What about running fdisk, and setting the Unixware partition to not active.
Can you then remotely change the CMOS so that the boot order is disk, network card, removable device.
On the next re-boot, the machine will boot from where ever the network card is connected to.

Thanks for that. Could you tell me how can i remotely change the CMOS. I have only a linux machine that is connected to this unixware machine and moreover i cannot get the Xwindow loaded. do we have command line tools on linux to do this??

Remotely changing the CMOS will depend upon whether the system board will permit it.
Are all the remote unixware systems reasonably identical?
I have assumed that you have a point of sale application with one unixware system per location connected to a central management system, with the store systems not having either diskette drive or CD drive.

Hi jgt,

thanks for your continuous inputs, i really appreciate your help. after a wild thought i ended up performing the task like this,

1. wipe out the mbr -> dd if=/dev/zero of=/dev/dsk/c0b0t0d0p0 bs=512 count=1
2. reboot the machine -> init 6
3. the system does not recognize the disk to boot from and it goes in the bios boot sequence and finally tries to boot from network
4. i have setup a pxe boot server which responds to this pxe request and install linux from there.

I could not use editing BIOS remotely as we have different kinds of boards and so i automated the above from pxe boot server into each and every machine.

thanks..
