 Posted: Sat Aug 09, 2003 8:34 pm Post subject: Abit IT7 Grub Error 21 |
 |
|
I plug my Maxtor 80G hd on IT7 ide4(RAID-IDE), because I want to use ATA133 support, but i do not really use raid.
Using Gentoo 1.4 P4 livecd
partitions:
| Code: |
/dev/hde1 /boot ext2
/dev/hde3 / reiserfs
|
Grub
| Code: |
grub> root (hd0,0)
grub> setup --stage2=/boot/grub/stage2 (hd0)
grub> quit
|
grub.conf
| Code: | | kernel (hd0,0)/boot/bzImage root=/dev/ataraid/d0p1 |
but when i boot it up, i got grub.conf error 21

After GRUB says "error 21", do you get a GRUB prompt ?
If you do, try booting :
| Code: | grub> root (hd0,0)
grub> kernel /bzImage
grub> boot |
Then post your entire grub.conf because something is not right.
If this doesn't work, try booting from a GRUB floppy with the same commands. Then reinstall GRUB like this :
| Code: | # mount /boot
# cd /boot/grub
# rm *stage1_5 \\ this is a Highpoint BIOS workaround
# grub
grub> root (hd0,0)
grub> setup (hd0)
grub> quit |

I did not get prompt, it sux in Error 21.
| Code: |
default 0
timeout 10
splashimage=(hd0,0)/boot/grub/splash.xpm.gz
title=Gentoo 1.4
root(hd0,0)
kernel /bzImage root=/dev/ataraid/d0p3

Try putting a space between "root" and "(hd0,0)"
Also get rid of the reference to ataraid since you are not using RAID
| Code: | root (hd0,0)
kernel /bzImage root=/dev/hde3 |
|

Hmm ... this is strange
Do you have more than 1 harddrive in this machine ?
Did you load the ataraid and hptraid modules (or boot with doataraid) during installation ?
Maybe LILO will do a better job of seeing your harddrive correctly.
<edit> I think using "setup --stage2=/boot/grub/stage2 (hd0)" is what screwed-up GRUB </edit> |

Now i got following error message:
| Code: |
VFS: Canot open root device "" or 21:03
Please append a correct "root=" boot option
Kernel panic: VF: Unable to mount root fs on 21:03 |

| I think your motherboard has an HPT374 controller, which is not supported by the 2.4.20-gentoo-r5 kernel. I use ac-sources with my AT7-MAX2 motherboard. |
