Well, if it is switching video modes, it probably needs to do so. I wouldn't call that a bug. If the blanking is your monitor blacking out while it resyncs, that's also an expected behaviour. Just checking the obvious, but does your grub.conf file have two splashimage commands?

Understanding what's going on is fine, and good. I don't discount the importance of it. The solution for a duff MBR is to rewrite the MBR with what you want. You don't uninstall an unwanted bootloader, you put another boot record (that you want) over the top. -- [EMAIL PROTECTED] ~]$ uname -r 2.6.25.9-76.fc9.i686 Don't send private replies to my address, the mailbox is ignored.

I, in fact, saved those instructions and went back to the manual to make sure I thoroughly understood what I was doing. I will use them in the morning. If you remember, except for the double splashimage, my system is booting as it should. Rather than simply getting things to work, the challenge to me over the last couple of days has been to fully understand what has been happening. I have managed to dig into the workings of the mbr, grub stages, video modes much deeper than if I had simply left things as a booting problem to fix. As I have said, I have climbed the grub learning curve in the past. This time I wanted to take an active role in actually undoing something or fixing something. > grub > root (hd.

Can't comment on grub2 yet as I've seen it only once or twice, I think, and it's a different code base.

William Case wrote: Hi Mikkel; If I remember correctly from the first thread, you would get a brief flash on the screen with Fedora at the top of the screen, a short pause, and then the proper splash screen with Fedora on the bottom. This is a good indication that ether the video card or the monitor are changing modes to properly display the splash screen. I would suspect that it is the monitor changing modes to match the video output. Yes. And that was where I was going to leave. There was a suggestion on the list that I should file a bug against grub. I was about to do that this morning and thought that I should check the first 512 bytes of each disk just to be sure. I checked and low and behold I found GRUB listed in the first block (mbr ??) of both disks. So I thought I should chase that down before I filed an inappropriate bug report. This should not be a problem. Because the part of Grub on the MBR does not display anything - it just loads the next part of Grub. The MBR on the second hard disk would not be used unless it was chained to by another copy of Grub, or if you tell the BIOS to boot from the second hard drive instead of the first. (Or if you swap the drives, or remove the first drive...) Didn't the problem go away when you turned off the splash screen, and ran Grub in the text mode? Yes, it does. Which makes the problem a Fedora grub problem, not just a grub problem -- I would think. Unless Fedora modified Grub to use splash images, it would be a Grub problem.

Here it is; About four weeks ago my commercial boot loader (BootMagic) was blown away by the WindowsXP sp3 download and install. Fine and good: that didn't surprise me -- it was an old version of BootMagic kept out of stubbornness. I had paid for it before I started using Linux so I was going to use it. I had climbed the grub learning curve a couple of years ago, so I am fairly confident about using the grub shell or grub-install. When BootMagic was blown away, I just installed grub. During a first attempt at a grub install I had an ooops! So I just re-installed grub and everything seemed fine. The intent was to install grub on /dev/sda dual booting to sdb /boot. (BIOS loads in the natural hd0, hd1 order.) Because it was an oops (typo) and not a confusion, I didn't pay attention to the mistake, so now a month later I have forgotten exactly what I did wrong. Besides I thought I had recovered. About a week ago (I don't re-boot very often), I noticed the Fedora grub splash screen appear for 1/2 second or less, then go blank and pause for a second or two. Then a new splash screen appeared and everything progressed fine from there. This occurs definitely during the grub stage of bootup. I didn't do anything then because I was going to fresh install Fedora 9 with a new grub. Which I have done. But the double splash screen still appears. To add to the confusion, I installed a new motherboard with a new and different video chip three months ago. Since I don't boot often, I could have not noticed the double splashimage for some time. This would support the changing video mode suggestion. -- Regards Bill; Fedora 9, Gnome 2.22.2 Evo.2.22.2, Emacs 22.2.1 -- fedora-list mailing list fedora-list@redhat.com To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list

This is a good indication that ether the video card or the monitor are changing modes to properly display the splash screen.

| From: William Case <[EMAIL PROTECTED]> | 1) stage1 is one line that is installed on the mbr within the 64 bytes | or 512 bits that is reserved on the disk for booting purposes. Boot records are 512 bytes. The code must fit into about 440 bytes of this. The Master Boot Record (MBR) is the first block on the hard drive. http://en.wikipedia.org/wiki/Mbr is worth a read. Each partition also has a boot record. The good-old-fashioned code in the MBR looked for the first bootable primary partition and booted the boot record from that. "bootable" is an attribute of a partition table entry that you can set by fdisk(8) "a" command, for example. This was the conventional way for switching which OS to boot. Note: this does not allow for booting from "logical" partitions. The extended partition's can be used -- I've sometimes put LILO or GRUB's boot record there.

Stage1 has the sole function of directing grub to stage1_5 or the grub loader which is stage2. Stage1 is not grub but only a short binary that directs the harddisk to read the next stage. The grub program is in stage2. 2) stage1_5 (stage 1.5) is a file that can reside on the first track next to the mbr. stage1_5 is used when the instructions of where to boot from are more complex than can be handled by the small mbr. In that case stage1 directs grub (actually the controller of the harddisk) to read stage1_5 which then directs grub to read stage2 wherever stage2 happens to be installed. 3) stage2 is a the binary executable that contains the actual boot loading instructions. Stage2 gets some of the details for how and what to load from the grub.conf file. It is common on a dual boot system, to read the mbr of the first harddisk (first, second etc. is established by the BIOS setup) and then be directed to the /boot directory of the second harddisk in order to read stage2. Stage2 reads the information contained in the /boot/grub/grub.conf | menu.lst and proceeds to boot. When booting, if the hiddenmenu has been commented out, grub shows one and only one splashscreen with a menu. For a dual boot with Windows as an option, the menu gives the user the choice of the latest Linux kernel, the next to latest kernel and/or to chainload Windows (Other). Whichever is selected (or the default), grub boots directly into that Operating System. My /boot/grub/grub.conf is as follows: # boot=/dev/sda default=0 timeout=5 splashimage=(hd1,4)/grub/splash.xpm.gz ## hiddenmenu title Fedora (2.6.25.6-55.fc9.x86_64) root (hd1,4) kernel /vmlinuz-2.6.25.6-55.fc9.x86_64 ro root=UUID=884ffe2a-42ff-4835-bf57-b80bc45c3baa rhgb quiet initrd /initrd-2.6.25.6-55.fc9.x86_64.img title Fedora (2.6.25-14.fc9.x86_64) root (hd1,4) kernel /vmlinuz-2.6.25-14.fc9.x86_64 ro root=UUID=884ffe2a-42ff-4835-bf57-b80bc45c3baa rhgb quiet initrd /initrd-2.6.25-14.fc9.x86_64.img title WindowsXP sp3 rootnoverify (hd0,0) chainloader +1 There is no reason why I should be having this menu flash once and disappear, pause, then load so that I can make an OS choice. As has been suggested here by others, it looks like one stage2 has become entangled with a second stage2. I cannot find a second stage2. I have used 'locate', 'find', and 'grub> find' to search both disks. In fact, root]# grub> find /boot/grub/grub.conf returns 'file not found' error 15. I have not yet used grub> find from the rescue disk command line. I am about to try that next to see what it can tell me. And, in fact, in the past, if I let anaconda automagically install the grub setup, it gave me exactly that: stage1 on the sda mbr and stage2 in /boot of sdb. It should have done that when I installed F9, yet somehow grub remained entangled with an extra stage2. -- Regards Bill; Fedora 9, Gnome 2.22.2 Evo.2.22.2, Emacs 22.2.1 -- fedora-list mailing list fedora-list@redhat.com To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list

Sorry to keep at this, but I am stumped. I don't want to risk prematurely re-installing grub without discovering the cause of the baton passing. Who knows what I might mess up.

The short splashscreen is normal if the timeout parameter is not set or is set to a small value. Could you have a /boot on /dev/sda that is chaining to one on /dev/sdb? With a stanza in grub.conf like title Other rootnoverify (hd1) chainloader +1 or title Other rootnoverify (hd1,0) chainloader +1 It is a clean way of handling multiple linux operating systems and letting each handle its own boot and grub configuration.

About four weeks ago my commercial boot loader was blown away by the so, this is what is calling grub on /dev/sdb. you do not need it and may be better off if you just use grub on /dev/sda to select oos or fedora. unless you have something that grub can not load. if not, you can/should either follow tim's grub install using 'grub ' or use single command as you posted. either way, you can/should change install to /dev/sda and make changes to 'grub.conf' and include oos. m2c. ymmv. -- tc,hago. g . in a free world without fences, who needs gates. -- fedora-list mailing list fedora-list@redhat.com To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list

Shouldn't really be necessary to do anything other than rewrite the MBR (you could that by backing it up with dd before any changes, then restoring it again the same way). Running fixmbr should only affect the drive that Windows is on. So the only thing lost will be the MBR, the rest of GRUB will be unchanged (stage2 will still be where it was before). When I've restored GRUB, I've done it this way: Get into a GRUB shell: Type the "grub" command.

Tell GRUB where to write the boot record to (the MBR the BIOS will boot): Type a "setup (hd0)" command line (first drive MBR). Make GRUB actually do it: Type the "quit" command.

But it isn't. In any case, I have spent time with grub in the past and generally comfortable using it. I asked here as a double check because what I am planning will wipe out my boot loader for both of my systems temporarily and I wanted to make sure that I can be up and running as smoothly as possible. -- Regards Bill; Fedora 9, Gnome 2.22.2 Evo.2.22.2, Emacs 22.2.1 -- fedora-list mailing list fedora-list@redhat.com To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list

Double checking grub-install ??
Hi; I have to run fixmbr on my WindowsXP harddisk (sda). I assume this use of fixmbr will blow away my grub. So after running fixmbr I will go to my Fedora rescue disk and do: grub-install --root-directory=/boot /dev/sdb That is; I want grub stage1 on the mbr of sda while I want stage2 on sdb /boot. I am looking for confirmation that this is a correct strategy and the proper use of the grub-install command. -- Regards Bill; Fedora 9, Gnome 2.22.2 Evo.2.22.2, Emacs 22.2.1 -- fedora-list mailing list fedora-list@redhat.com To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list
