Hi pludi,

This sounds complicated. If thts true, then its probably impossible to figure out what grub sees sdb as. But I feel the most obvious is that the first external disk is detected as sdb and grub sees it most likely as (hd1) afaik. The rest follows as sdc sdd.and so on.

"Background: I've had a SATA disc identified as /dev/sda or hd0 with Linux running, but couldn't boot from it as GRUB saw it after an IDE disk at hd1. So none of the entries matched anymore.

what was /dev/sda mapped to in device.map ? was it hd0 and still grub saw it as hd1?

Kind Regards,
Gaurav.

NAME
installgrub - install GRUB in a disk partition or a floppy SYNOPSIS
/sbin/installgrub [-fm] stage1 stage2 raw-device The installgrub command is an -only program. GRUB stands for GRand Unified Bootloader. installgrub installs GRUB stage 1 and stage 2 files on the boot area of a disk partition. If you specify the -m option, installgrub installs the stage 1 file on the master boot sector of the disk. The installgrub command accepts the following options: -f Suppresses interaction when overwriting the master boot sector. -m Installs GRUB stage1 on the master boot sector interactively. The installgrub command accepts the following operands: stage1 The name of the GRUB stage 1 file. stage2 The name of the GRUB stage 2 file. raw-device The name of the device onto which GRUB code is to be installed. It must be a character device that is readable and writable. For disk devices, specify the slice where the GRUB menu file is located. (For Solaris it is the root slice.) For a floppy disk, it is /dev/rdiskette. Example 1: Installing GRUB on a Hard Disk Slice The following command installs GRUB on a system where the root slice is c0d0s0: example# /sbin/installgrub /boot/grub/stage1 /boot/grub/stage2 /dev/rdsk/c0d0s0 Example 2: Installing GRUB on a Floppy The following command installs GRUB on a formatted floppy: example# mount -F pcfs /dev/diskette /mnt # mkdir -p /mnt/boot/grub # cp /boot/grub/* /mnt/boot/grub # umount /mnt # cd /boot/grub # /sbin/installgrub stage1 stage2 /dev/rdiskette /boot/grub Directory where GRUB files reside. See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWcsu | +-----------------------------+-----------------------------+ |Interface Stability |Evolving | +-----------------------------+-----------------------------+ boot(1M), fdisk(1M), fmthard(1M), kernel(1M), attributes(5) Installing GRUB on the master boot sector (-m option) overrides any boot manager currently installed on the machine. The system will always boot the GRUB in the Solaris partition regardless of which fdisk partition is active. 24 May 2005 installgrub(1M)
