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 , 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

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.

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

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.

Grub 0.92 fails to recognise disks on FBSD5
Hi all, i'm experiencing problems with the installation of the GRUB bootloader. I have installed the port (grub version 0.92) and created the /boot/grub directory with the files from /usr/local/share/grub/i381-freebsd. Next I created a menu.lst file in /boot/grub and thought to install GRUB in the mbr, so I launch the grub shell. My fbsd install is on ad0s2 with / on partition a. If i am correct that should be (hd0,1,a) for grub, right? well this is what i get: grub> root (hd0,1,a) Error 21: Selected disk does not exist I looked up the error in the manual and it says: "This error is returned if the device part of a device- or full filename refers to a disk or BIOS device that is not present or not recognized by the BIOS in the system." which doesn't help me much i'm afraid... dmesg shows my disk as follows: ad0: 39266MB [79780/16/63] at ata0-master UDMA100 does anyone have a clue what's going on here?
