Simple Menu System
For the isolinux bootloader you probably want to have a menu of choices for selecting what to boot. Tpday there are two versions of the simple menu system, the original text mode style and the new GUI style. The text mode style works on anything with a VGA card, which is almost every X86 box ever made. The GUI version works well with cards that have good VESA support.
Text Mode
Here is a typical example of a simple text-mode isolinux.cfg
file to configure a simple menu:
default menu.c32 prompt 0 menu title My Distro Installer timeout 600 f1 help.txt f2 version.txt label bls menu label Normal install menu default kernel vmlinuz append initrd=cpio.gz rdinit=/init label bad menu label Bad hardware install kernel vmlinuz append initrd=cpio2.gz badhardware rdinit=/init
global tags
The line with default menu.c32
activates the simple menu sytem. In this example the menu has two choices, bls and bad. As you can see, the global options are at the beginning of the file, and then there are a series of sections that begin with label
and end with a blank line. The timeout 600
sets a timer that counts down for 60 seconds. It says 600 since it measures time in tenths of seconds. Once that time expires, the menu entry that is the default is selected automatically. If no menu item has the menu default
then the first menu item is selected. The line with menu title My Distro Installer
will display My Distro Installer at the top of the generated text menu. The line f1 help.txt
will cause the contents of the file help.txt
to be displayed. The line f2 version.txt
will cause the contents of the file version.txt
to be displayed. The lines for f1 and f2 are optional. The line prompt 0
suppress the normal boot:
prompt.
Each menu entry starts with label name
where name is the name to type in to the boot:
prompt (which is still available if the users presses shift). The text to display on the menu is specified by the menu label
tag. The name of the kernel image to boot is specified by the kernel
tag. Remember, that name must be a valid DOS name fitting in the 8.3 limits and also the extensions can have special meanings. It is best to just use a short name with no extension and then you never have trouble. The final tag used in this example is the append
tag. The text specified after that tag will be added to the kernel image command line when booting the kernel. Normally you would at least specify your initramfs name with initrd=archive
and your initramfs boot script location with rdinit=/somescript
.
GUI mode
It is possible to show very nice looking graphics on most computers with the simple menu system. For technical people the graphics are not important, but for many end-users having a nice GUI display makes them feel your distribution is more professional.
