Hi all
Also posted to comp.sys.hp.hardware, but knowing the breadth of knowledge here.........
We have 6 Z400/420 series workstations which seem to be prone to a boot fault.
The first machine to suffer has had the motherboard replaced twice. The second more recent machine has just last week had the mobo replaced.
The problem is that the first machine has started exhibiting failure signs again.
Basically the machine boots as far as the HP splash screen. It shows a blank inset window labelled "Mini ORom Display" and either hangs there or shows a blinking cursor.
When booting successfully, the Mini ORom Display window populates with text as part of the process.
It appears that the Worstation is even getting as far as reading the system ROM.
So the question is: what causes this sort of early boot failure? The fact that one machine has had motherboard replacements and has still hung once suggests it's not entirely mobo dependent.
The machines are approx 2 years old and still covered under HP 3 year 4 hour warranty, but I want to find the cause if possible before the warranties expire.
Thanks
Phil
