1Design Clocks not working. W185 enables are tied low; should be tied
high.
EN1 and EN2 should be connected to
+3.3V. Only EN1 is required.
1. Cut trace between U1 pin 18 and ground
via.
2. Connect U1 pin 18 to U1 pin 16 (+3.3V).
For X4: Connect pin 18 of U1 to +3.3V.
X3 A
2Design Soft-power inoperative. VBAT needs to be ~3.0V.
Coin cells are 3V, cabled batteries are 4.5V.
R44 values must be selected based upon
battery used.
If CR2032 Coin Battery used:
1. Remove 0 ohm resistor on half of dual-
resistor component R44 nearest ATX
power header.
If Rayovac Cabled Battery used:
1. Install 100K ohm resistor on portion of
R44 nearest National SuperIO.
2. Install 27K ohm resistor on portion of
R44 nearest ATX header.
For X4: Use two discrete resistors; stan-
dardize on coin cell.
X3A
3Design Soft power not working. No pullup allowed on PS_ON.1. Cut trace between RN72 pin 5 and via
connecting to VCC3.3.
For X4: Delete pullup.
X3 A
4Design PCI arbiter not working. No pullups on SLOT_REQ(1:4) Connect (4) 4.7K ohm resistors between
SLOT1/SLOT2/SLOT3/SLOT4 pins
B18 and B19 on the bottom of the board.
For X4: SLOT_INT(1:4) on page 19 should
be for SLOT_REQ(1:4).
X3A
5Design None. SLOT_INT(1:4) pulled up twice. None.
For X4: Remove redundant pullups.

6Design None. WB_GNT(0:4) pulled up twice. None.
For X4: Remove redundant pullups.
X3A
7Design Slot 3 interrupt not respond-
ing. Slot 3 INTA/INTB pins connected incor-
rectly. 1. Remove all solder on SLOT3 pin A6.
2. Cover pin with Teflon or equiv. insulat-
ing sleeve.
3. Connect SLOT3 pin A6 to SLOT3 pin
B7.
For X4: Connect INTA# to SLOT_INT(3),
INTB# to SLOT_INT(4).

Errata 7: SLOT3 Interrupt Connection
OVERVIEW
The SLOT #3 INTA# and INTB# interrupts are wired incorrectly.
WORKAROUND
The work-around corrects INTA# only. A multi-interrupt card should not be used in SLOT
3.
1. Remove all solder on SLOT3 pin A6. Place Teflon sleeve over pin.
2. Connect SLOT3 pin A6 to SLOT3 pin B7
