Kernel parameters
This window lets you specify one or more parameters of the Linux kernel. They will be automatically
applied when the bootable media starts.
These parameters are typically used when experiencing problems while working with the bootable
media. Normally, you can leave this field empty.
You also can specify any of these parameters by pressing F11 while in the boot menu.
Parameters
When specifying multiple parameters, separate them with spaces.
acpi=off
Disables Advanced Configuration and Power Interface (ACPI). You may want to use this
parameter when experiencing problems with a particular hardware configuration.
noapic
Disables Advanced Programmable Interrupt Controller (APIC). You may want to use this
parameter when experiencing problems with a particular hardware configuration.
vga=ask
Prompts for the video mode to be used by the bootable media's graphical user interface.
Without the vga parameter, the video mode is detected automatically.
vga=mode_number
Specifies the video mode to be used by the bootable media's graphical user interface. The mode
number is given by mode_number in the hexadecimal format—for example: vga=0x318
Screen resolution and the number of colors corresponding to a mode number may be different
on different machines. We recommend using the vga=ask parameter first to choose a value for
mode_number.
quiet
Disables displaying of startup messages when the Linux kernel is loading, and starts the
management console after the kernel is loaded.
This parameter is implicitly specified when creating the bootable media, but you can remove this
parameter while in the boot menu.
Without this parameter, all startup messages will be displayed, followed by a command prompt.
To start the management console from the command prompt, run the command: /bin/product
nousb
Disables loading of the USB (Universal Serial Bus) subsystem.
nousb2
Disables USB 2.0 support. USB 1.1 devices still work with this parameter. This parameter allows
you to use some USB drives in the USB 1.1 mode if they do not work in the USB 2.0 mode.
nodma
Disables direct memory access (DMA) for all IDE hard disk drives. Prevents the kernel from
freezing on some hardware.
