Actual config is:

Sonnet crescendo G3 400

GFX TwinTurbo128

Atto scsi uw with 73 gb hdd

Cd-Rom at scsi onboard

Ram: 6 modules 64mb 6ns gold, 2 modules 16mb gold. In pair... A1,B1 etc...

I already tried with different memory layout (128mb to up), without gfx, without cd-rom, with original cpu and without ATTO... with no difference. But when I have time I wanna retry
