21.1. Description

Additional parameters that can be applied prior to booting Linux kernel

Description

The following parameters can be used to load Linux kernel in a special mode:

• acpi=off

Disables ACPI

and may help with a particular hardware configuration.

• noapic

Disables APIC (Advanced Programmable Interrupt Controller) and may help with a particular

hardware configuration.

• nousb

Disables loading of USB modules.

• nousb2

Disables USB 2.0 support. USB 1.1 devices still work with this option. This option allows using some

USB drives in USB 1.1 mode, if they do not work in USB 2.0 mode.

• quiet

This parameter is enabled by default and the startup messages are not displayed. Deleting it will

result in the startup messages being displayed as the Linux kernel is loaded and the command being

offered prior to running the Acronis program.

• nodma

Disables DMA for all IDE disk drives. Prevents kernel from freezing on some hardware.

• nofw

Disables FireWire (IEEE1394) support.

• nopcmcia

Disables PCMCIA hardware detection.

• nomouse

Disables mouse support.

• [module name]=off

Disables the module (e.g. sata_sis=off).

• pci=bios
