 Posted: Sat Apr 22, 2006 10:46 pm Post subject: Reboot returns to bios with no operating system error |
 |
|
I am running 2.6.16-gentoo-r3 on a Tyan S2466 with 2 2600+ Athlon MP chips, and running off a 3ware 9500S8.
The system runs fine until I try to reboot it, at which point it returns to the bios bootup as if it did not find a hard drive, and continues to check the next boot device on the list. When this fails (PXE) it gives me a no operating system error.
I've tried changing the kernel settings to disable ACPI, APM, and I tried disabling ACPI in bios. I don't know what else to try. |

xmltok,
Welcome to Gentoo.
Your symptoms suggest that the BIOS cannot find a disk with a bootloader installed.
Which bootloader do you use and how did you install it onto your MBR ?

| I installed grub with grub-install. I have the /boot directory on my /dev/sda1 and it is using XFS. Is there directions on grub installations that I can follow aside from the gentoo install docs? |

xmltok,
Install grub manully with the command sequence | Code: | grub
root (hd0,0)
setp (hd0)
quit |
This puts the bootloader on the MBR of the first drive known to the BIOS when grubs files (your /boot) are in the first partition of that drive. If you have IDE HDDs then they are normally discovered before SATA or SCSI.
If your machine does not have a floppy, the first command needs to be Any error mesages you get from the above sequence will be useful.
Some BIOSes need the bootable partition to be flagged as bootable. Check with and use fdisk to change the flag if needed.

I had installed grub in that method before, without the --no-floppy option. I have since done this and enabled the bootable flag on my /dev/sda, which not set.
Unfortunately, this didn't make a difference.
I have checked by dd'ing the first 512 bytes of my drive to see if grub is in the MBR, and it is. My fdisk results are:
| Code: |
# fdisk -l
Disk /dev/sda: 799.9 GB, 799954436096 bytes
255 heads, 63 sectors/track, 97255 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/sda1 * 1 97006 779200663+ 83 Linux
/dev/sda2 97007 97255 2000092+ 82 Linux swap / Solaris

Do you have any other ideas? |

xmltok,
It sounds like the BIOS cannot see your hard drive, since if GRUB was loading at all, it would at least say GRUB:
You are presumably booting from a CD for your install and have no other drives than those attached to your RAID card.
Have you set the boot order in the BIOS to allow booting from the RAID card ?
Also, does grub see your RAID as (hd0). Try the following, where -> means press the tab key
Grub will list all the HDD is can see.
Be aware that the MBR is outside the normal filesystem. The RAID controller may or may not hide that from grub.
I suppose you are using as RAID ?
You wouldn't plug a card like that in and use it in JBOD mode.

Right, RAID-5.
The machine is booting off of the hard drive, there is no CD in the machine and no floppy disk.
Grub does see hd(0,0) my xfs partition that I have installed it to.
I had previously has FreeBSD installed on here and it was working fine, so the BIOS is capable of recognizing the HD, nothing has changed since I had FreeBSD installed.
Would I be better off just installing lilo? |

I have this same MB.
Have you set your BIOS to boot the offboard SCSI device?
By default the BIOS will only be set to boot the basic onboard stuff (FD, HDD, CD).

| Yeah, the machine boots up with GRUB fine, its when I reboot the server that I have a problem. The BIOS returns to its booting process as if it never found the OS on the HD. |
