Well, I checked IRQs under Windows and it appeared that my video card and
network card share the same IRQ (16). Sound card is integrated into the
motherboard, so I cannot change its IRQ, but it has nothing to do with the
conflict anyway as it uses IRQ 23. Under Solaris the hardware components get
different IRQs. However, the video card and network card still share the same
IRQ (11). My video card is plugged into the PCI Express 16 bit slot and the
network card is integrated into the motherboard. I suspect that the network
card is internally connected to a PCI Express bus as its model is Realtek
RTL8168/8111 PCI-E Gigabit Ethernet NIC - I guess "PCI-E'" means the PCI
Express bus. My BIOS allows me to only set IRQs for PCI slots, so I'm unable to
explicitly change the IRQ for my video card. I tried disabling COM port, LPT
port and my Floopy drive to release some IRQs, but my video card and network
card still share the same IRQ, now it is IRQ 10. Maybe, my motherboard is
designe
d so that all PCI Express buses share the same IRQ, I don't know. However, I
do not see a way to separate IRQs for the conflicting devices under Solaris, so
I'm frustrated a bit. It seems that I won't be able to work under this OS in
the near future :-(
