Hi,

I try to enable direct hardware access). I tried different settings, but nothing works right.

I am using dosemu 1.2.2.0 and MS DOS 6.2

Extract of my dosemu.conf:

$_ports = "0x310 0x330"
$_irqpassing = "10 11"
$_hardware_ram = "0xD0000 0XD3FFF"

Thanks,

Steffen

I have successfully used direct hardware access in dosemu 1.2/1.3 and MS-DOS 6.2, using ports and irqpassing, but not hardware_ram. $_ports = "range 0x300,0x320 fast"
$_irqpassing = "5"
Apart from interrupt response sometimes being a bit slow it worked ok.
