ZEN 6.5.2 on NetWare 6.5 sp4

Confirmed machines affected:

HP Compaq nc8230 Laptop
HP dc530 desktop

Using scripted imaging and deleting partitions with the img pd commands then
recreating partitions with the img pc commands and laying down base and add
on images.

Images appear to lay down correctly however on reboot I get a blinking
cursor in the upper left corner of the screen and nothing else.

If I boot to Maintenance mode and delete the partitions with fdisk and
reapply the image (either manually or automatically) all works well.

Had the same problem with SATA however a BIOS change fixed that. I set the
SATA emulation to Combined and imaging works just fine on those machines.

I believe there is a simple solution I am overlooking.

Does anyone have an Idea on how to fix this?

Thanks in advance.
