 |
|
Well, first is this possible? Second, the scsi drive has Solaris 10 on it.
I have a laptop which dual boots between Gentoo/Windows. I bought a 120g Western Digital scsi drive(usb2.0) for back up and other purposes. I decided to install Soaris 10 on it. So far the scsi drive has a 40g solaris partition and a 40g fAT32 partition. The Solaris partition is primary, and is listed by fdisk as /dev/sda2. The install went smoothly, I just can't boot to it. I have tried the following entry in grub.conf:
| Code: | title=Solaris 10
root (sd0,1)
makeactive
chainloader +2 |
I have also edited the
line in almost everyway possible but still can't get it to boot.
It says "error 23: trouble parsing number"
When I listed the scsi drive as (hd1) its says "unkown device".
Anyone have any suggestions?
THanx
PS - I apologize for putting a Solaris issue here, but I think its mostly about grub

Ok - after further investigation, it appears that grub sees all hardrives as (hd?). When I tried listing Solaris as (hd1,) - I got the error:"device not recognized" Anyone know how grub sees a SCSI hard drive as bootable?

It's not really SCSI is it? You mention USB. I've never seen a SCSI USB drive. Being that it connects by USB I'm guessing it is using the SCSI generic module just like a flash drive would, which would explain the kernel seeing it as /dev/sd...
I'm not certain how you'd attack such a situation. When you're in grub (in the setup phase) the TAB key can help with device name completion and things like that. Grub should be able to help with that. Check the man pages for grub. |

You are on the money there Drunkula. Its not actually scsi. The porblem with doing what I was trying to do is that the BIOS doesn't see the the drive or assign it a device ID during start up. I'm not sure if its possible on a laptop buy I'll goggle it a few time to check. Will post if I find anything relevant.
