Changes from X1 to X2

12All BAT54A (0-0031-1261) changed to BAT54 (0-0031-1104) due to wrong polarity

R712 changed from 10k to 15k to adjust voltage
3 PU R756 and R757 added @ U38.15 (PG_VDDR) and U38.16 (PG_V1V5)
4 Net on pins U3.54 and U3.55 separated (BSEL[0..1]) due to naming error

PU R758 added at CN34.7 (SYS_RESET#)5
6

PU R759 added at U39.4 (VIDPWRGD)
7

C717 changed from 4u7 to 1u
8

R607 not populated
9

R571 and R572 not populated (FWH Test Pins)

10

R585 and R586 not populated (for LVDS 18 Bit)

11

R760 and C741 added to U7.50 to generate a V_3V3SB input delay for resume reset

12

R501 and R494 not populated due to PCI config of LAN 82540

13

U36 FWH symbol changed due to wrong pinout (Pin 23, 24 and 25)

14

R496 changed to 4k7 and set to GND (PD M66EN)

15

R525 and R499 is now populated

16

R530 not populated due to wrong V_2V5LAN voltage

17

U20.G4 is now 51R Pulldown to GND

18

U20.H4 is now 33R Pullup to V_3V3LAN

19

AC97 Fixup (AC_SDIN0 -> Changed to AC_SDIN2 on ICH4)

20

Swap ICH4 Pin N20 and P21 (H_HISTB+ / H_HISTB-) due to wrong info in yellow cover

21

LAN 82540 Fixup (R519 populated with 0R, R517 changed to 2K49 and R513 changed to 330R)

22

R615 changed to 4K32 due to Cougar Bug

23

HW Rev changed to 2 at Glue Logic

24

R373 is now populated with 10M

25

CN12.4 must be isolated cause of shortcut of AUD_MIC_BIAS to GND

26

PU R761-R765 added to VID[0:4]

27

PU R766 added to U23.15, PD R767 added to U23.14 (Panellink strapping options)

28

HD-LED-power connected to V_5V0 instead of V_5V0SB

29

PD R768 added to PS_ON

30

PU R769 added to U3.28 (PGOOD408#)

31

PD R770, R771, R772 added to power enables (default off, if CPLD not configured)

32

PD R773-R776 added to serial port shut down pins

33

Splitted SMI# and PME# signals of SIO0 and SIO1 on ICH4-GPIOs

34 Removed R383, R384, R385
35 Added D25 to avoid crossvoltages from VGA Monitor
36 Added D26 to avoid crossvoltages LPT Port
37 Alternative population of L7 to L12 with resistors (0R)

PME# Signal of Cougar (PinB7) is set to V_3V3 via 0R38

39 U29 (LP3965EMP) can be replaced by an 0R_1206 to power 3V3 on Cougar
40 Possibility to PullDown Pin D8(MD24) on Cougar to enable SDRAM
41 CN41 (JUMPER 3x1) added to connect to MPCI Pins (TIP and RING)
42 V_5V0 input at V_DDR supply is now controlled by XILINX CPLD (Pin 25)
43 Delay of PWRGOOD# (LAN 82540EM Pin A9) to enable correct EEPROM detection
