MHZ2250BH Kernel mode?

[DataWreck]

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

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.

Yep your correct the PCB is not playing ball.

Cheers mate

Any success? Have an identical disc, same rev.nr. It spins and i can hear the head moving. Need another pcb or any other ideas?

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

Will PM if found
