+Graphical boot screen
+=====================
+
+ syslinux/isolinux support a graphical boot screen using VESA BIOS
+ extensions. (Note that this is different from the graphics support that
+ syslinux comes with).
+
+ To use it you have to prepare a special boot logo file and put a line like
+ this into syslinux.cfg/isolinux.cfg:
+
+ gfxboot foo
+
+ The tools to create 'foo' from the above example are in the gfxboot
+ package. Please _do_ have a look at its documentation before you begin.
+
+ Note that you cannot use comboot images and graphics at the same time as
+ the memory used overlaps the comboot loading area.
+
+ If you encouter problems with the graphics code, hold down SHIFT while
+ syslinux starts. This will put it into 'failsafe' mode that lets you
+ interactively skip critical parts (like monitor detection).
+
+
+
+Spread boot images over several floppy disks (syslinux)
+=======================================================
+
+ You can prepare boot disks with a file system that spans several disks.
+ The 'mkbootdisk' script from the openSUSE project can create a suitable
+ file system.
+
+ syslinux will ask you for disk changes if necessary. To enable this
+ feature, use
+
+ disksize <size_of_single_disk_in_sectors>
+
+ Note that every individual disk must have at least a valid FAT boot
+ sector. syslinux will use the serial number stored there to verify that
+ the correct disk has been inserted (its last hex digit is the zero based
+ disk number).
