Thread: Adding "reserve=" to grub2

i've installed natty on fresh install of lucid try out.

have weird , wonderful laptop bios bug hardware memory addressing , need add "reserve=0xffb00000,0x100000" boot parameter, see link:
http://www.fitzenreiter.de/averatec/index-e.htm

author gives instructions on how , put these things menu.lst, grub2 things different (and i'm bit thick!)

please point me in right direction put them grub2 kernels , future updates pick parameter up?

have no sound natty either , don't know start looking, i'll post in different thread...

thanks,

this create custom entry grub.

sudo gedit /etc/grub.d/40_custom

file should looks like:

#!/bin/sh
exec tail -n +3 $0
# file provides easy way add custom menu entries. type the
# menu entries want add after comment. careful not change
# 'exec tail' line above.

add new custom entry file, example of grub2 menu entry:

menuentry 'ubuntu, con linux 2.6.38-8-generic' --class ubuntu --class gnu-linux --class gnu --class os {
recordfail
set gfxpayload=$linux_gfx_mode
insmod part_msdos
insmod ext2
set root='(/dev/sda,msdos1)'
search --no-floppy --fs-uuid --set=root f1139728-31c0-4033-b3af-78eaa5694eef
linux /boot/vmlinuz-2.6.38-8-generic root=uuid=f1139728-31c0-4033-b3af-78eaa5694eef ro quiet splash vt.handoff=7
initrd /boot/initrd.img-2.6.38-8-generic
}

the final file should like:

#!/bin/sh
exec tail -n +3 $0
# file provides easy way add custom menu entries. type the
# menu entries want add after comment. careful not change
# 'exec tail' line above.
menuentry 'ubuntu, con linux 2.6.38-8-generic' --class ubuntu --class gnu-linux --class gnu --class os {
recordfail
set gfxpayload=$linux_gfx_mode
insmod part_msdos
insmod ext2
set root='(/dev/sda,msdos1)'
search --no-floppy --fs-uuid --set=root f1139728-31c0-4033-b3af-78eaa5694eef
linux /boot/vmlinuz-2.6.38-8-generic root=uuid=f1139728-31c0-4033-b3af-78eaa5694eef ro quiet splash vt.handoff=7
initrd /boot/initrd.img-2.6.38-8-generic
}

then sudo update-grub2

guess "reserve" must in line "quiet" , "splash".

can copy default entries /boot/grub/grub.cfg paste in 40_custom, edit entrie new parameter , update grub.

let me know if works.
