double OS

Hi,
How can I install both Windows98 and QNX on one hard disk, and should I
install Windows98 or QNX firstly?

Hi,
you should install Win98 followed by QNX. Win98 bootloader can load
only Windows while QNX bootloader can load other OSes.

Even if you have already installed QNX, you can still install Win98,
but you will have to use a boot up disk to set the active partition to your
QNX partition, then run the fdisk utility from your QNX partition and use
the QNX bootloader rather than your Win98 bootloader.

If you are installing the RTP, you can simply run your installation
program in Win98.

Go with Win98 first. It will overwrite the master boot record no matter when
you install it, so if you try QNX first and then Win98, you will lose access
to QNX unless you’re using a boot disk.

I would actually go the other way on this, though it does not matter
much. If you install QNX first, then you can partition the disk the
way you like it. Windows tends not to give you great choices in how
your disk is laid out.

When you install QNX, you get the QNX boot loader. Subsequently you
install Windows, which wipes out the boot loader and replaces it with
the Windows loader that doesn’t recognize the existence of other
operating systems. When you boot Windows, use fdisk to change the
active partition back to the QNX partition, reboot, and you are back
in QNX. Now run fdisk under QNX, and replace the boot loader with the
QNX loader again. You can set either the Windows or the QNX partition
as the default.

In the end, it doesn’t really matter which you install first, so long
as you are happy with the disk layout choices you have by whichever OS
you install first.

Which way do you like ? The whoole disk ? Half of the free space ? 1/3 ?
1/4 ?
Would you call that a reasonable fdisk utility ?

However I use the QNX bootloader to boot QNX, after rewriting the MBR
from a DOS batchfile.
The reason is : I use more than 4 primary partitions and have to rewrite
the partition table to ‘unhide’ the QNX one, which is located at the end
of my HD, beyond cylinder 1024.
I still would like to know two things :

  1. how to set up the time up in the QNX bootloader (it’s to short
    actually)
  2. Is there something like a ‘rc.shutdown’ in QNX, where I could ‘dd’ my
    partition table back ?

Partiton Magic may help to create a partition wherever you want and
remove it, in order to show the QNX Setup unpartitionated space.
