How to boot from slave?

Hi, I have an old optiplex 270 that I am playing with. On thee master HD, I have 3 partitions, one for windows xp, one for ubuntu, and one for kubuntu. I just added a 40Gb drive as a slave and I would like to install the OpenSolaris OS on it. I am trying to figure out how to boot from the slave upon startup, but cannot seem to figure out the set-up menu. Could anyone please help me? I'm pretty new, so I don't even know if it is possible to boot from the slave--please help!

Thanks in advance,

 

Don

Hi Don,

Of course, it is possible to boot to an OS on any drive, provided boot.ini is configured correctly. You might want to ask for help in the operating systems forum for help, or a forum for OpenSolaris.

Re: How to boot from slave?

Thanks! I looked for tags for OS and OpenSolaris but found none. Isn't switching boot drives something I would configure in the "options" screen after pressing "F12" setup after the Dell splash screen? Since I would be actually booting from the disk, I just need the system to recognize the slave, or auxilliary drive as the 1st option, and I haven't been able to set that in the options screen. I feel fairly confident that I can navigate the installation once I know that is indeed going to the correct drive.

The boot.ini file points to available operating systems, so you need to know how to edit and configure the boot.ini file. I can't tell you more since I have very limited experience with this, but take a look at this page for more information.

Re: How to boot from slave?

Thanks, but I don't boot into windows xp (although it is on the drive). Upon power up, I go from the splash screen to the GRUB on Drive #! which lets me pick which OS I want (either Windows XP, Ubuntu or Kubuntu). My issue is that I can access the 2nd drive (which is where I have Solaris) on power up. I have tried changing some options in the F2 and F12 menus in the BIOS screen, for whatever reason, I'm not seeing where booting from drive #2 is an option. Any ideas? Thanks for your help!

I'm sorry, there were 2 errors in that post: it should read "Drive #1", and more importantly, "My issue is that I cannot access the 2nd drive..." Which was pretty much the issue! Please help!

Re: How to boot from slave?

Dell BIOS is a bit limited in what it will search for boot code.  Your computer has the ability to use either IDE/ATA drives or SATA drives.  If you have IDE/ATA drives you are using a wide ribbon cable having three connectors, one for the main board drive controller, one in the middle for the slave, and one for the master drive.  The BIOS will only look on the master drive for the initial boot code, which is why Osprey is pointing you toward the boot.ini file.  If you have SATA drives you have pretty much the same problem; the initial boot code must be on SATA 0, the first port on the controller.  To reach the OS on the slave drive your GRUB will need to be set up to load the necessary boot code from the slave drive.

There is one trick that you can use to boot from an IDE slave drive, and that is to go to system setup when you start the computer and set Drive 0 to off.  In that case the slave will be treated as the master and should allow you to boot from it.  I don't know if the same trick will work with SATA drives.

EDIT:  There is at least one exception to what I've written with regard to SATA drives; the BIOS can be set to boot from the RAID regardless of where they are attached.  My own system has the DVD/CD drive on port 0, nothing on port 1, and a RAID of two drives which are connected to ports 2 and 3.

Re: How to boot from slave?

You are very welcome, though I'm a bit uncomfortable with being compared to a deity.  There are quite a few here with more experience and knowledge than I.  I am very happy that in this case I knew something that would assist with your problem.

I wish you the best of luck.
