GRUB boot loader "kernel" options??

registering · 08-16-2005, 07:19 PM

Hello,
How do I pass kernel parameters (read: init arguments) like "single" or "emergency" to GRUB prior to it booting a particular kernel img? I do not want to modify /boot/grub/grub.conf, I want to know how to do it every time the system boots. For example, in Red Hat EL v4.0, you click 'e', then scroll to 'kernel' then click 'e', add your parameters, then 'b' to boot. I can't find any keystrokes that let me do this in Mandriva 10.2 or anything in their documentation on how to do this.
Thanks!

Try pressing ESC.

Pressing ESC takes me to the boot prompt, however it does not give me the default kernel parameters used to boot so I can modify them accordingly and continue. Is there a way to have those defaults displayed after pressing ESC? The only "help" there, was to hit TAB, at which time it merely gave me a list of those bootable options as defined in /boot/grub/grub.conf. The "help" mentioned no other possibilities.

You have LILO as your bootloader, not Grub. Use urpmi to install grub and then you'll be able to amend the kernel boot line at startup. LILO is the Mandriva default bootloader. If you don't specifically ask for Grub when you install Mandriva you must do it manually.

Thanks, I didn't know that! Too late now as I've wiped it for RHELv.4.0, but I'll definitely keep that in mind for when I put MDV2006 on my box next month. I don't know why they still use LILO though, that surprises me.
