At first glance it looks like it. I disabled my NIC (via rhine) in
windows and compiled a module for it under colinux. It inserted fine,
detected the hardware and I even got an ip bound to it on eth1 (eth0 was
the colinux net dev). For some reason if I try to ping it says connect:
Because windows does recognize the device and it is simply disabled, it's
possible that it is being initialized somehow which confuses colinux. I
can say that after colinux picks up the nic windows can't enable it until
next reboot so something is going on at the hardware level. If I can find
a NIC that is not in windows's driver database so it sees it as
"(Yellow!)Ethernet Adapter" in unknown devices I'll try again and see if
linux can init the device. Incidentally, my nic is on irq 23 and does not
share an irq w/ other devices.
My guess is that since colinux is effectively slave to windows, it does
not have access to real hardware interrupts. Though, if this is the case,
it should never have been able to detect my hardware in the first place
unless there is a layer between windows and colinux which reports the
hardware in an indirect way. I have not actually played with other
devices like SCSI yet, but that's next.
