Does anyone know if there's an updated set of driver roms for the 2090a,
that allows you to run with data cache on on an 030 ( i.e. the code for
the driver should flush the d-cache on DMA completion ).
 
I had a browse thru the one's on my 2090 the other night ( hddisk.device
34.4 ) and they don't do this - I have a feeling someone had posted news
to that effect before. What's the current version of hddisk.device ( or 
should I say most recent - I gather the 2090a is out of production now
the 2091 is out ).
 
Whilst turning on d-cache isn't going to give me huge speedups, every
little bit helps. And I'd much rather use CBM official drivers than
try and patch the code myself ...
