Re: Grub 0.92 fails to recognise disks on FBSD5
Hi all, I'm fighting with the same problem and found that grub *does* recognize the disks if started with '--read-only'... That fits perfectly to the following paragraph found in the 5.0-RELEASE Errata: The geom(4)-based disk partitioning code in the kernel will not allow an open partition to be overwritten. This usually prevents the use of disklabel -B to update the boot blocks on a disk because the a partition overlaps the space where the boot blocks are stored. A suggested workaround is to boot from an alternate disk, a CDROM, or a fixit floppy. I can happily boot -current with grub - booting isn't the problem, installing it is the problem. And I installed grub from my 4.7-STABLE installation... (happy to have one :-) Grub seems to open disks/slices r/w and refuses to know them if that's not possible. I, personally, would say that's a bug of grub but that doesn't help here. It even doesn't help, if you run 5.0/-current on your base disk because you can't write the MBR anyway. My question to 'phk' is, if he (or anybody else) has or at least could imagine a solution for this problem. Nothing against 'booteasy', it does the job - but it looks ugly :-) And I can't imagine that the majority of FreeBSD-Users all have a bunch of disks in their systems - especially if I think of the giant sizes of HDs nowadays... -- Ciao/BSD - Matthias Matthias Schuendehuette msch [at] snafu.de, Berlin (Germany) Powered by FreeBSD 5.0-CURRENT To Unsubscribe: send mail to [EMAIL PROTECTED] with unsubscribe freebsd-questions in the body of the message

Rumours go that on Monday 03 February 2003 05:33, Jud spoke the following words: On Sun, 2 Feb 2003 14:02:17 + (GMT), William Palfreman [EMAIL PROTECTED] wrote: snip a lot That's what it says at one point in the docs. At another point it explains that no, the 1 isn't extra, and it uses what Chris has in its example FreeBSD section for the menu.lst file. (I used a similar config with GRUB, no problems.) i tried both ways to no avail. The info page actually says the (hd0,a) notation is a short-cut for (hd0,1,a), so they should be equivalent. I found in some mailing list archive some comments about the bios not providing the right hints... tho i think i can rule that out since i've been running grub for about three years on this machine both with FBSD4.5, 4.6 and several linuxes... Also, how new are you to FreeBSD? You sound quite new. not that new :) I came from Mandrake Linux, i've been using FBSD from the release of 4.5 until last september. Then i switched to gentoo linux, and when FBSD5 was released i thought to give it a shot. If I were you I would use FreeBSD 4.7 instead of 5.0 - I'd only use 5.0 if I were an OS developer or there was some feature on 5.0 that I desperately needed - like maybe I had a machine with more than 2 CPUs. I personally have no intention of going near 5.x until it is the -stable branch *and* everyone else has used it long enough to get the problems out. in general, i agree with your statement: if i had a machine depending on stability, i wouldn't switch :) my gateway still safely runs 4.7... but trying new things is kinda exiting, so... :) Dang! I missed that. GRUB may not recognize FreeBSD 5.0 disks - does anyone know for sure one way or the other? It looks like running FBSD5 is the only difference between my machine now and the machine when i ran 4.6 with grub... does someone know if and how i can determine this 100%? In any case, thanks all who have replied. If i find a solution, i'll make sure to post it, in the mean time, i'll be googling until evey piece of info on grub is on my pc :P regards, Chris To Unsubscribe: send mail to [EMAIL PROTECTED] with unsubscribe freebsd-questions in the body of the message

This is what the grub info file says: -- GRUB can load the kernel directly, either in ELF or a.out format. But this is not recommended, since FreeBSD's bootstrap interface sometimes changes heavily, so GRUB can't guarantee to pass kernel parameters correctly. Thus, we'd recommend loading the very flexible loader `/boot/loader' instead. See this example: grub root (hd0,a) grub kernel /boot/loader grub boot - Anyway, note that Grub is pointing to /boot/loader - you might as well use that instead of grub. It is a better bootloader IMO and its the default. It configures itself at run time, examining the disk to see what OSes are available. Use /stand/sysinstall to put it back on the MBR (if you have lost it), or if you want to use the slightly harder way, read the manpage for disklabel. I never use grub (or lilo) on any multiboot system when I have the FreeBSD loader available. Also, how new are you to FreeBSD? You sound quite new.

Two ideas, though you may want to wait to see if others more knowledgeable weigh in. Try the steps outlined in the manual regarding installing from a floppy disk. If that also runs into problems, try the device command to tell GRUB what hd0 is. Jud To Unsubscribe: send mail to [EMAIL PROTECTED] with unsubscribe freebsd-questions in the body of the message
