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. :-)

Will PM if found
