B.25 PCI Bus Map
Table B-25: PCI bus map
Function Signals:
Device ID INT# pin GNT# pin
Onboard LAN AD21 INT D GNT A
Onboard SCSI AD20 INT A GNT B
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-6359VE/F, SCSI devices use "GNT B"
signals via PCI slot 2 and LAN uses "GNT A" via PCI
slot 1. Therefore, both PCI slots cannot be used for
plug-in bus master add-on cards such as a SCSI
card or LAN card.
