add "boot from cd" to grub

[valemon]

Can I add to grub a boot from cd option in order not to change it from BIOS from time time?

[devils casper]

its possible to add this option in GRUB but it creates problems in a few machines coz GRUB's functions depends on BIOS too.
first of all, set first boot device to CD Drive in BIOS. dont insert any CD in CD Drive and power on machine. does it ask for CD or transfer control to Second Boot device (Harddisk) ?

[valemon]

it doesn't ask for cd andboots from the second boot device

[devils casper]

in that case, you dont need to add an entry for CD in GRUB. insert any CD, Machine will check if its bootable or not. if its not, machine will pass control to Second Boot Device and if CD is bootable, machine will boot from it.

anyways, you can add this code in menu.lst

title Boot from CD
chainloader (hd2)+1

add this code in /boot/grub/device.map file

(hd2)  /dev/hdc

Just did it, rebooted and this is the output:

chainloader (hd2)+1
error 21: Selected disk does not exist
press any key to continue...

did you add entry in device.map file?
post the contents of /etc/fstab file.

[valemon]

Yes, I added the line.
device.map:

/dev/hda5 / ext3 acl,user_xattr 1 1
/dev/hda6 /home ext3 acl,user_xattr 1 2
/dev/hda1 /windows/C ntfs ro,users,gid=users,umask=0002,nls=utf8 0 0
/dev/hda2 swap swap defaults 0 0
proc /proc proc defaults 0 0
sysfs /sys sysfs noauto 0 0
debugfs /sys/kernel/debug debugfs noauto 0 0
usbfs /proc/bus/usb usbfs noauto 0 0
devpts /dev/pts devpts mode=0620,gid=5 0 0
/dev/fd0 /media/floppy auto noauto,user,sync 0 0

[devils casper]

post the contents of device.map file too.

less /boot/grub/device.map

[valemon]

(fd0) /dev/fd0
(hd0) /dev/hda
(hd2) /dev/hdc

That's all in there

[devils casper]
