I have looked at the GNU GRUB Manual 1.99 at [URL] but I cannot find an explanation of what the kernel entry / command in the grub.conf file means. I get what's the meaning of that entry but where is described what it actually is and what are proper.
I suppose this entry / command was actual in GRUB Legacy, but I cannot find where it is described...
I want to avoid kernel id in Grub entry. I have searched before and one poster (can't find it again) posted a very simple Fedora Grub entry that just pointed to Fedoara's menu.lst. which worked.
For Suse I use:
title openSUSE 11.1 (on /dev/sda7) by symlinks
root (hd0,6)
kernel /boot/vmlinuz root=/dev/sda7 splash=silent showopts vga=0x31a
initrd /boot/initrd
savedefault
boot
I nave tried:
title Fedora
root (hd0,4)
rootnoverify (hd0,4)
chainloader +1
Where Fedora is on sda5 but, doesn't work for some reason.
I have manually added an entry for Ubuntu in my grub menu, using Yast. But every time the kernel is updated, this entry disappears. On the other hand, the one for Windows, that was added during OpenSuse's installation, is still there. So how can I keep this entry for Ubuntu ?
Edit : when I save the menu configuration in Yast, I get the following message :
Code:

I would like - instead to USB-key that is always not to be found, to somehow "move" the clonezilla (on a USB stick). What I have tried to is to make a separate partition to install this on, copied all the files on the USB -key to that partition, and then make a new entry in GRUB via yast. Then I point to the new wmlinus and initramfs. I would have been much surprised if something link this was working after first shot. But it was also not working after the 80. shot.

The *.dbf files (DBase III Plus files) have a header (metadata) and follow with n fixed records. I'd like to make a directory entry (like a symbolic link) that point to the fixed record area into a .dbf file. Is it possible in linux? The request is motivated by access a .dbf file from a Firebird SQL Database using CREATE TABLE EXTERNAL FILE '/tmp/mydbf.dbf' ( ... ); but this command only works on fixed records.

My brother is working for a company that is making various types of embedded software. He's been trying to install Micro Core Linux on a device, and it worked after some manual kernel patching & configuring. The issue is this; he need to install this system on hundreds of similar devices. Is there a way of making the configured kernel into a bzImage, so that the kernel can be compiled on the other systems without any tweaking?
View 5 Replies View Relatedwhat kernel file holds the functions for the hardware configuration. I'm interested in finding the hardware timer of the linux and the DMA configuration file. I assume there is a single file that holds configuration data for the platform.This probably is executed before the kernel is started. As is see it this must be some hardware abstraction layer file because the actual kernel code is not platform dependent.
View 1 Replies View RelatedI just installed archlinux to try it out and need to add the entry to Grub.
I formated the hard drive with the a root partition for arch of 42Gb and ubuntu can see it perfeclty.
When I was installing arch I made a mistake and installed grub again, overwriting my previous grub with my ubuntu and windows entries.
So I fixed and got my working grub back with SuperGrubDisk, but now I want to add the ARCHLINUX entry to Grub and dont know how. I have added the previous entries from the grub that ARCH installed and moved the initrd and vmlinuz files to the /boot directory on ubuntu, but it doesnt work. I did a similar thing with Acronis True Image rescue cds(to avoid having to insert the cd in order to use it) and it worked like a charm, but I am lost in this one.
Here are my partitions, sdb is the one where all my partitions and files are (sdb5 is where ARCH is), the other 2 are backups:

I'm hoping someone can help me. I upgraded my server from Lenny to Squeeze this afternoon following the release notes at http://www.debian.org I had no issues and everything is still running. I then installed Sqeeze via the Net Install disc into a virtual machine for some testing. Once the install was complete I found that apt was not working. It turned out the sources file was blank. I manually added the official repos and did an update. There were no new packages for installation.
Now, after a reboot, I get the Grub error:
error: ELF header smaller than expected
Entering rescue mode...

I have no idea why this happened because I've not changed grub, just played around with apt. Has anybody any idea why apt had a blank sources file and grub is now failing?
I'm playing with Fedora 12 and can't get GRUB to work. To boot, I've been using GRUB4DOS. While that works fine, I'd like to figure out what's wrong with regular GRUB 0.97. After the initial installation, GRUB came up on reboot, but it was broken -- it couldn't read the config file apparently, and no commands would work correctly. So I attempted to reinstall grub via the grub prompt. No matter what I do, or which hard disk I install GRUB on, I get "Error 18". I tried using the "grub-install" command as well as the prompt, and that did the same thing.
My system here is an ASUS M4A785TD-M EVO mo/bo. I've got four hard drives. Two 1TB SATA drives and a couple of PATA drives (300 and 500GB) on a Si608 controller card. Using the BIOS "BBS" boot menu, I can boot NTLDR and BOOTMGR off active partitions on any of the drives (with proper Boot.ini modifications to handle the change in drive order). GRUB4DOS works as well, and will boot Fedora 12 correctly off any of them (with proper menu.lst ministrations). But GRUB 0.97 that comes with Fedora just refuses to do anything other than say "Error 18".
I have to add a new interrupt framework to the kernel (INT 81h). To add the interface descriptor to INT 81h I have to write to the IDT entry 81h. There are some functions of the kernel that can do this task but they can not be used in a module. So I will now do a patch to the kernel and don't know where to start.
Where is INT 80h interface descriptor written to the IDT? - So I could write it maybe the same way in the same function. Which GTD entry is used to write to the IDT (1, 2, 3 or ...) ? - So I can do some debugging.
When I only change a driver file manually, for example /newkernel/linux-source-.6.32/drivers/gpu/drm/i915_drv.h, do I need to run "make config" or similar like "make menuconfig" or can I just skip? I mean these steps:
1.) apt-get install linux-source-2.6.32
2.) mkdir ~/newkernel/
3.) cp /usr/src/linux-source-2.6.32.tar.bz2 ~/newkernel/
4.) cd /newkernel/
5.) tar xjf linux-source-2.6.32.tar.bz2
6.) cd linux-source-2.6.32
7.) cp /boot/config-$(uname -r) ./.config yes "" | make oldconfig
8.) change the driver file /newkernel/linux-source-2.6.32/drivers/gpu/drm/i915_drv.h manually
8.) make-kpkg clean
9.) make-kpkg --rootcmd fakeroot --initrd --revision=custom.001 kernel_image kernel_headers
10.) dpkg -i *.deb
Is this way OK or do I miss something?
I have a pc where there was redhat installed, and I decided to put ubuntu in dual boot.The installation went ok, but now I can't log in with redhat anymore. RH was installed on a RAID partition, and I installed ubuntu on an additional HD.
Now I have two problems:
a) I cannot boot red hat, since there is no such entry in the grub
b) this machine had several users, that now cannot access it remotely anymore.
Below you can find the output of fdisk -l and the grub.cfg files, the old red hat one, and the new one created by ubuntu. Not that in any case I cannot reinstall redhat, since there are other people using the machine.

I was cleaning old kernels from Grub menu, all sorted except for a vista entry that i could not delete. Ran this line which I found,"sudo chmod -x /etc/grub.d/30_os-prober", to remove unwanted entries, now only the linux entry left in Grub menu, windows 7 entry gone. The vista entry was from an old install which is not there anymore. Running 10.10 at the moment which is dualbooted with win7.

View 3 Replies View RelatedI have a Dell Latitude E6410 which I can boot from an Iomega external hard drive when I want to run Linux on it. It is a work issued Windows XP laptop and when I travel, I am more comfortable with Linux, so I created a dual boot option without touching their hardware. The external hard drive plugs in to the USB ports and the BIOS picks it up as the primary boot media, although the internal drive is still present. (That is the desired outcome).The problem is that the system periodically locks up solid and only a forced power off will get it to respond. The system seems to go into a kernel panic and fails to write anything before dying. The system completely locks up and stops responding to mouse and keyboard. It also seems to drop off the network. When I look at the logs after restarting, nothing at all shows up related to a kernel panic or anything else. To further complicate the diagnosis, on the reboots, sometimes the boot process locks up at "Starting GDM3", sometimes it doesn't, and wont for several attempts but eventually will boot to gnome. Some times it runs fine for a few hours, sometimes for only a few minutes. Can anyone recommend a way to diagnose this?I am trying to run Debian 6.0 32-bit with the defaults.

I have installed ubuntu 9.10 and everything was working fine. Just a minutes ago a window popped up telling me that a complete update couldn't be completed, and asked me to go on with a partial update. I did it and then a window popped up (I think it was debconf running) asking me if I wanted to delete phpmyadmin database configuration or if I wanted to keep it... seemed like the updater was removing quite a bunch of packages!
After that I was presented with a long list of packages to be removed (among them apache2, php5, linux headers, etc.) I thought it was going to remove them in order to reinstall them latter, so I let it go) but now there's no ubuntu entry in the grub menu, so I had to boot with windows! Right now I'm downloading ubuntu 9.10 livecd to give it a try...
My problem is this, I decided to try Pardus since I had the disk space available and learned that it never created a entry for Ubuntu 9.10 64-Bit. I have tried many different boot options and have only gotten it to show the first black and white bootsplash but never can continue to boot. Is there a option I am forgetting to add via Pardus's GRUB editor or is it something else?
