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:
