see below).
43
44 novesa
45 Do not use the VESA framebuffer for the system display.
46
47 Running bootconf without specifying any parameters displays the current
48 settings. Run bootconf from X to show a small window where the
49 individual settings can be adjusted graphically.
50
51 The current settings are parsed from the first kernel listed in GRUB´s
52 configuration file, but new settings are saved for every configured
53 kernel.
54
55 VESA framebuffer
56 Many modern video cards are capable of providing a standard,
57 vendor-independent access mechanism to the display memory. Linux can
58 use this framebuffer for the system console, as opposed to the
59 traditional text display.
60
61 The “vesa=mode” option configures the Linux kernel to set the video
62 card framebuffer to mode. The possible values for mode are:
63
64 640x480x8 640x480x15 640x480x16 640x480x24 800x600x8 800x600x15
65 800x600x16 800x600x24 1024x768x8 1024x768x15 1024x768x16 1024x768x24
66 1280x1024x8 1280x1024x15 1280x1024x16 1280x1024x24 1600x1200x8
67 1600x1200x15 1600x1200x16 1600x1200x24
68
69 Note
70 Your video card may not support all of the above video modes. Check
71 your video card´s documentation. If you select an invalid video mode,
72 the Linux kernel may not be able to boot. When that happens, press E to
73 edit the kernel command line, in GRUB, remove the “vga=NNN” parameter,
74 press Enter then B to boot without the framebuffer.
