NEO 2.2 install Problems - 2 screws leftover

[stevem]

After fitting a neo key to my kids' PS2 just before chrimbo I thought I'd go the whole hog and fit an internal neo 2.2 in their cousins machine (3003 v4)
However, after fitting 4 chips and none working can anyone advise the following:
1. Has anyone successfully programmed a c12508a chip using elvis programmer.-Please mail me if you have.
2. I have 2 bronze coloured (largish) screws leftover. They're not the ones from the fan housing. Can anyone tell me where to put these(in a polite way).
3.Should I cut 3 wires to see if the 5 wire setup will work.

After the original fitting failing on the dvd draw not opening I removed excess solder between points 5 + 6 it then opened and the X button caused the drawer to open too.
ps I've seen posts saying elvis cant program this hex but the manufacturers claim it is possible providing you obtain the calibration figures for the blank then put this figure into the hex .I've seen 1 post(somewhere) of someone claiming to have done but dont have the details now.


Thanks in advance
