Microdigital Omega Resources
pcimgr.txt Details of commands and summery of the PCI API.
Their is an additional SWI not listed in the document above 'Microdigital_CallDeviceVector' (&54003).
This probably sits on the unknown IrqV and uses it to trap calls from interrupts generated on the PCI bus.
I haven't tested though.
library.zip This is a library of example code demonstrating the PCI API.
pcidev.zip A small programme to list technical data about the PCI devices in a machine.
data.txt A Report from an Omega generated by the above programme. The machine under test had a TV card in slot 2, Ethernet card in slot 3 and sound card in slot 4.
All the interfaces except graphics hang off the PCI interface. Above is a fairly standard report generated by the 'PCIDevices' command. This machine has a sound, Ethernet and TV card in it.The TV card is listed as device 1 and 2 because the PCI interface sees the card as being 2 distinct devices, this may happen with other cards as well. Device 6 is the Omega's on board Hard Drive interface and devices 5 and 8 are the on board USB interface. As for devices 0 and 7 I can only really speculate.
