The relevant code is:
/**************************************************************************
Allow disabling of Non-Maskable Interrupts in I/O space, to
support validation.
*************************************************************************/
if( adapter->RegistryNMIDisable )
{
UCHAR RegisterVal;
RegisterVal = inb( ET1310_NMI_DISABLE );
RegisterVal &= 0xf3;
if( adapter->RegistryNMIDisable == 2 )
{
RegisterVal |= 0xc;
}
outb( ET1310_NMI_DISABLE, RegisterVal );
}
This conditionally writes to a (PC) interrupt controller register. As
the comment says this can be useful for validation, but is totally
unsuitable for production use. All the NMI disable code can be removed
from this package.
