Hi all,First of all I hope I've come to the right place with my little bug (from what I've read this list seems to be preferred to the tracker?).
Anyway here it goes: I have two hard drives in my notebook, and tried installing grub (svn r1724) with it's root on the second one (/dev/sdb5 to be precise)
grub-install /dev/sdaEverything went smooth, however after rebooting I get dropped in rescue mode with this message: "unknown device fd1,5"
As I had a bit of free time I investigated where the fd1 might come from and it turned out that grub_root_device seems to contain a wrong value:
diff --git a/grub2/kern/i386/pc/init.c b/grub2/kern/i386/pc/init.c
index e47cbfd..01e8d7d 100644
--- a/grub2/kern/i386/pc/init.c

+ grub_env_set ("prefix", prefix);
+ grub_printf("0x%x, 0x%x, %s\n", grub_boot_drive, grub_root_drive, prefix ? prefix :
"<null>");
}

With this patch it prints "0x80, 0x1, (fd1,5)/boot/grub/"and I presume the 0x1 should actually be a 0x81, however I have no clue why it is wrong and as it seems to be initialized in startup.S I thought I'd leave it to the experts at this point.
After: set prefix=(hd1,5)/boot/grub set root=(hd1,5) insmod normal normal I end up in the menu and can boot my linux kernels just fine. Now for my second problem:If I try to chainload grub legacy on another partition it just hangs after printing "GRUB ". The command I used to do this was:
chainloader (hd0,5)+1 Chainloading my windows partition using: chainloader (hd0,1)+1 has a similar result, namely a blank screen with a blinking cursor.I would need some advice on how to debug this, but I guess the first interesting bit would be if this is broken for others as well, or just a peculiarity of my system.
