Function Signals:
Device ID INT# pin GNT# pin
Onboard LAN1 AD24 INT C GNT E
Onboard LAN2 AD25 INT D GNT A
Onboard SCSI AD19 INT B, D GNT F
PCI slot 1 AD31 INT B, C, D, A GNT A
PCI slot 2 AD30 INT C, D, A, B GNT B
PCI slot 3 AD29 INT D, A, B, C GNT C
PCI slot 4 AD28 INT A, B, C, D GNT D
Note: In the PCA-6005E2 and PCA-6005F, the LAN2
controller uses "GNT A" signals which is also
used by PCI slot 1. Therefore, PCI slot 1 cannot
be used for plug-in bus master add-on cards
such as SCSI cards or LAN cards.
