I have an X3CE and a v1.6 (1.6a not b ). I rebuilt the LPC with wires, then redid it with the quicksolder board, then switched to wires again while double-checking the solder job. I resoldered all my points 3 times and in the process I broke a trace (pin8/lad2) but fixed it n/p. Despite all my tests and checks and redos, the chip when connected will only FRAG.
When the chip is installed and power is applied:
- Both the 3.3V and 5V LEDs are lit.
- The un/protect red/green LED is lit which matches the flash protect switch setting.
- The X on the bank select panel, the logo is red.
After power is applied, it will do 1 of 4 things, depending on how it is powered up:
- Power pressed quickly - 3 x boot then FRAG
- Power held - 3 x boot then FRAG, no delay from holding power
- Eject pressed - 3 x boot then FRAG
- Eject & Power pressed - Does nothing
I have used both "on on off off" and "off on off off" with no difference.
I have used every bank setting in the documentation with no difference.
When I remove the D0/LAN/HDD cable from the chip, it boots to the stock BIOS and runs perfectly.
I have tested using a multimeter from the pins on the fron to various test points which are shown in these pix. 'FRONT' is not my board, but is the clearest pic I could find of the front of a 1.6 board. 'BACK' is a scan of my LPC rebuild. All points are shiny, they look darker in the scan than they really are.
I attached D0 to the front the last time I redid all my points to rule that out as bad.

- Point ( A ) and the grey wire on the D0/LAN/HDD harness are connected. ( A ) is also connected to the unmarked point to the right of the "8" under point ( C ). The grey wire from H0/LAN/HDD is soldered to this unmarked point rather than the recommended D0 point on the bottom.
- Point ( B ) and pin 11 (LAD0) are connected.
- Point ( C ) and pin 8 (LAD2) are connected.
- Point ( D ) and pin 10 (LAD1) are connected.
- Point ( E ) and pin 7 (LAD3) are connected.

- pin 01 connects to ( a )
- pin 02 connects to ground
- pin 05 connects to ( c )
- pin 07 connects to ( d ) and ( e ) and also ( E ) from FRONT (LAD3)
- pin 08 connects to ( f ), ( g ), ( j ) and also ( C ) from FRONT (LAD2)
- pin 09 connects to pin 15
- pin 10 connects to ( h ) and also ( D ) from FRONT (LAD1)
- pin 11 connects to ( i ) and also ( B ) from FRONT (LAD0)
- The lost trace is at ( f ) and is repaired by routing ( f ) to pin 08 to ( j )
- ( b ) connects to ( A ) and the unmarked D0 from FRONT. I moved D0 to the front while debugging.
I believe I did these when the chip was OFF. The voltages I get with my ANALOG meter are:
- pin 01 - 1.8 (does not match FallsInc's LPC Voltage Diagram)
- pin 02 - ground
- pin 03 - 0
- pin 04 - x
- pin 05 - 3.3 (match)
- pin 06 - x
- pin 07 - 2.3 (does not match FallsInc's LPC Voltage Diagram)
- pin 08 - 2.3 (does not match FallsInc's LPC Voltage Diagram)
- pin 09 - 3.3 (match)
- pin 10 - 2.3 (does not match FallsInc's LPC Voltage Diagram)
- pin 11 - 2.3 (does not match FallsInc's LPC Voltage Diagram)
- pin 12 - ground
- pin 13 - 3.1 (does not match FallsInc's LPC Voltage Diagram but close)
- pin 14 - 3.1 (does not match FallsInc's LPC Voltage Diagram but close)
- pin 15 - 3.3 (match)
- pin 16 - x
I checked all the pins and only 09 and 15 are bridged. 13 & 14 are not, and neither is 07, 08, 10, or 11.
Well, it's late and that's about all I can think of. If you have any questions, let me know. I think I covered everything. Oh, my theory is that the soldering is good, but the chip is completely blank, including the backup. Hopefully someone will see something on the scan that I missed...
