9.8. Ramdisk Options

These options control how the storage of information in memory used to imitate disks (ramdisks) is done, including init ramdisks that hold information necessary at some stages of booting.

Location of initial ramdisk.

initrd= filename

Specify where the initial ramdisk for the kernel boot is located.

Load a kernel ramdisk from a floppy.

load_ramdisk= n

If n is set to 1, a ramdisk is loaded by the kernel at boot time from the floppy drive.

Do not use any initrd.

Do not load any initial ramdisk, even if it is configured in other options passed to the kernel.

Prompt for the list of ramdisks.

prompt_ramdisk=1

Prompt the user for the initial ramdisk before attempting to read it from the floppy drive.

Blocksize of the ramdisk.

ramdisk_blocksize= n

Tell the ramdisk driver how many bytes to use per block. The default size is 1,024.

Size of the ramdisk.

ramdisk_size= n

Specify the size of the initial ramdisk in kilobytes. The default size is 4,096 (4 MB). This option should be used instead of the older ramdisk command-line option.
