I'm looking to edit my grub.cfg file to add the "pci=routeirq" code to the kernel line so I can configure my modem in Ubuntu. I'm happy with assigning a temporary permission to myself over the root file so I don't accidentally alter it later.

I have a file which a number at the end of each line. I need to change this number in the file to be correct, i.e. each time the number is 9 it needs to be 1, each time it is 233 it needs to be 2, etc... There is no pattern to the numbers currently in the list other than the same number appears only in a single line/group of lines, not throughout the file, but the replacements need to be sequential (but can be repeated an arbitrary number of times).

View 3 Replies View RelatedThe ability to manually boot using the Grub command-line constitutes a big security risk in Linux, IMO.Any OS can be booted in this manner from a PXE-LAN, USB, or CD/DVD drive, circumventing BIOS-imposed boot restrictions. (Once a foreign OS is booted, of course, it can be used to access any part of an unencrypted hard drive.) Placing passwords or locking menu items (in the Grub configuration files) does not prevent a user from booting manually using commands entered at the grub command-line.
As it stands now, when presented with the Grub menu (or after bringing up a hidden Grub menu with the "ESC" key), a user only needs to hit "c" to enter the Grub command-line mode to facilitate any type of bootup whatsoever. (They can then enter manually the Grub commands to boot an OS on any device.) This is extremely insecure and allows any passerby to boot the computer with a few keystrokes and a bootable USB drive. How do I configure Grub so that it will require a password in order to enter the command-line mode (and thereby restrict boot options to the menu, which can then be password protected/locked) ?
I have recently installed Ubuntu Karmic on my laptop, which also has Windows 7. It now has GRUB, and I have been able to modify some settings via the GRUB command line. However, these changes are not permanent; they are reset the next time I load GRUB. I have seen many people trying to configure GRUB who have been pointed towards /boot/grub/menu.lst. I expect it would) I went to edit that file... and discovered that it did not exist. I am certain that I am using GRUB, not some other bootloader. Is there another possible way to configure GRUB, or somewhere else I might look for this file?

View 4 Replies View RelatedI updated the kernel to 2.6.35.10-74.fc14.x86_64 and had to reinstall and rebuild the kernel module for my ATi driver as usual, so I edited the kernel arguments at the grub splash screen so that I could boot into single user mode and install the driver (i.e appending the relevant line with '1'). The interesting thing is, the system booted directly into single user mode as root when the system started up. No password was required.
