Загрузчик (Boot Loader)

Haiku's Boot Loader Options can help when you experience hardware related problems or want to choose which Haiku installation to start, if you have more than one (maybe on an installation CD or USB stick). It's also handy if you have installed a software component that acts up and prevents you from booting Haiku, see Troubleshooting below.

Для того чтобы зайти в настройки загрузчика, необходимо нажать и удерживать клавишу SHIFT до начала загрузки Haiku. Если загрузчик установлен, то вы можете начать удерживать SHIFT перед выбором загрузочной записи Haiku, а если она является единственной операционной системой на компьютере, то вы можете начать удерживать клавишу во время стартовых сообщений BIOS.

index Опции загрузчика

Вы увидите три пункта меню:

Выбор загрузочного раздела
(Select boot volume)
Choose which Haiku installation/state to start (see Troubleshooting below).
Выбор опций безопасного режима
(Select safe mode options)

Здесь находится несколько опций, которые могут помочь с решением аппаратных проблем или же побороть нестабильную работу системы в случае некорректно ведущего себя адд-она. При выборе опции в нижней части экрана отображается её краткое описание.

Safe mode
Puts the system into safe mode. This can be enabled independently from the other options.

Disable user add-ons
Prevents all user installed add-ons from being loaded. Only the add-ons in the system directory will be used. See Troubleshooting below.

Disable IDE DMA
Disables IDE DMA, increasing IDE compatibility at the expense of performance.

Ignore memory beyond 4 GiB
Ignores all memory beyond the 4 GiB address limit, overriding the setting in the kernel settings file.

Use fail-safe graphics driver
The system will use VESA mode and won't try to use any video graphics drivers.

Disable IO-APIC
Disables using the IO APIC for interrupt routing, forcing the use of the legacy PIC instead.

Disable local APIC
Disables using the local APIC, also disables SMP.

Disable SMP
Disables all but one CPU core.

Don't call the BIOS
Stops the system from calling BIOS functions.

Disable APM
Disables Advanced Power Management hardware support, overriding the APM setting in the kernel settings file.

Disable ACPI
Disables Advanced Configuration and Power Interface hardware support, overriding the ACPI setting in the kernel settings file.

Blacklist entries
Allows to select system files that shall be ignored. Useful e.g. to disable drivers temporarily. See Troubleshooting below.

Select debug options Here you'll find several options that help with debugging or getting details for a bug report. Again, a short explanation for each option is displayed at the bottom.

Enable serial debug output
Turns on forwarding the syslog output to the serial interface (default: 115200, 8N1).

Enable on screen debug output
Display debug output on screen while the system is booting, instead of the normal boot logo.

Disable on screen paging
Disables paging when on screen debug output is enabled.

Enable debug syslog
Enables a special in-memory syslog buffer for this session that the boot loader will be able to access after rebooting.

Display current boot loader log
Displays the debug info the boot loader has logged (press Q to exit the log)

Add advanced debug option
Allows advanced debugging options to be entered directly.

If Enable debug syslog is activated, a warm reboot after a crash shows these additional options:

Save syslog from previous session during boot
Saves the syslog from the previous Haiku session to /var/log/previous_syslog when booting.

Display syslog from previous session
Displays the syslog from the previous Haiku session.

Save syslog from previous session
Saves the syslog from the previous Haiku session to disk. Currently only FAT32 volumes are supported.

Select screen resolution Lets you force a certain screen resolution and color depth.

index Troubleshooting

If Haiku refuses to boot on your hardware from the get-go, try out setting different options under Select safe mode options. Consider filing a bug report in any case.

On the other hand, if Haiku only suddenly acts up after you have installed some software, especially hardware drivers, you have several options to get Haiku bootable again so you can uninstall the offending package:

index Booting Haiku

After activating one or more options, you return to the main menu and continue booting, which presents you with this boot screen:

boot-screen.png

If everything works OK, one symbol after another quickly lights up.
The different symbols roughly correspond to these boot stages:

Atom Initializing modules.
Disk + magnifier Creating rootfs (/) and mounting devfs (/dev).
Plug-in card Initializing device manager.
Boot disk Mounting boot disk.
Chip Loading CPU specific modules.
Folder Final initialization of subsystems.
Rocket Launch_daemon has started the system.
