Dual Boot

Dual Boot

[William Bradley]

Is it possible to setup dual boot for Solaris and Linux with two
drives?  The Sun page gives instructions but only mentions partitioning
one drive.
Has anyone messed with this?

It works fine for me

Re: Dual Boot

[David Andrew - Sun MDE]

William,

The dual boot instructions are on that site because it is a little more 
complicated to set up a single disk for dual boot.  It is primarily directed to 
the Ultra5 which only has one disk. In fact, the disk druid provided in 
UltraPenguin shows you all the disks and existing partitions and gives you the 
flexibility to put bootable OS's wherever you want to.  The dual boot 
instructions discuss how to specify which partition you want to boot from; using 
separate disks has generally been the easiest way to provide multiple boot 
options.

As Matthew and David said, it's no problem. The Sun page will also
give you the description for one disk and booting from the monitor
mode using aliases. If you want to make a dual boot from a single
disk using SILO, you will have to read the following description.
It's a hack and it does NOT work using root directories on separate
disks. I sent it to Jakub and another guy who was interested in it
on the 24.Mar.'99, but haven't heard anything from them yet. So, here
we go:

it might interest you, that I managed to hack SILO 0.8.5 in such
a way, that I can use it for booting Solaris as well as UltraPenguin.
The work is based on up-1.1.9.iso CD-ROM from Feb 23 19:20 as found

Told in a few words: There is a problem with missing/additional "/"
at the beginning of a file-path and there is some code missing in
the ELF64 area. (I took out some leading blanks to fit the main.c
text in, but I still suppose that it will get mangled in the transit.
Apart from a few casts it corresponds to the code in ELF32 area.)

The configuration file looks as follows:

# cat /etc/silo.conf
timeoutP
partition=2
root=/dev/sda2
image=/boot/vmlinux-2.2.2.gz
        label=linux
        initrd=/boot/initrd-2.2.2.img
        read-only
image=1//platform/sun4u/kernel/unix
        label=solaris
        solaris
#

Note again the double-slash in Solaris "image" line - NOT necessary
if you type at prompt!

The disk is organised so, that the first partition (128MB) is Solaris
"/", second partition (128MB) is UltraPenguin "/".

UltraPenguin installation was done after Solaris with
"bootloader: MasterBootRecord (/dev/sda)".

Under Solaris the file /platform/sun4u/ufsboot was copied to "/".

The machine is Sun Ultra 60 Creator 3D, 128MB, 2*9GB, 360 MHz.
Solaris is Solaris 7.

Hmm. I suppose that's all.

Perhaps once more: It's a hack. I don't really understand the "problem
of missing slash" and the compiler is warning me about the casts. But
it's working.  :-)

It's hard to hook up a serial console on K220?!

Under HPUX, "setboot" command can set the primary boot path
so it can reboot from any disk/lan you want. You would have to
write a similar program for parisc-linux to poke stuff into NVRAM.
It might be a PDC call to do it; I don't know. But it's doable.

dual boot

[Anna G. Zapata]

Hello all,

I would like to install RH 8.0 on my W2K laptop (a dual boot).  I entered
the installation program without a problem and finally came upon the
partioning section of the setup.  I clicked to use an automatic partition
and clicked next.  I was told that there wasn't enough disk space, but I
know that I have a little over 2G on the drive.  Does anyone have any
suggestions as to what I'm doing wrong?

Thanks.

I don't know RH 8's setup routine, but I would guess that it would either:
1) expect to find an already-formatted (ext2, ext3, reiserfs) Linux
partition on your system (and maybe an already-created swap partition as
well); or 2) would expect to find some free space on the drive (space not
yet allocated for another OS).  A third possibility, and one I see Knoppix
includes in their latest release, is that the install routine would offer
to resize an existing partition to make space for the installation.  Not
knowing RH 8, I can't say with which of these you may have been confronted
- if any.  But your description seems to indicate that maybe you've
alloted the whole of your laptop's drive space to W2K.  If you have, and
if RH 8 comes with no disk resizing capability, then it would most likely
indicate that there was no space on the disk for the install.  If that's
the case, until you free up some space for a Linux partition, you won't be
able to install Linux.

Caveat to that last statement: you can run Linux from a DOS/Win filesystem
(as long as it's not NTFS, IIRC) using certain distros - I think WinLinux
is the name of one such distro.  I doubt RH can do this though.  There are
certain performance hits in using this approach, as I understand it.  So,
you need not necessarily resize/repartition your disk to run certain types
of Linux.

Re: dual boot

Nothing
 
You don't have large enough HD for a dual boot and data.

On my laptop I have a 50 GB partitioned as follows.
hda1 10 GB Windows XP
hda2  20 GB Common Data
hda3 100 Mb  Linux /boot
hda4  10 GB   Linux /
hda5   10 GB  Linux /home

Point is I am not sure I have enough HD if I attempt to edit or record 
realtime data.

Others have offered some guesses about what your problem might be. No one 
can do mroe than guess, however, because " I have a little over 2G on the 
drive" is not very clear. Are you referring to the size of the drive, the 
unused space in a Windows partition, or the unused space not currently in 
any partition? If the first, your situation is probably hopeless. If the 
second, you will need to do some work, or switch to a different distro (as 
someone else suggested). If the third, then I'm surprised that you are 
having problems.

Offhand, I do not know how much space RH 8.0 requires to install, but I 
would expect 2 GB to be enough for a basic install (I can install a minimal 
Debian in about 200 MB, for example). If RH needs more space than that, 
shame on Red Hat ... it is using an awfully demanding and inflexible 
installer. But you do need the 2 GB in the form of unpartitioned space, so 
the RH installer can create an ext2 partition (and probably a swap 
partition too, unless your laptop has unusually generous RAM) for Linux to use.

RH used to ship with a partition resizer, an app that allowed you to make 
an existing (Windows, usually) partition smaller to make room for a Linux 
(ext2) partition. You might see if whatever version of RH you have offers 
this capability (I think it was called Partition Magic or something similar 
to that).

Even if you get RH to install on this system, you are likely to be limited 
in what it will be able to do. I'm not sure what Frank means by "realtime 
data", but certainly some data (e.g., mpeg or DivX video) is sufficiently 
demanding of disk space that a 2 GB partition would be woefully inadequate 
(for perspective, the system that I store edited video on has about 450 GB 
of storage). Still, 2 GB should be enough to give you a system that is 
usable for many purposes.
