Hello all,

I have read about dual boot of SCO and Win95, and am aware that it is
a simple task by just type 'dos' at the boot: prompt.

But now since I have a > 4G harddisk and have installed Win95 and SCO
both occupying about 1G of space, how possibly can I put in another
Linux in the same harddisk and boot among all OSes???

In fact I have tried to installed System Commander 4.0 with the hope
that I can do multiple boot with SC4. (I installed SC4.0 after SCO)
But the SC4 'hang' half-way after showing the copyright message though
I set the active partition to the Win95 partition and had SC4 do the
necessary modification to my boot sector. (Of course I recovered by
restoring the partition information by Norton rescue.)

If I put in Linux at the 3rd primary partition and have lilo installed
only at the partition, have anyone tried that and actually got it to
work?

You may think I am crazy, but I intend to later install Solaris x86 on
another harddisk (slave one) and hope that I can 'tame' the 4 OSes
under my control .... anyone out there to give me some tips.

Thanks.

This sounds familiar...

1) Set SCO to the active partition
2) Boot to SCO
3) use fdisk to find out the partition numbers the other OSs are on, and
write them down
4) vi /etc/default/boot
5) add the line 'linux bootos <l>' where <l> is the partition number linux
is on
6) add the line 'win bootos <w>' where <w> is the partition number windows
95 is on

This sets up bootos aliases of linux and win to choose at startup.
Pressing return or timing out will boot to SCO.
I have tried this with Win95, but not with Linux. However, as long as you
use the right partition for the Linux lilo
in the alias, I don't see why it wouldn't work.

I am booting OSR-5.0.2, NT, Win95 and Linux all off one 6.2Gb
disk without any boot manager.  Win-95 is in a FAT file system and
NT in an NTFS (so they both run happily).  I loaded Linux in the first
logical sector of the extended partition.  After configuring LILO, I
copied the portion of the boot sector which precedes the partition table
space from the Linux logical partition to the boot sector of the
extended partition.  The logical partition does not
start until after the first track of the extended partition.  SCO is
my active partition and I have the following entries in /etc/default/boot:

        nt=bootos nt
        win95=bootos dos_32
        linux=bootos dos_ext

Thus by default I boot into sco, but by typing "nt", "win95", or "linux"
at the boot prompt, I get one of the other OSes.  Linux works because
the SCO boot program executes the bootstrap routine in the boot sector
of the extended partition.  That is the LILO program configured to boot
Linux out of the first logical partition.
