Switch Settings
The 80321 board is highly configurable through a number of switches and jumpers. RedBoot makes some assump-
tions about board configuration and attention must be paid to these assumptions for reliable RedBoot operation:
•
The onboard ethernet and the secondary slot may be placed in a private space so that they are not seen by a PC
BIOS. If the board is to be used in a PC with BIOS, then the ethernet should be placed in this private space so
that RedBoot and the BIOS do not conflict.
•
RedBoot assumes that the board is plugged into a PC with BIOS. This requires RedBoot to detect when the
BIOS has configured the PCI-X secondary bus. If the board is placed in a backplane, RedBoot will never see
the BIOS configure the secondary bus. To prevent this wait, set switch S7E1-3 to ON when using the board in a
backplane.
•
For the remaining switch settings, the following is a known good configuration:
S1D1
All OFF
S7E1
7 is ON, all others OFF
S8E1
2,3,5,6 are ON, all others OFF
S8E2
2,3 are ON, all others OFF
S9E1
3 is ON, all others OFF
S4D1
1,3 are ON, all others OFF
J9E1
2,3 jumpered
J9F1
2,3 jumpered
J3F1
Nothing jumpered
J3G1
2,3 jumpered
J1G2
