Re: what is the device.map used for ?
John Lumby wrote: Not a bug, not even a problem - just curious. I understand what the device.map is and how to specify it, but I have yet to come across something that uses it; When you boot and grub appears device.map has no sense. hd0 is the first hard disk given by the bios, hd1 is the second... and so. If you're under a unix/gnu/linux environment grub needs to know which linux device correspond to which grub device. If no device.map exists grub says: Trying to guess BIOS devices... this may take some time. You can edit the device.map but usually is created when installing the distro, anaconda, creates it. When you run grub there's an option to select another device.map file... you know it can be: my_own_device.map. When you run grub there's an option so that it does not read any device.map file. And there's the command (only inside the grub shell under a linux environment) you suspected which's name is device. device (hd0) /dev/hda maps the /dev/hda disk to (hd0) and it overrides what you already specified with the device.map or another device command. Usign the device command (or editing device.map) is useful for installing grub in pendrives,... because pendrives devices are not usually included on device.map files. adrian15 ___ Bug-grub mailing list Bug-grub@gnu.org http://lists.gnu.org/mailman/listinfo/bug-grub
Re: Gub 0.97 prevents boot from CD

I put in the disks (I have burned several) and each time the Grub Stage2 comes up and diverts control from the CD drive to the hard drive boot. What can I do to get my computer to boot from the CD drive first? 1) You can try to burn correctly the FC5 disk to a cdrom. To check if you've burned it correctly you can try just before trying to boot from it to try to boot it from qemu with: (/dev/cdrom is your cdrom device) qemu -boot d -cdrom /dev/cdrom If the cd does not boot in the qemu environment that means that you have not burned it correctly. 2) You can download http://adrian15.raulete.net/grub/tiki-download_file.php?fileId=58 this floppy image (To be burned into a floppy with dd after bunzip2ing) and try to boot your cdrom with BOOT FROM CDROM option. 3) You can check if your bios battery has finished its life and you have to replace it. (Once you've change the BOOT order have you power down the machine... rebooted... and checked and that it is still there?). adrian15 ___ Bug-grub mailing list Bug-grub@gnu.org http://lists.gnu.org/mailman/listinfo/bug-grub

[bug #16609] flash update ASUS bios, Grub wrote error mesage to mbr
Follow-up Comment #2, bug #16609 (project grub): If you try to reinstall Ubuntu you will see that I will boot again. That's my bet. But you can try to reinstall Grub on the Mbr only with Super Grub Disk Cdrom (if you only have a Linux) which is here: http://adrian15.raulete.net/grub/ Reinstall GRUB on the MBR Auto. Auto. I've heard that Grub to boot depends on some geometry parametres that are passed by the bios. The bios update (changing these geometry parametres) might have confused grub but if you reinstall it again it will take the right parametres and will work ok. adrian15 ___ Reply to this item at: http://savannah.gnu.org/bugs/?func=detailitemitem_id=16609 ___ Message sent via/by Savannah http://savannah.gnu.org/ ___ Bug-grub mailing list Bug-grub@gnu.org http://lists.gnu.org/mailman/listinfo/bug-grub
