4
Enable incoming mailbox interrupt. This bit allows a write from the PCI bus to the incoming
mailbox register identified by bits 3 through 0 to produce an Add-On interface interrupt. This bit is
read/write.
3:2
Incoming Mailbox Interrupt Select. This field selects which of the four incoming mailboxes is to be
the source for causing an incoming mailbox interrupt. [00]b selects mailbox 1, [01]b selects
mailbox 2, [10]b selects mailbox 3 and [11]b selects mailbox 4. This field is read/write.
1:0
