Hi Folks
Is there any support for the MHZ2250BH or any way to force the PCB into Kernel mode for ROM reading?
No external ROM on these boards

*Sorry I did post on the Ace forums but this board has a lot more traffic*
Thanks
Leigh

I presume you have a duff PCB?
I have had a few like this and had to search high & low for a compatible PCB and in most cases found one.
Post the pic of the drive label and I'll see if I have one.

While I remember that job being sorted we'll have to dig through the case notes.
Will PM if found
