Welcome to the 09Slackware07 Linux custom bootdisk!
|
|||
|
|
|
|||
|
|
By default, this disk boots a root Linux partition on $ROOT_DEVICE when you
|
|||
|
|
hit ENTER. If you'd like to boot some other partition, use a command like
|
|||
|
|
this on the prompt below:
|
|||
|
|
|
|||
|
|
mount root=/dev/sda1 ro
|
|||
|
|
|
|||
|
|
Where "/dev/sda1" is the partition you want to boot, and "ro" specifies that
|
|||
|
|
the partition should be initially mounted as read-only. If you wish to mount
|
|||
|
|
the partition read-write, use "rw" instead. To set the video console mode,
|
|||
|
|
use the vga= parameter (press F1 to see a table). You may also add any other
|
|||
|
|
kernel parameters you might need depending on your hardware, and which
|
|||
|
|
drivers are included in your kernel.

STANDARD MODES:
|
|||
|
|
To make the kernel prompt for standard video modes use: vga=ask
|
|||
|
|
|
|||
|
|
FRAMEBUFFER MODES:
|
|||
|
|
To get the kernel to start in VESA framebuffer mode, you need to pass it
|
|||
|
|
a vga= init string on the "boot:" prompt. Here's a table:

Welcome to the Slackware Linux custom LILO bootdisk!
|
|||
|
|
|
|||
|
|
By default, this disk boots a root Linux partition on $ROOT_DEVICE when
|
|||
|
|
you hit ENTER. If you'd like to boot some other partition, use a command
|
|||
|
|
like this on the LILO prompt below:
|
|||
|
|
|
|||
|
|
mount root=/dev/sda1 ro
|
|||
|
|
|
|||
|
|
Where "/dev/sda1" is the partition you want to boot, and "ro" specifies that
|
|||
|
|
the partition should be initially mounted as read-only. If you which to mount
|
|||
|
|
the partition read-write, use "rw" instead. You may also add any other kernel
|
|||
|
|
parameters you might need depending on your hardware, and which drivers are
|
|||
|
|
included in your kernel.
