Hi,
This is the output from the 2 commands:
bash-3.00#echo apic_support_msi/X |mdb -k
apic_support_msi:
apic_support_msi: 1
-bash-3.00# echo apic_msix_enable/X |mdb -k
apic_msix_enable:
apic_msix_enable: 1
bash-3.00#echo ::interrupts | mdb -k

I can also see that after typing ' echo ::interrupts | mdb -k " that e1000g
does seem to support MSI ,so what could be the problem here??
Also , as far as i can see, there are NO nvidia boards present on the system.
No, i am still downloading the latest version of Solaris ( 05/09) ,will keep
you posted on that
Any ideas on this one?
Thanks
Som
