## password ['--md5'] passwd

# If used in the first section of a menu file, disable all interactive editing

# control (menu entry editor and command-line) and entries protected by the

# command 'lock'

# examples

#

# title Windows 95/98/NT/2000

# root (hd0,0)

# makeactive

# chainloader +1

#

# title Linux

# root (hd0,1)

# kernel /vmlinuz root=/dev/hda2 ro

#

#

# Put static boot stanzas before and/or after AUTOMAGIC KERNEL LIST

### BEGIN AUTOMAGIC KERNELS LIST

## lines between the AUTOMAGIC KERNELS LIST markers will be modified

## by the debian update-grub script except for the default options below

## DO NOT UNCOMMENT THEM, Just edit them to your needs

## ## Start Default Options ##

## default kernel options

## default kernel options for automagic boot options

## If you want special options for specific kernels use kopt_x_y_z

## where x.y.z is kernel version. Minor versions can be omitted.

## e.g. kopt=root=/dev/hda1 ro

## kopt_2_6_8=root=/dev/hdc1 ro

## kopt_2_6_8_2_686=root=/dev/hdc2 ro

# kopt=root=UUID=d72fd170-80fb-43da-b079-e51cd1a06a7c ro

## default grub root device

## e.g. groot=(hd0,0)

# groot=(hd0,2)

## should update-grub create alternative automagic boot options

## e.g. alternative=true

## alternative=false

# alternative=true

## should update-grub lock alternative automagic boot options

## e.g. lockalternative=true

## lockalternative=false

# lockalternative=false

## additional options to use with the default boot option, but not with the

## alternatives

## e.g. defoptions=vga=791 resume=/dev/hda5

# defoptions=quiet splash

## should update-grub lock old automagic boot options

## e.g. lockold=false

## lockold=true

# lockold=false

## altoption boot targets option

## multiple altoptions lines are allowed

## e.g. altoptions=(extra menu suffix) extra boot options

## altoptions=(single-user) single

# altoptions=(recovery mode) single

## controls how many kernels should be put into the menu.lst

## only counts the first occurence of a kernel, not the

## alternative kernel options

## e.g. howmany=all

## howmany=7

# howmany=all

## should update-grub create memtest86 boot option

## e.g. memtest86=true

## memtest86=false

# memtest86=true

## should update-grub adjust the value of the default booted system

## can be true or false

# updatedefaultentry=false

## ## End Default Options ##
