I was trying to use the X-24 in my old rig
P3 1GHz (core coppermine, 133mhz)
2x256MB Pc133
all mounted on a HP Vectra VL400 DT (desktop)
I've installed the official Q3D Obsidian2 Drivers 6CF but the system hangs
Sometimes I can't see the screen properties (with a strange error message) and sometimes I can see the properties without the Q3D panel
Any idea?

p.s.
I have two X-24 and both have the same problem
Under Windows Xp both run well

hi, I think disabling CPU to PCI post write will solve the problem, but this will decrease performance.

No problem Quantum3D Obsidian drivers seem to be quite problematic on anything higher than a 440bx motherboard. Something like that happened to me when I fired up my 200SBi on an Athlon 2800. You can opt to do what I said or just use the normal V2 drivers by throwing the following variables into regedit's 3dfx interactive glide and d3d section:

SSTV2_FT_CLKDEL = 5
SSTV2_TF0_CLKDEL = 7
SSTV2_TF1_CLKDEL = 7
SSTV2_TF2_CLKDEL = 7
SSTV2_SLIM_VIN_CLKDEL = 3
SSTV2_SLIM_VOUT_CLKDEL = 2
SSTV2_SLIS_VIN_CLKDEL = 3
SSTV2_SLIS_VOUT_CLKDEL = 2
SSTV2_GRXCLK = 90
