Re: [hatari-devel] HDDriver issues with WinUAE CPU core (and with EmuTOS)

[Uwe Seimet <Uwe.Seimet@xxxxxxxxx>]

Hi Eero,

Just start HDDRUTIL, then go to "Devices and Partitions", select the
HDDRIVER file you want to configure and switch on/off the devices you
are interested in.

Since SCSI/DMA is not supported by Hatari it might probably be better if
there was a bus error when accessing these addresses. At least Hatari
should behave like it behaves when you access these addresses in
ST-compatible mode.

Take care

Uwe
