So, how do I configure GRUB to find the USB/eSata drive? (I am using a dual USB/eSata port on my laptop, and the USB/eSata drive is using the eSata interface. The BIOS is configure so that the boot sequence is first from a CD/DVD drive, then from a USB drive, then from

So from what you've described your external drive is seen by
as an internal drive.
So what is the internal drive boot order set to in the BIOS?

Thanks Dave for replying! The BIOS does not differentiate between the boot order of internal v.s. external disk drives. There is just one
for setting the boot order, and the 3rd priority boot device is set to 'USB Hard Drive' This leads me to believe that the BIOS does understand about external USB hard drives that are plugged in to some USB port on the laptop. (and I assume also eSata drives plugged in to a USB/eSata port)
However, your question got me to take a second hard look at the BIOS menu and I noted that in the main menu there is a section titled 'Device Information' and under it I only see the Internal HDD and the CD/DVD devices listed... To my untrained eyes, that seems inconsistent as I had the USB/eSata hard drive plugged in when I rebooted the laptop and brought up the BIOS menu...
So I dunno if the BIOS is broken, or just does not show any
drives in the main menu.... But the fact that there is an option in
boot order to boot from a USB Hard Drive implies it is ok to do so... So I remain bewildered...

Just a quick thought. Quite a while i tried to do the same, install a test-version on an external disk. Al went well, allthough one should use the extended
(not auto-config), as the new boot loader + grub stuf are by default installed on the first disk, while one should rather have it also on

The GRUB auto install indeed tends to screw up in the openSUSE installer. It just want to sit on the first hard disk. I'm running also from an USB disk for some time now. How to set up in openSUSE installer: When you get to the installation overview, click bootloader Select Advanced > Edit configuration files manually device.map: Change the disk order, so that your external drive becomes (hd0). Grub always sees the disk from which it is booted as hd0, but the installer tries to name the external drive as hd1 (or anything higher than your internal disks) menu.lst Change all boot entries pointing to your external disk to hd(0,X), where the X is to be replaced by the partition where /boot resides on. In this case /dev/sdb1 is (hd0,0); /dev/sdb2 is (hd0,1) etc. Save and exit the configuration files. Now comes the tricky part, somewhere you have a screen where you can change the order of disks (somebody help me out here, it has been a long time). Anyway, just have a look at the screen, but don't change anything. Just save and exit. When you opened the screen, the manually edited configuration files where read. Upon save and close, these changes are updated to the installer. Without doing this, strange things will happen. Now enjoy the install and your booting openSUSE system!
