First, I'd like to thank all guys who reported about successful NV30/35->QuadroFX modification with Detonator 44.03 using SoftQuadro4 scripts. It was a surprise for me and due to their reports I investigated this issue deeper and I can confirm that _some_ boards (probably GFFX only) are really moddable with SQ4 using early DetonatorFX versions (starting from 44.03 up to the latest non-encrypted 44.65). The explanation is pretty simple: NV's SQ4 protection system seems to be screwed for some boards in these drivers. Currently I've tried to use SQ4/NVStrap/NVStrap antiprotection for NV18 (the protection seems to work fine, OGL applications cause PC lockup during OGL context destruction) and NV30 (the protection doesn't work). I've also tried to update SQ4 for newer drivers and modded NV30 seems to work fine on 45.xx drivers too. In 5x.xx drivers modded NV30 behaves the same as GF4 - the OGL applications cause PC lockup. So the protection seems to be fixed. I'm not pretty sure if the hole in protection system is NV3x specific or it applies to some NV17/18/25/28. So any feedback is welcome.
