Hi *,
I have a DOS program which needs direct access to a specific PCI card
(Eyelink II eye tracker).
When I start the program (all ports are set in the dosemu configuration)
dosemu crashes with the following debug messages:
PCIBIOS: pcibios present
ERROR: Fault handler re-entered! signal=11 _trapno=0xE
ERROR: cpu exception in dosemu code outside of DPMI client!
trapno: 0x0e errorcode: 0x00000004 cr2: 0x00cf10ba
eip: 0x0808adc5 esp: 0xbfd44b10 eflags: 0x00010202
cs: 0x0073 ds: 0x007b es: 0x007b ss: 0x007b
Can anybody help me or is it not possible to use direct PCI access in
dosemu?
Here are more details:
The output of lspci for the card is:
04:02.0 Class ff45: PLX Technology, Inc. PCI <-> IOBus Bridge (prog-if 4c)
Subsystem: Unknown device 454c:1000
Flags: bus master, medium devsel, latency 64, IRQ 3
Memory at f7bfef00 (32-bit, non-prefetchable) [size=256]
I/O ports at dc00 [size=256]
Memory at f7bff000 (32-bit, non-prefetchable) [size=4K]
Memory at f7c00000 (32-bit, non-prefetchable) [size=1M]
Capabilities: [40] Power Management version 1
Capabilities: [48] #17 [0080]
Therefore I set the following parameters in dosemu.conf:
$_ports = "range 0xdc00,(0xdc00+256)"
$_irqpassing = "3"
$_pci = (on)
running dosemu 1.3.3 with
>> dosemu -s -DZh
and starting the program I get the attached boot.log
Thank you in advance!
best,
