IIRC, The CV64/3D should map into your FAST mem area on a stock A4000.  So, if you have 16MB Fast, 2MB Chip, and a 4MB CV64/3D, when you boot, you should have....
~2MB Chip
~12MB Fast
4MB missing (not listed in avail, but reserved for the CV64/3D)

If this isn't the case for your system, you might want to see if a jumper is mis-set on your CV64/3D.

The A4000 will map ZorroIII cards somewhere in the address-space 0x10000000 to 0x80000000 which is reserved for ZorroIII-cards whilst the motherboard memory is configured somewhere in the address-space 0x01000000 to 0x08000000 which is reserved for motherboard resources so they wont use space from eachother :).


Hmm... Correct you are.  According to sysinfo on my A4000, I have my CHIP and motherboard FAST under 0x08000000.  Then I have my CyberStorm mk2 at 0x08000020-0x0C000000.  While my CV3d is way out at 0x40000000.  

Yet, when I boot, I come up short 5MB of ram.  (1 for my kick, and 4MB for the CV3D.)  

Of course, when I boot with no startup, I have all my RAM.  Ooops.... Disregard my comment about jumpers.  Hmm, the memory allocation must be something the CyberGraphX software does.  Whoever said SOFTWARE ERROR may be on to something, after all.  ;-)  Chalk up that mistake to my bad memory.  haha!  Sorry 'bout that.
