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.

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:
